General Description
BC-Prefix Option
The BC prefix for 57- indicates that the unit has been programmed to comply with the section of the BOCA code
relating to delayed egress.
BOCA allows for automatic reset of the delayed egress unit. Under BOCA, the unit can automatically reset thirty (30)
seconds after the door has been cycled. If the door is opened any time during the thirty (30) seconds, the timer in the unit
resets and waits another thirty (30) seconds before rearming. This requires a door position switch.
Note: If a door position switch is not used (Blue wire connected to Black wire), the unit will automatically reset in
30 seconds.
There are no user serviceable parts on the 57- PCB module assembly.
Electrical Specifications
The SARGENT 57-Delayed Egress Exit Device is designed to work with an external electromagnetic lock in
areas that require a delayed egress which alarms at the door when any attempt is made to violate the door.
The 57- device can be tied into a fire alarm system.
NOTE:
Proper connections and appropriate peripheral hardware are required.
All components must be installed according to prevailing electrical codes.
