If your Qolsys system will not arm because a door, window, or other sensor shows Open, first identify exactly which sensor is preventing normal arming.
These instructions apply generally to:
Look at the Qolsys panel for the exact sensor name.
For example:
Do not assume which opening is causing the problem.
Go to the opening identified by the panel.
The sensor should normally return to Closed.
If the door is physically closed but the panel still shows Open, inspect the alarm sensor.
Many door and window sensors use:
The sensor and magnet need to be positioned correctly when the opening is closed.
Look for:
Do not permanently reposition the equipment yourself.
Doors can change alignment because of:
A door may appear closed while the sensor and magnet are no longer close enough to operate correctly.
If pushing or pulling on the closed door changes the sensor status, contact CommTech Systems.
Make sure the window is completely closed.
Some windows can appear closed while remaining slightly open.
Check that:
If the problem began after replacing the sensor battery:
If the sensor still shows Open, contact CommTech Systems.
If the same sensor also reports Low Battery, address the battery condition.
A weak sensor battery can cause unreliable operation.
Use the correct battery for the specific sensor model.
Open and Tamper are different conditions.
Open normally refers to the state of the protected door or window.
Tamper normally refers to the sensor's enclosure or mounting.
If both are present, check that the opening is closed and that the sensor cover is installed correctly.
If the sensor also reports Malfunction or Not Responding, there may be a communication or device problem.
Contact CommTech Systems if normal checks do not correct it.
If the panel switches between Open and Closed when you push, pull, or move the door slightly, the sensor and magnet may no longer be aligned correctly.
Do not rely on pushing the door into a certain position every time you arm the system.
Contact CommTech Systems so the opening can be checked.
If the sensor or magnet has fallen off:
Do not assume that simply placing the magnet near the sensor is a permanent repair.
If several doors or windows show Open:
If multiple sensors incorrectly show Open, contact CommTech Systems.
If an ordinary burglary sensor has a problem, the Qolsys panel may provide an option to temporarily bypass that sensor when arming.
A bypassed sensor will not provide its normal protection.
Only bypass a sensor when you understand which device is being bypassed and the opening itself is secure.
Have the sensor repaired as soon as possible.
If you do not recognize the sensor name, do not bypass it simply to make the system arm.
Contact CommTech Systems so the device can be identified.
Do not use bypassing as a routine solution for:
Contact CommTech Systems if life-safety equipment is preventing normal system operation.
If the system arms after bypassing the problem sensor, that does not mean the sensor has been repaired.
The bypass simply allows the remainder of the applicable system to arm without normal protection from that device.
The underlying sensor problem should still be corrected.
If a sensor that previously showed Open begins working again without anything being repaired, the problem may be intermittent.
Intermittent sensor problems should not be ignored.
Record the sensor name and contact CommTech Systems if the problem returns.
Do not delete an open or malfunctioning sensor from the Qolsys panel simply to make the system arm.
Deleting the sensor can remove security protection from that opening.
Do not factory reset the Qolsys panel because a door or window shows Open.
The affected opening and sensor should be diagnosed directly.
