Opening an SAB

[Guest Gman]

Hi, great site, lots of usefull info.

I have a Scantronic 9448+ driving a CEQURA 2 SAB on the front of the house. I have all the user manuals and engineer codes so can disable the system to do walk tests, measure battery charge/discharge volts and change programme options at the control panel.

My question is, when my panel is in engineering mode, will this also disable the CEQURA SAR, I would like to check its battery, but dont want it going off in my ear when Im up a ladder!

Thanks

No, the sounder will activate whether the panel is in engineering mode or not.

Get a pair of 'ear defenders' from a hardware store or DIY store.

Oh and if you like your neighbours then get them a pair too!!

Or better still check the battery from the control panel.

Many thanks for your replies, I had a feeling this might be the case. I've already got ear defenders on my hard hat, so no need to go shopping!

Peter, do you mean that if I measure the SAR hold off volts in my panel, that will give me an indication of the state of the SAR battery? Should I disconnect them and measure with the sounder going? (Neighbours will love that).

One other question, if I connect the SAR tamper return wire to 0 Volts, would that stop the SAR tamper switch from operating if I open it up?

Thanks again.

No, Pete means disconnect the hold off voltage to the bell box and see if it sounds off it's battery, look at the diy servicing guide on the main site for instructions.

the tr wire is 0volts

Thanks Bellman,

Will give it a try and see if the battery is up to it. I did look at the maintenance advice, but could not see much about checking SAR battery. As a matter of interest, do you pro's check SAR battery operation as part of a routine service, or do you just change the battery at set intervals?

It also says in the CQR blurb that a battery fault will show as a simultaneous flash of the green LEDs on the beast. Mine are flashing normally (alternately), so is that a good enough indication that all is well up there?

i'm lurking here too, is anyone going to anwer this one?

Yes. Testing the SAB is part of a routine inspection.

I pull the +H wire out of the panel to see if the SAB/SAS battery is dead or not on a routine.

Thanks all,

Pulled my hold off +ve wire, and my SAB works big time! I would suggest that DIY maintainers do not do this unless they have full control/documents for their pannel. If in doubt, call a pro. and get them to check it.

p.s. Your advice was much appreciated.
