My Optima G4 panel sets ok on exit when leaving the premises, however on entry the alarm is activated before you can enter its key code. When you view the panel leds 1 and 2 are on and 3 is flashing. Zone 1 has just the entry/exit door on it and a pa button, Zone 2 has three pirs one in the bedroom and 2 in the hallway which should be inhibited but they appear to activate the alarm on entry? Zone 3 has two pirs in other rooms which are not in the E/E route plus a couple of door contacts. All the circuits have been tested seperately for continuity and resistance no problems there. So why does the panel let you set it on exit ok but not isolate it on re-entry ?

The magnetic door contact is faulty therefor when you open the door, zone 2, the hall, is not inhibited causing the alarm to go off.
The magnetic door contacts are either surface mounted or flush mounted into the door, are easy to change and cost about £1 each from TLC if you have a branch near you

Oh dear, I think you should go back and read the book.

1. You can't have a door contact and a PA button on the same circuit, they work in a completely ways

2. etc etc

3. I really don't know what to say, this is the wrong place to try to sort all this out. Have a look for www.thesecurityinstaller.co.uk and their DIY Forum
