Friedland wireless alarms are provided to customers throughout the United Kingdom and Europe. These alarms operate by sending signals across radio frequencies. Most wireless alarms use the 433MHz frequency. Friedland uses the 866MHz frequency, which is less crowded. If you find there are problems with your wireless alarm system you don't know how to solve, attempt to troubleshoot them on your own before contacting customer service.

Check to see if the siren is in "Service Mode" if the siren will not respond to the remote control or the keypad. If so, it needs to be switched to "Operating Mode." Your owner's manual has instructions on how to do this. Ensure that the batteries in the remote control or keypad are not running low. Verify that the siren has learnt the "ID Code" of the detector. Check that the correct user access code was entered.

See if the siren tamper switch is activated if your siren sounds immediately after the system is armed. Ensure that the switch fully closes when you mount the siren by adjusting the tamper plunger. Excessive unevenness of the wall may cause the switch to not close properly. Relocate the siren to a more desirable location.

Ensure that the detector tamper switch is not activated if your siren sounds while the system is disarmed or if it goes off when nothing, such as an intruder, has triggered it. Verify that the battery covers of the detectors and keypads are securely in place. Make sure the "Personal Attack Alarm" is not being operated from the remote control or the keypad.

Check to make sure the battery is in place, facing the correct polarity, if the LED on the remote control is not illuminating. Verify that the battery holder connections are making proper contact with the battery. Ensure that your battery is not low. If it is, replace it.

Make sure the detector is not directed at a source of heat or a moving object if the PIR Movement Detector is falsely alarming. Do not mount the detector above a radiator or a heater. Be careful to not have it facing a window or pointing into the direct sunlight. If these steps do not solve your problem, check to see that the sensitivity is not set to High. If it is, reset it to Low.
