OPTIMA 2 PLUS PIR IS NOT TRIGGERING ALARM

All door contacts chime.

All pirs chime in chime mode, hence working?

The problem started when my 11 month old son pressed some buttons on the keypad.

The alarm will set as if everything is ok.

Entry and exit zone 1 seem to work fine, but the alarm does not trigger when pir zones 2/3/4 are triggered, when the alarm is on. Has he disabled them some how? If so how can I enable them again?

Any help would be most appreciated many thanks

The detectors cannot be perminantly programmed out or isolated. How low is your keypad ? how tall is your son?

How are you testing the detectors? have you tried setting the system then walking infront of them?

Or it could just be the bell and internal sounder no longer works.

Yes, I have set the system, walked in front of the pirs, they just flash red, no alarm sound. When I go to deactivate the alarm, the zones are just lit up. Internal siren and external siren do work.

Many thanks

So the panel is indicating that the zones have activated then?

yes.

has he put it in test mode?

how can i fix it, please

It could be a few things. The sensor could be in 'double knock' which means they have to be triggered, cleared and then triggered again to activate the alarm.

Test it again with that in mind

.....Bell delay ?

or

Do the PIRs work if put in 'walk test' mode ? - (You should get a chime/beep from the panel when the PIR LED glows)
