Bellbox Cover Tamper

[Guest Damian W]

Is it possible to wire a bell box (Flashgaurd in this case) to it's control panel (Accenta G3 in this case) so as, when in engineers mode, it is possible to remove the bellbox cover without causing a tamper activation and thus causing significant discomfort to ones self? i have read several posts on the subject which appear to fuel only engineer rivalry. Please, is there a standard way of accomplishing such a thing. I used to fit alarm systems for a small business in Accrington for several years and my then boss (alarm guru!) never taught me how to do such a thing if indeed it be possible?

I have just fitted a new super-duper system to my new house which is now live but need to connect the backup battery jumpers in the bellbox on the PCB (didn't do it on installation just in case I had any teething problems and needed to hush the thing!)

ALSO, I appear to have a fault on my (global) tamper circuit. Have tested the cables at the panel end with a continuity tester and all seems well with virtualy no resitance across the 4 pairs (connected in serial). Yet when I remove the staple link from the TA terminals and connect the two ends of the tamper circuit the panel genrates a fault which requires in the continual entry of the user code to silence the alarm when attempting to return it to day mode from engineers mode. If I put the staple back in the terminals then all is well again! Any ideas?

Many thanks,

Damian

no...

open bell tamper = ring ring

gobal tamper prob is a maybe short between alarm & tamper... (closed on meter open on panel)

No idea if there's a standard way, but I had the same thoughts when installing my Accenta G3. Not with the same bellbox though.

I commissioned the alarm (without bellbox battery) then read the installation manuals VERY CAREFULLY.

I did what I thought was correct (can't now remember what exactly), put on my ear defenders, and went up the ladder.

Took off the cover, connected battery, put cover back carefully (checking tampers were correct). It didn't go off.

Back on the ground put it all back to normal and tested OK.

So, it might be possible, but I wouldn't take the risk - wear ear defenders.

The only way you can do this would to be to use a bell box with an enginner's hold off function. The only two manufacturers I can think of that offer such a product are Texecom and Elmdene. Either that, or just use a pair of ear defenders! I normally connect everything up in the bell box, place the bell box timer in test mode (usually by moving ajumper link. The flashguard should have this feature, check the manual), connect the battery, which will activate the sounder for the test time period (about 5 secs). The sounder should remain silent now. Take the bell box timer out of test mode, replace the bell box cover, and connect the supply at the control panel end.

You could swap the 0v hold off and tamper return wires around, that has the desired effect on most boxes.

MANY THANKS EVERYONE FOR YOUR ADVICE. ENDED UP GOING DOWN THE EAR DEFENDER ROUTE!!

TAMPER FAULT WAS A SILLY MISTAKE ON MY PART AS WHEN I CHECKED THE PIRS FOUND ONE OF THEM TO BE CONNECTED WRONG. I HAD WIRED THE TAMPER CIRCUIT ACROSS THE ALARM TERMIANLS (N.C) AND VICE-VERSA!

ONCE AGAIN, THANKS ALL & WARMEST REGARDS - DAMIAN W
