Spotlight On… Fire-Alarm Controlled Door Hardware Gerry Atkin, AHC Doors do more than just open & close... they provide safety, security, and accessibility. Codes NFPA 80 Fire Rated Doors and Windows NFPA 101 Life Safety Barrier Free NBC / OBC Ontarians with Disabilities Act 2006 NFPA 80 2007 Edition Fire Door Inspection Requirements NFPA 80 (2007) – NEW SECTION 5.2 - Inspection 5.2.1 Fire door assemblies shall be inspected and tested not less that annually, and a written report shall be signed and kept for inspection by the AHJ A basic electric circuit has 4 components. 1-Power Supply 2-Switch 3-Conductor 4-Load 2 1 3 4 Power Supplies Power Supplies Power Supplies Hardware for Fire Doors Problem • Fire doors must close with closer • Cross corridor doors are fire rated • Owner wants doors to be held open Solutions wall or floor magnet with closer electro-magnetic hold-open closer battery-operated detector holder with closer non-detector holders must be wired into the fire alarm system • stairwells - all doors must close simultaneously • • • • Acceptable Ways to Hold Open a Fire Door • wall or floor magnet with closer Acceptable Ways to Hold Open a Fire Door Closing Device Fire-rated openings require a closing device to ensure the door is kept closed fire rated, non-petroleum, hydraulic fluid may be required Fire-rated openings can be held open only with listed closing devices, provided they: Release upon signal from alarm system Integral to closer / fail safe door holder Acceptable Ways to Hold Open a Fire Door • Electro-Magnetic Hold-Open Closer • Single Point Hold-Open (SE) • Multi-Point Hold-Open (ME) Un-Acceptable Ways to Hold Open a Fire Door Problem • Fire doors must close with closer • Owner wants doors to be held open Other locations may include: Theatre exit doors Storage room doors Shipping / Receiving areas Elevator Lobbies Office Suite entry Problem • Fire doors must have positive latching • Owner wants free “access” during fire Buildings over a certain number of floors must provide re-entry every 5th floor allowing access to second stairwell. Office buildings pose additional security issues. Solutions • • • • Electrically controlled access from stair side Must be fail un-locked Controlled by security system Un-locked by the fire alarm system Solutions Electric Locks • Electrically controlled trim • Two options: Electrically LOCKED Electrically UN-LOCKED Solutions Electric exit device trim • Electrically controlled trim • Two options: Electrically LOCKED Electrically UN-LOCKED Fail Safe vs. Fail Secure • Fail Safe - When power fails, the door is un-locked or un-latched • Fail Secure - When power fails, the door remains locked or secure Electric Strikes • Replaces standard strike for lockset or exit device. • Keeper secures and releases latchbolt. Problem • Fire doors must have positive latching • Owner wants a “push-pull” operation In certain locations such as theatres and banquet halls exit doors make a lot of noise and would function better if they could just be PUSH and PULL Solutions Electric exit device with latch retraction • Electrically controlled latch • Two options: EL - Solenoid QEL – Motorized EL devices can be used to hold the latches retracted on fire doors if they are connected to the fire alarm system. EL devices can be used to hold the latches retracted on fire doors if they are connected to the fire alarm system. LIFE SAFETY Problem • Exit door are required due to occupancy loads • Owner does not want people to use exits In certain locations such as art galleries or public libraries require several exits – but they are for “emergency” only... Or there are security requirements that need authorized egress Delayed Egress Locks • Designed to delay egress to prevent theft. • Must allow egress for life safety. • Typically a delayed egress exit device (Chexit) or magnetic lock with delayed egress controller. Delayed Egress Exits • 15-second delay(30 seconds IF approved by AHJ) • 30-second relock per BOCA, manual relock per NFPA 101 • No delay when fire alarm sounds or upon loss of power • Audible local alarm • Signage - “Push until alarm sounds. Door can be opened in 15 seconds.” • One delay maximum per means of egress. • Not allowed in all occupancies. Controlled Egress Doors • Sensor on egress side to unlock when approached by an occupant • Unlocked by loss of power to sensor or lock. • Manual release device (push button) on egress side with signage. Remains unlocked for 30 seconds min. • Unlocked by fire alarm or sprinkler system until system is reset. • Prohibited on entrance doors in Use Groups A, B, E, or M while open to the public. Solutions Exit device with delay egress • • • • • Electric Latch Retraction Electric Dogging (push-pull function) Electrically Operated Trim Exit Alarm or Request to Exit Delay Exit (where codes permit) Controlled Egress Doors (restricted egress) Controlled Exit Doors Problem • Doors are card access with “inter-lock” • Must be fail locked (ingress) and fail safe egress Bio-Hazard, Forensic Lab, Drug-Labs etc., Bank sorting centers, Museums or Art galleries may have doors that can only be opened one at time creating inter-lock doors or man-traps Solutions Electro-magnetic Locks Mag-Locks can be used (where codes permit) to control ingress and/or egress, or to enable a inter-locks doors Solutions Mag-Locks for inter-locking doors Controlled Egress Doors • Used to control and monitor ingress & egress. • Must also provide life safety. • Typically an electro-magnetic lock and card reader or keypad. Electromagnetic Locks • Always Fail safe • Direct Hold (surface mounted) • Shear Locks (concealed) Questions & Answers
