Intruder fault help!

[JCJ]

Hi guys, can anyone help me out with the following.

 

I have an accenta compact. My problems first started with zone 1 which is a PIR.

The keypad was showing the zone 1 LED and the internal sounder was producing a rapid tone. This was preventing the system being armed. 

 

I joined through the the alarm and tamper pair in the PIR and the above stopped and I could arm the system. So I replaced this PIR. The system then allowed me to arm.

 

However, the following day external siren was activated but There was no indication as to what caused the alarm. 

I then had trouble silencing the external sounder. The system would even allow me to arm it while the sounder was still

sounding.

 

I undid the bel box to find a couple of fairly loose connections. I tightened these but now the bell box does not trigger. But. If I remove the fuse in the panel then the sounder operates via its batteries. 

 

Can an anyone point me in the right direction so that I can get things back up and running? 

 

Thanks in advance!!

Faulty bell, bell tamper or loose tamper in the bell

Thanks for the reply. 

 

The tamper connection was loose when I opened up the bell box. All connections are now tight.

 

what is the best way to test to clarify to root cause?
