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 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.
