Optima 2 Plus Zone fault


Litch90

Recommended Posts

Discovered an Optima 2 Plus panel today on my travels, went to do a full service for the customer.

 

When attempting to set, i had 6,5 & 2 on the visual display, obviously zone faults... However, i checked all cables, terminations & present voltage at the detectors.

 

All came back fine. What else could this be? The only thing I did not try today was replacement sensors (they are as old as the hills) 

 

I'll hold my hand up and admit I've seen this panel maybe three times so i'm not overly familiar with it. Any suggestions?

 

Thanks

you check the resistance of the circuits ?

Thanks for your reply bud

 

Across the three zones they were each giving something off in the ranges

 

0.6

0.12

0.8 

 

If i remember correctly.. what sort of readings would you expect on this system MH?

0.12 was indeed mooted just about half a metre from panel

 

0.66 was living room.. so about 4/5 metres from panel

 

0.8 is a tricky one.. mounted at least a good 10 metres away

 

What do you reckon? Belled the cores individually on the 8C comes back fine no damaged cores.

if the zones show open when the cicuit is closed

 

did you check resistance between alarm & tamper pairs ? (2+ had tamper per zone (IIRC))

 

Before changing any devices I'll link zones out & see if the panels goosed, it will on or around 25 yrs old ?
