hi guys i had some call outs to a site which we took over they have three loops on a zeta panel however they started getting devices come up wrong type?and once they do you cant clear it by re learning or powering down.it starting to become frequent with the smoke detectors.but inside these detectors are apollo!any ideas whats wrong?seems like corrupt data.many thanks in advance

Same loop?

Same loop?

the first 2were loop relays on loop 2

all the rest have been smokes on loop 3.

Earth faults?

Sounds like works being done and they have damaged a cable.

Ask cerbs, he is the fire Expert here.

on loop 3 the earths were never terminated in the panel!but all the others were it was a rushed job by a large firm.and the owner is tight so doesent want the investigation time!could the lack of earth be an issue?

Deffinatly.

If its cross bonded it could cause several issues.

Again Cerbs is the man, but I feel he would agree.

cross bonded?could you elaborate on that one for me?

i would imagine also as the system was installed by an electrical firm they prob linked fp earth with powes supply earths!see this all the time with sparks

newy & arye thing ?

thanks for the reply.

yea its the premier al4.

its a **** panel but very easy to use i learnt it all without any manuals.

its only slightly harder to set up loop relays as they dont work even when there learnt on you have to set up the zone and output type which wasent as straight forward as it could be!
