Mounting:
The SD-7428-GSEQ allows for a controlled exit from a room protected by an electromagnetic
door lock. To exit the room, press the large green button until the built-in buzzer sounds, at
which time a programmed pre-exit delay timer begins. After the delay, the door unlocks and
stays unlocked. To relock the door, use the included keys to turn the keyswitch.

Sample Application:
Delayed exit from a building:
Power
supply
Strobe light
Electromagnetic lock
1. An electromagnetic lock, such as the E-941SA-1200, is connected to the lock relay output.
2. A strobe light, such as the SL-1301-BAQ, can be connected to the remote alarm relay output.
This device will signal at a remote location whenever the remote alarm relay output is triggered.
Adjusting the Pre-Delay:
The pre-delay can be adjusted using the potentiometer located
on the circuit board. The pre-delay timer can be adjusted from
1~30 seconds. This sets the duration of time between the end
of the nuisance delay and when the door will unlock.
Adjusting the Nuisance Delay:
The nuisance delay determines how long the push button must
be activated before the pre-delay timer will start. The nuisance
delay can be programmed from 0~3 seconds.
NOTE: The nuisance delay is preset to 3 seconds.
Example:
Set to 0 seconds

Remote Alarm Relay Output:
The SD-7428-GSEQ is equipped with a 3A@30VDC Form C dry relay output for a remote alarm.
The remote alarm relay is normally energized.
A remote device or alarm connected to this output will be triggered at the start of the
pre-delay timer.
The remote alarm output will continue signaling until the keyswitch is turned on momentarily.
In the event of power loss, the remote alarm relay will de-energize to trigger the remote alarm.
Troubleshooting:
Request-to-Exit Button will not
release the lock
Check the nuisance delay (see page 3)
Check the pre-delay timer (see page 3)
Door will not relock
Turn keyswitch to re-energize lock relay
