Provide door hardware as per the CPS Door Hardware Schedule and Specifications.

• Administrative Suite
• Security Guard Station(s)
• Kitchen Office

• Main Entrance Door
• ADA Accessible Entrance Door
• The main building entrance closest to Staff Parking Lot
• The main building entrance closest to Playground/Playfield and Athletic Sports Fields
• The main building entrance closest to Annex/Modular Buildings
• The entrance to each Annex/Modular Buildings
• Food Delivery entrance adjacent to the Kitchen

Provide electric strike door hardware and KeyPad/KeyCard for immediate door access function.

Provide electric strike door hardware and KeyPad/KeyCard for door remote control access function from a specified remote Master Station located off site to work in conjunction with the Genetec Security Camera System.

Provide the following devices on exterior doors per CPS Office of Safety and Security criteria:

• Door contacts on all exterior doors.
• CCTV locations near all exterior doors.
• Provide override function key switches for all accessible doors in order to allow the building engineer to lock down the building after hours.
• Exterior Door with Vision Panel Window Guard Locations: For all projects, final locations shall be coordinated with CPS School Safety and Security.

All Door Hold-opens shall be tied to the Fire Alarm System. Doors provided with hold-opens shall be determined during the AOR’s design phase. Hold opens are typical at the following locations:

• Stairwell doors
• Link doors (located between buildings or parts of buildings)
• Dining Room doors
• Multi-purpose doors
• Gymnasium doors
• Servery doors
• Main Entrance doors

• Closers with opening force not exceeding 8 lbs shall be provided. Closers with dead stops should not be used. Closers shall be spring-arm closers if a closer stop is required. Otherwise, specify one with no stop at all and wall stops or floor stops. Regular arm and parallel arm closers should have heavy duty arms equal to LCN “EDA” or Norton “HD”.
  • Door Closer Hold Opens: Exterior doors where deliveries are made should include the hold-open function on the closer. Often this includes the front entrance doors, kitchen doors, yard storage, and cafeteria exit doors where the garbage is taken out. This sometimes may also include some entrance doors where the school holds the door open for the students entering in the morning. The reduction in wear on the doors, frames, and hardware at these openings would be significant. The doors requiring closers with hold-opens to be determined during the design phase.
  • Kitchen Doors and Delivery Doors: Levers shall never be used on exterior doors. These doors should have the spring arm closers with hold-open function (90% of the failure of the kitchen doors are due to manually propping or wedging them open for deliveries), square-bolt or guarded-bolt panic devices with cylinder dogging, continuous hinges, and exterior fixed pull and cylinder. Also, the swing of the door should be coordinated with the path of delivery travel to prevent awkward access during delivery of items.
• Strike Plates: Strike plates for rim and vertical rod devices normally are provided with either a toothed backer plate to hold the strike in place once properly positioned, or a round hole for drilling in a screw to fix it in place after adjustment. If the toothed plate or third screw is not installed, the strikes will loosen up and inhibit proper latching. This can lead to damage of the hardware itself. This is a very common installation problem and should be closely monitored during construction.

• Continuous Hinges: Continuous hinges contribute significantly to the longevity of the door hardware. At a minimum, continuous hinges shall always be specified at exterior doors.
• Through Bolts and Reinforcement: Both doors and hardware can fail due to inadequate reinforcement behind various door mounted hardware pieces or due to surface fastening instead of through-bolting. Although through-bolting hardware subject to lateral stresses may not produce the best aesthetic results, functionally it is far superior and will increase the life of the installation.
• Accessible/Automatic Entry Doors: Provide a coordinated effort in the design and the specification of the automatic door unit, the swing of the door leaf and the location of the wall mounted push actuator paddle which operates the door leaf for accessible entrance. The use of a pedestal mounted push actuator paddle shall be discouraged unless directed by CPS for a specific condition. Proper configuration of the automatic door operator and the door locking system interlocks will minimize premature failure of the system. Coordinate any requirements for an electric strike as part of the security entrance system on these openings.
• Accessible Access: A minimum of one door per building shall be designed as accessible, requiring a low- energy automatic operator (door operator). For buildings containing more than one school which have separate designated main entrances, or any building with multiple designated public entrances, additional accessible entrances shall be required.
  • Persons wishing entry during school hours pushes a button on an intercom and identifies themselves. If entry is permitted an electric strike shall be followed by operation of the automatic door opener and on a time delay basis the vestibule door opener will be activated, all by one push button.
  • Only one door at the main entry shall have an outside keyed lock, and all other exterior doors in this series shall have door pulls.
  • A separate exterior door at that same main entrance vestibule shall be provided with a keyed access, and exterior pull.
• Accessible Exiting is achieved by one (1) interior push button door release followed by a time delayed opening of the exterior door. The door shall remain in a fully open position for five (5) seconds, typical.

• Aiphone Entrance is achieved by pushing an outside Aiphone Door Station button. If entry is permitted, the door release is activated from the Administrative Suite, Security Guard Station(s) or Kitchen Office. Locations include but are not limited to:
  • Main Entrance door
  • ADA Accessible Entrance Door
  • The main building entrance closest to Staff Parking Lot
  • The main building entrance closest to Playground/Playfield and Athletic Sports Fields
  • The main building entrance closest to Annex/Modular Buildings
  • The entrance to each Annex/Modular Buildings
  • Food Delivery entrance adjacent to the Kitchen
  • Key Access: One door in the series of doors at every other entrance shall be provided with an electric strike and outside key cylinder access and pull for entry by persons having a key. Such doors include those for the purpose of 24/7 entry, including but not limited to, custodial entrance, kitchen deliveries and teacher’s entrance from parking lots.
    • Select exterior doors shall be provided with an outside keyed access and pull. Such doors can be unlocked from the outside by a person having the appropriate key or a person wishing entry may request it by intercom and release of the electric latch from the inside. Such doors include those to exterior temporary classrooms, gym doors to playground, and doors to trash compactors.
    • All doors with keyed access shall have pulls.
    • All other exterior doors shall not have exterior keyed access or pulls.
  • Security: All exterior doors shall have door contacts on the door head and door frame to alert, via a security system, that a door has been opened.
    • The intercom system, any associated camera, contactors and wiring to electric strike and automatic door operators is not provided with the hardware package and shall be coordinated appropriately.

• Continuous Hinges: Continuous hinges contribute significantly to the longevity of the door hardware. At a minimum, continuous hinges shall always be specified at stairwell doors, cafeteria and gymnasium/multi use room doors. The key is high use.
• Swing Clear Hinges: In a number of cases in the multi-use rooms (used as both gymnasium and cafeteria) where mats are hung on the wall adjacent to the door openings, the mats will prevent the doors (usually the servery doors) from opening all the way and engaging the magnets. This problem can be solved by using swing-clear hinges - an L-shaped hinge which brings the door out away from the wall when it opens. This solution can also be applied to wall-mounted accessories which receive wire-guards and cannot be otherwise coordinated to avoid the door swing.
• RENO Swing clear hinges are also a good solution for providing the minimum accessible doorway clear width in locations in renovation projects where a 34” wide door can’t be changed because of space restrictions or on corridor vestibule doors that need to be flush with the face of the door frame.

• Closers: with dead stops should not be used. Closers shall be spring-arm closers if a closer stop is required. Otherwise, specify one with no stop at all and wall stops or floor stops. Regular arm and parallel arm closers should have heavy duty arms equal to LCN “EDA” or Norton “HD”.
  • Door Closer Hold Opens: The reduction in wear on the heavily used doors, frames, and hardware at these openings may be significant. The doors requiring closers with hold-opens to be determined during the design phase.
  • Non-Fire Rated Openings requiring a hold open function shall have an electromagnetic hold open in lieu of a hold-open on the closer.
  • Interior Fire-Rated Openings cannot have the hold-open function on the closer and shall instead have magnets.
  • Magnetic Hold-Opens: This is the one device that is probably most responsible for the longevity of door hardware. Magnetic hold- opens are required on all stairwell doors, link doors connecting between buildings, horizontal separations in corridors, cafeteria doors, multi-use doors, gym doors, servery doors, and any other fire-rated doors that lines of students are routed through or are otherwise required to be held open.
  • Only magnets with substantial arms shall be used. If extensions are required, the box holding the magnet itself shall be extended, not the arm attached to the door. Low endurance magnets shall not be used. One type of magnet which shall not be used has a pencil width threaded rod holding the plate that engages the magnet. These rods, especially the longer ones, tend to break off within the first year. The electrical rough-ins for the electromagnetic devices are typically installed in advance of the door installation, the wall mounting location needs to be detailed in the documents for proper coordination.
  • Emergency Controls: Magnetic hold open devices shall be controlled by the building’s fire alarm control panel.
  • Back-box installations of the electromagnetic device in the wall need to have adequate support, preferably masonry grouted solid. If the installation must be in drywall , adequate blocking needs to be included and detailed in the design documents. Finally, the door frame, door, and magnet depth need to be coordinated both with the depth of the operating hardware and the wall location to ensure a full 90 degree opening.
  • Link Doors: The important thing here is the “A” label opening. These doors shall always have magnetic hold opens. An astragal shall always be used if it is a pair of doors not having a removable mullion, and the astragal should always be on the hinge side. Installations having the astragal on the opposite side of the door tends to hit the mortise latch on the leaf being held open with the coordinator). The typical arrangement of mortise lockset on one leaf with vertical rods on the other works reasonably well, however, this also necessitates a coordinator, carry bar, and strike in the floor, which tends to fill up with dirt. In very few cases does the rod actually engage in the floor strike.
  • A better and more foolproof arrangement for link doors would be a center mullion and rim device panics, thereby eliminating most of the fussy accessories. An argument could be made that the mullion actually helps direct traffic through the link area. However, to be effective as a traffic control device, doors with rim type panics and mullions should be 42” to 48” wide, and this may not always be practical. Because of the “A” label astragal requirement, these doors should NEVER have a pair of vertical rod exit devices with an astragal on one leaf. In this arrangement the astragal will hold the one leaf of the doors closed and will compromise exiting/access.
    • For a four (4) hour fire separation requirement, provide a series of two (2) ”A” label doors separated by a vestibule.
  • Door Pairs with Push to Exit Panic Device: Push to exit Panic devices shall be used based upon occupancy and exiting requirements, and is generally not specified purely for hardware function.
    • Low Use Doors: In a fire rated wall with a low use pair of doors where code requires only a single leaf with panic hardware for exiting, such as for mechanical rooms, the inactive leaf shall have automatic flush bolts to achieve automatic latching for the fire rating, and the active leaf shall have a mortise lockset. This pair of doors also requires a coordinator because of the mortise lockset.
    • High Use Doors: The configuration for a high use area pair of doors where code requires only a single leaf with panic hardware for exiting, shall be two top rod only panic devices, despite the fact that panic devices are not required for occupancy and exiting. This allows for the elimination of the flush bolts, mortise lockset, and coordinator in the hardware set. When classroom or other frequently used openings are configured as discussed above for low use doors only, the installation tends to fail due to the frequency of use. The automatic flush bolts either jam or stop working and the strike pieces for the automatic flush bolts tend to wear down and cease to extend the bolts properly. The doors then tend to be forced open or closed, stressing the hinges and resulting in the doors not sitting properly in their frames.
  • Strike Plates: Strike plates for rim and vertical rod devices normally are provided with either a toothed backer plate to hold the strike in place once properly positioned, or a round hole for drilling in a screw to fix it in place after adjustment. If the toothed plate or third screw is not installed, the strikes will loosen up and inhibit proper latching. This can lead to damage of the hardware itself. This is a very common installation problem and should be closely monitored during construction.
  • Through Bolts and Reinforcement: Both doors and hardware can fail due to inadequate reinforcement behind various door mounted hardware pieces or due to surface fastening instead of through-bolting. Although through-bolting hardware subject to lateral stresses may not produce the best aesthetic results, functionally it is far superior and will increase the life of the installation.
  • Stairwell Locksets: The current standard is to have lockable trim on the stairwell doors, that will allow the doors to be locked during evening functions to restrict access to the upper floors.
  • Overhead Coiling Fire Doors: Swing doors are preferable to overhead coiling doors at fire-rated openings. There are cases, however, where overhead coiling doors may be used with CPS prior approval, 196provided they are in a location that needs to be closed off only in the case of fire, and provided that they are properly coordinated with egress. A fire rated egress door to be located directly adjacent to each overhead coiling door for ease of access. The overhead coiling door is required to be tied to the fire alarm system at the fusible link. Considering cost and convenience, overhead coiling doors shall not be used in openings requiring access control and where hinge doors and magnetic hold opens can be used.
    • For a four (4) hour fire separation requirement, provide a series of two (2) ”A” label doors (overhead coiling and a fire rated egress door) separated by a vestibule.

Traffic direction, patterns and volume to be considered when reviewing and selecting proper doors and associated hardware. Door swings to follow the traffic flow including the use of double egress door assembly at the primary corridors. Lines of students moving down the stairs and corridors and through the servery and into the cafeteria at lunchtime set up definite one-way traffic patterns that should be considered in establishing proper exiting.
