SARGENT 57 - Delayed Egress - Manual (Page 4)

2 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.
