Rissy Posted October 31, 2017 Author Posted October 31, 2017 (edited) I have another question. What is supposed to happen if the alarm is armed, and the mains power to the system (house) is lost? Is the system supposed to still sit there silently until the house is illegally interfered with? I'm presuming this is the case, as what would be the point in the 12v battery backup....? I know that when the alarm ISN'T armed and the mains power is withdrawn, the alarm box still sits there silently and only makes noise when you open up the controller box.

The mains is constantly charging the battery and the battery is what is powering your system, if the mains fails the battery continues to power your system. Depending on the current being drawn by your system and the size of the battery, it should last anything between 6 and 12 hours. Professional installers will use a multimeter to find out what current is being drawn, and calculate what size battery is required to provide a minimum of 12 hours standby. 1 Quote

Thank you very much for all your help. It's great to finally get some extra clarity on the system i have. I really appreciate you helping me. :-) Quote

I still don't know which negative wire i need to pull for testing the bell box alarm properly.... out of the possible terminals named as follows, which is it we're talking about me needing to pull? ST- Strobe switched negative trigger. S - Sounder switched negative trigger + Sounder hold off/strobe positive supply. - Sounder hold off supply & sounder tamper feed (negative) -R Sounder tamper return. (negative) Also, do i want to do this with the alarm in an armed standpoint, or can i do it unarmed? If only armed, then how do i do this with the control box open? just tape down the tamper switch on the control box door? Quote
norman Posted November 1, 2017 Posted November 1, 2017 - Sounder hold off supply & sounder tamper feed (negative) Unarmed, this will kill the supply to the sounder and will/should prove the battery Quote Nothing is foolproof to a sufficiently talented fool.
datadiffusion Posted November 1, 2017 Posted November 1, 2017 Though it will only prove the battery is getting power to the right part of the bell circuitry, (esp. if it's just been replaced), it won't necessarily prove the charging side of the bell is working. Quote So, I've decided to take my work back underground.... to stop it falling into the wrong hands
