My wife and I recently moved into a rental house in Ecuador. There’s been a drought here, so power outages are scheduled. It’s manageable, except for the house’s security system. Every time the power comes back on, it starts beeping every 6-8 seconds. To stop it, I have to arm and then disarm the system, which happens three times every morning around 6 a.m. It’s really annoying.
The house has other security features, and we feel safe in the area, so we just want to turn this system off temporarily. I found out it’s a DSC PC1555RKZ system and got the manual here:
On the wiring diagram page, I saw the first two contacts are for 120V AC power. If I meter them, figure out which is ground, and disconnect it, will that shut the system down? Appreciate any help!
To completely turn it off, you need to disconnect both the battery and the main power. The battery is inside the panel—just pull out the red and black wires. For the power supply, look for it plugged into an outlet near the panel. It’s usually pretty big but sometimes hidden. You might need a screwdriver if it’s secured to the wall.

Thanks! I got the battery disconnected. The power supply turned out to be inside the panel with the wires wrapped around the contacts. Wiring here is… interesting. I removed and taped the wires, and now when I turn the breaker on, the system doesn’t power up.
For something more convenient long term, you could add a key-operated switch to turn the system on or off. You could also do the same for the battery circuit. Just hide it somewhere clever.

A DPDT key switch could handle both circuits with one switch. Makes it simpler.
