Howdy,

I recently purchased a property with one of these alarms. Supposedly the previous owner never used it and has no info on it.
I am trying to get it into installer mode so I can reset it back to factory defaults and start getting it working.

I've downloaded all the manuals including the technician and installers manuals and nothing works.

I've tried unplugging the battery and turning power on/off with and without the tamper switch on.

It always comes up with Stay on and never goes into installer mode.

PLEASE can someone tell me how to do this.

Many thanks.
