California Building
Code Compliant
KEEP PUSHING. THIS DOOR WILL OPEN
IN 15 SECONDS. ALARM WILL SOUND.
Application
When unauthorized egress is initiated, the Exit Check® delays egress through the door for a period of 15 seconds.
Meanwhile, the person exiting must wait allowing personnel or security respond. The door unlocks after the 15 second
delay period has elapsed, permitting egress. A signal from the fire/life safety system will release the lock immediately
for uninhibited egress in an emergency.
Exit Check® applications include:
 Restricting the egress of patients for their own safety.
 Restricting the egress of commercial center patrons for minimum security application needs.

INSTALLATION INSTRUCTIONS

P:\INST INSTRUCTIONS\DELAYED EGRESS\INST-1581S REV F2 12-22 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 status LED is solid green.
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 / Bypass 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 or the door closes, the Exit Check will
automatically relock.
By keeping 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.
(BOCA/Chicago)
The 1581S operation complies with
BOCA National Building Code and
the Chicago Building Code: UL
Listed, Special Locking
Arrangements and Auxiliary Locks.
Per BOCA compliance, the Exit Check is manually reset by authorized personnel after an alarm by closing the door and
actuating the integral reset key switch or by momentarily closing a contact connected to the remote reset terminals. In
addition, reset will be automatically initiated once the door has been opened, then closed and remains closed for 30
consecutive seconds.
(NFPA-101)
The 1581S operation complies with
the following building and fire codes:
NFPA 101; NFPA 1-UFC; UBC; IBC;
IFC; SBC; California Building Code.

Door and Frame Preparation Instructions
STEP 1. Locate the paper template and fold
along the dotted line. Place the folded edge of
the template against the door stop and door at
the header while against the vertical stop,
opposite the hinge side of the door. Tape in
place at this position.
STEP 2. As indicated on the paper template,
punch the designated hole locations on the
frame and armature mounting holes on the door.
(NOTE: PRIOR TO DRILLING, INSPECT TO SEE IF
ANY OF THE HOLES CANNOT BE DRILLED DUE
TO THE FRAME OR DOOR CONFIGURATION. A
FILLER PLATE OR ANGLE BRACKET MAY BE
REQUIRED. SEE PAGE 5.)
STEP 3. Drill and tap the two 1581S mounting
holes as indicated on the paper template.
(NOTE: READ NOTE ON TEMPLATE WITH
REGARD TO SELECTING THE PROPER HOLE

STEP 1. Mount armature to door. (See figures
2A, 2B & 2C.)
STEP 2. Install the mounting plate (filler plate
and/or angle bracket if needed – see figures 1A,
1B & 1C) to header with only the two screws at
the slotted hole locations at this time. Snug the
screws down lightly (do not torque) so the
mounting plate & lock can be repositioned later.
STEP 3. Temporarily install the lock to the
mounting plate with the 1/4-20 socket head
screws encased in the lock.
STEP 4. With the lock mounted, close the door
so the armature just comes into contact with the
face of the lock. If the door is not completely
closed as the lock & armature touch, open the
door and reposition the lock away from the door
as described in step 2. (THIS IS TO PREVENT
THE DOOR FROM USING THE LOCK AS THE
DOOR STOP.)
STEP 5. Remove the lock from the mounting
plate, mark & punch all remaining screw and
wiring holes. Drill & tap holes as indicated on the
paper template and install all screws.
STEP 6. Reinstall the lock to the mounting
plate. At this point, if there is no need to remove
the lock for painting or any other reason, install
the anti-tamper plugs over the socket head
mounting screws, using a soft hammer to avoid
damage to the lock case.

STEP 1. After the lock has been mounted to the door and frame per the provided template, make all wiring
connections to the lock. At a minimum, this will be the power and reset inputs (black, red & blue conductors). It is
important that the reset input (blue conductor) be connected to a normally open momentary, dry contact switch (i.e.
928 Digital Keypad or 728 Key Switch) for initial setup adjustments as well as to reset the lock to a secure status
after it has been activated.
STEP 2. With all wiring connections completed, re-install the lock cover onto the lock. Ensure that the trigger
sensor is aligned with the hole in the cover. The sensor is preset at the factory to slightly project through the cover.
WARNING: DO NOT ATTEMPT TO ADJUST THE TRIGGER SENSOR LENGTH. AS THIS WILL RESULT IN DAMAGE TO
THE SENSOR AND VOID THE WARRANTY.
STEP 3. Slowly swing the door closed and visually observe the position of the armature trigger as it approaches
the trigger sensor on the lock. If the provided mounting template was used during the lock and armature installation,
the trigger & sensor should align with one another both horizontally and vertically. IMPORTANT: CORRECT
OPERATION OF THIS LOCK DEPENDS ON THE TRIGGER SENSOR BEING ABLE TO DETECT THE TRIGGER WHEN THE
DOOR IS CLOSED. A PROXIMITY ADJUSTMENT CAN BE MADE TO THE TRIGGER FOR FINE TUNING. THIS IS
EXPLAINED IN STEP 4.
STEP 4. NOTE: BEFORE STARTING THIS NEXT STEP, YOU WILL NEED TO BE ABLE TO ACTIVATE THE ALARM
RESET INPUT. After alignment has been verified, close the door and ensure DIP switch #2 is OFF. Apply power to
the lock. Push on the door. The LED should be flashing green, indicating that the lock is in the Manual Power Up
mode. Reset the lock at this time. The lock should now secure the door and the LED should be steady green. You
may change the mode to Auto Power Up by setting the #2 dipswitch to the ON position. Now when you first apply
power, you will see a solid green light and the door will be secure without having to reset the lock.
STEP 5. Activation of the 1581S can be made by door movement or an external trigger. When using the door
movement method, activation is achieved through the way the armature hardware is designed. When someone
unlatches the door and applies up to 15 lbs. pressure, the lock will hold onto the armature while simultaneously
letting the trigger/door move away from the lock/trigger sensor. Sensitivity in the detection of the trigger movement
can be adjusted for optimum sensitivity & performance. This adjustment can be made by using the 5mm hex
wrench provided with the lock. The center of the trigger or “target” is spring loaded and can be screwed in and out
of the armature thus either decreasing or increasing the space between itself and the sensor. The “spring” feature
of the target is to prevent damage from direct contact with the trigger sensor. Depending on the accuracy of the
alignment, the trigger does not have to physically touch the sensor to operate correctly.
