Why Does My EE Not Arm?
Be sure that the dead latch is being pushed in. If the strike isn't aligned properly, it may not keep the dead latch in.
If it arms while pushing in the deadlatch, the strike may need to be shimmed closer to the latchbolt.
If it doesn’t arm after pushing in the deadlatch, examine the plugs in the latch assembly:
Make sure the 2 pin connector is fully seated on both pins and the modular (phone type) is clicked in here and also at the main circuit board.

When I Turn The Key To Reset, Why Doesn't The Time Bar Display Reset?
All LED's and bar display are fully on reset by unplugging both modular cables and plugging the control board back in first, then the display board.
If LED's return to normal. Test by adding time and opening and closing door should reset the display. Opening the door should sound the alarm with no time entered. This would be working correctly.
Display has 1 bar and can’t clear. Reset by unplugging both modular cables and plugging the control board back in first and then the display board. If this doesn’t correct it then check to see that the micro switch being released. If it is released then Cycle power to reset, if no help. Replacement board kit is 104393. This includes all 3 circuit boards and the modular cable.
Why Does The Unit Chirp Every 20-30 Seconds?
Low battery indication.
Check AC power to the device for 24VAC plug-in transformer
If other then 24VAC replace with plug-in 103951
Battery should be replaced every 3-years
Battery backup 1-day fully charge
U-6 hot to the touch indicates bad battery or short in the wires
Why Does The Alarm Sound When Pushing The Button To Add Time?
Check the cam assembly arm that activates the Micro Switch. Is it staying up and not returning down?
Corrective action would be to loosen the two cam screws a bit they could be over tightened causing binding. If there is still an issue replace the cam (p/n 102680).
I Can't Add Time To The Bar Display
Turn the key counter clockwise to reset and release the key. Then push the time button to increment bar display.
If you hold the key in the reset position and don’t release it and push the time button to increment, the display will start to add time but will alarm every time the button is pushed.
Pushing and holding the button to add time the bar graph starts to increment part of the way and the alarm sounds. Also, pushing the button 1 step at a time sounds the alarm.
The cam lever is holding in the micro switch and not returning back down.
Corrective action would be:
Loosen the two cam screws a bit they could be over tightened causing binding. If there is still an issue replace the cam, part number 102680.
Why Is The Alarm Operating Intermittently?

Why Is The Device Not Arming?
The unit could be handed to the wrong side, or the magnet may be out of alignment.
Unplug battery and re-connect, if the unit beeps 5 times the unit is not handed.
Use the magnet locator when mounting the device.

Devices silent arming option is enabled. To turn off this feature:
Why Does The Device Go Straight Into Alarm After Arming?
May be set to auto rearm(non-extended bypass) and the magnet on the frame not aligned properly.
Re-hand the device and ensure door stays closed throughout entire arming process.
The Magnet Only Works On One Side Of The Device
Disarm the device by turning your key clockwise. Look on the circuit board near the sticker saying "500", there are two metal prongs with white lettering near them saying 'Mag Handing'. Short them together using something metal like a screwdriver or a key. The unit should beep 5 times. Reinstall the device with the door open, arm by turning the key counter-clockwise and close the door. You should hear 1 chirp and then the device should start the 15 second arming delay indicated by rapid flashing of green light, followed by 3 chirps, indicating that it is armed.
If JP1 is cut on the board, the unit is made to mount on the wall and use a external magnetic switch.
Please refer to the installation instructions for more information on how to re-hand your device

How To Install For A Pair Of Doors
The device mounts to the wall and 2 external magnetic switches need to be used. The switches are wired in series and connected to terminals 5 & 6. See diagram below:
Why Is My Device Going Straight Into Alarm?
Two possible reasons:
1. Tamper plunger is not being held back by the screw on the upper left of the front of the device. Make sure the unit is mounted and the top left tamper screw is installed. Check That the security plunger is engaging the security micro switch on the back of the PCB.
2. Set to auto rearm(non-extended bypass) and the magnet on the frame not aligned properly. Isolate the device by using a jumper to simulate the door closure in inputs 5 and 6. If your device works, then check you magnet switch continuity. The magnetic switch is a closed contact when the door is closed and opens when the door is opened. These two wires should be connected to terminals 5 & 6.
Why Does My Device Not Alarm When The Door Opens?
The likely causes are that either:
- Your door contact is not activating when the door closes. In this case, your device will not arm if the contact wires are removed from the device.
- Electric power was applied across terminals 5 and 6. In this case, your device will still arm after the door contact wires are removed from the device.
