Hi,

i have a problem with my security alarm system now. Frequently getting tamper alarm, I can clear it with security code, but comes back again in next cycle. How to remove this or how to solve this tamper alarm, Alarm log shows only tamper alarm . Could not find wher is the tamper alarm,, i think its in outside siren, but nothing wrong, alarm comes every 12 hrs I belive. Any solutions, please let me know.

From memory this happened to us once when the back up battery was going flat... Someone else may have more idea.

My views (except when I am looking out their windows) are not those of my employer.

There may be a tamper switch on the alarm panel as well as the external siren. When I've gone to check this kind of fault before, on the rare occasion it has been the outside siren with some temperature changes (contraction/expansion) - though I cannot imagine this at this time of year... Is the alarm panel closed off/screwed shut?

Sensors have tamper switches as well. They aren't always used, but if they are you should be able to find wiring for this inside the sensor and at the panel.

As alarms are usually active low, a bad connection somewhere can cause either the tamper or motion detection to trigger.

If the tamper alarm is coming on at 12hr intervals maybe it's a marginal connection combined with lower volts running on battery during a battery test cycle.
