P:\INSTALLATION INST\Delayed Egress\INST-1581S\INST-1581S.vsd REV D7 03-13 Page 2
1581S Operational Description
The door is closed and secured by latching hardware. The model 1581S Exit Check locks the door in the secured
position, and the display shows the unlock delay time.
Activation / Alarmed Release :
Activation of the 1581S Exit Check’s 15 second unlock cycle is started by releasing the door latch and applying up to
15 lbs. of pressure to the door causing slight door movement. A short nuisance delay period is then initiated, a pre-
activation warning tone is sounded . To prevent false alarms, re-latching the door during the nuisance delay period will
silence the pre-activation warning tone and keep the door locked.
Once the nuisance delay period has been exceeded, the Exit Check continues with an irreversible door release cycle.
The integral digital countdown display and voice commands continue to inform the person intending to exit of the
seconds remaining until unlock and an alarm output is activated to alert personnel of an unauthorized exit. After the 15
second delay cycle has expired, the Exit Check will release the door allowing free egress.
Reset / Relock:
The Exit Check can be manually reset by authorized personnel by closing the door and activating the Reset input.
Request to Exit / Authorized Bypass:
Momentarily actuating the Request to Exit input will initiate the request to exit cycle and unlock the 1581S Exit Check
allowing free egress. After the request to exit cycle has expired, the Exit Check will automatically relock.
Leaving the Request to Exit input continuously activated, the 1581S will remain unlocked for extended periods of time.
Releasing the Request to Exit input will restart the request to exit cycle and will relock the door after the request to exit
time has expired.
