Grade 3 bell box monitoring

[newuwave]

A question if I may on removing bell box.

I have planned to invoke "hold off" mode, then open the boxes, then come back to control panel and pull the +12V supply to the bell boxes, then back to bell boxes and pull battery jumper, then remove boxes.

 

Or can I invoke "hold off" mode, check right LEDs are flashing to be sure of hold off mode, then at control panel pull the +12V supply to the bell boxes, then open boxes and pull battery jumper, then remove boxes. 

 

I understand new boxes will stay in "hold off" mode until I connect +12v supply to the boxes, so I can make all connections in the new boxes, jumpers set to SCB and LC on then connect battery jumper and close boxes and finally connect +12V supply in control panel to the boxes.

 

Then I can test strobe and bell and alarm to see all is working ok.

"Using the test wire requires wiring as per Texecom recommendations otherwise you'll get faults on every test signal.

The panel has to be programmed to expect the test is happening if you use Zones instead of fault input."

 

I will look into the bell test wire method as you have kindly mentioned....I'll have to google this as I cannot recall reading any documentation on it.

 

Thanks again for the advice.

Using the Aux input the panel knows to expect the test if it's programmed at a fault and not a tamper, with a zone you'll have to program that zone attribute.

I'd do what I suggested in a previous post before taking anything apart to see if the fault will clear. I'm still sus it's not wired correctly somehow.

You should be able to disable them completely from the panel via the engineer hold off, yes.

ok - I will try what you suggest to see if the fault will clear. The 5E box right led only flashing has just started in this last week or so. Before that for 13 years its been like the Premier Elite Odyssey 3 with right and left leds alternate flashing.

 

Alarm worked as expected and no fault or false alarms. I've not tried to arm alarm since 5e showed flashing right led only.

 

But will look into it tomorrow as busy today.

 

Thanks again.

Looked at how to use Test input to bell boxes....but I read 24-W panel only has one programmable output and I'm already using this to trigger an external GSM that rings people when the alarm is triggered. So I guess I cannot do this.

 

Will try what you suggested to see if it clears bell 5E RHS flashing LED only.

"Try triggering the strobe and see if they activate, then just the bell trigger and see if it clears hold-off."

?

 

8 outputs on the side of pcb

2 output on the bottom of the pcb

ok - Thanks - will look into this.....I thought they were only for a stand alone communicator.

I take it an unactivated output is floating or 12v and pulls to 0V when activated and the 100mA exceeds the requirement to activate the Test on the bell box?

Looking at my notes from 13 years ago I have my boxes wired as this.....

 

But I am not using Aux/Fault to monitor tamper but am doing this....

 

 

and I did not use an output to carry out Test I guess because manual cites auto self test every 24 hours.

 

The test input can be used to invoke a remote sounder test, this performs the same functions as the self test which is carried out once every 24 hours. To invoke the test the input must be placed at 0V for a minimum of 60s, during this time the Fault relay will open to signal the test is in progress. On completion of a successful test the Fault relay will close, if the test fails the relay will stay open.

I recall 13 years ago it took me quite a few days to digest manuals, install and program the kit as it is quite complicated and hence taken me some time to refresh what I'd done. So today up the ladders I go to change the bell boxes to have some confidence in their reliability ....bit wobbly these days as an OAP approaching 70 so will take it easy.

Thanks for the help.

One last thing. I mentioned earlier...

I understand new boxes will stay in "hold off" mode until I connect +12v supply to the boxes, so I can make all connections in the new boxes, jumpers set to SCB and LC on then connect battery jumper and close boxes and finally connect +12V supply in control panel to the boxes.

 

I read this is incorrect. Procedure should be...

 

I understand new boxes will stay in "hold off" mode until I connect +12v supply to the boxes, so I can make all connections in the new boxes,  connect Battery Jumper first so unit will enter Hold Off mode, then set to SCB and LC on  and close boxes and finally connect +12V supply in control panel to the boxes.

It does say that in the manual. I can't see how it functions the same, especially when one does a functional test of the relay output and the other doesn't....

 

Makes no difference for the last post.

Good point about relay.

I guess I can bring each test wire back to loft JB and just leave them on oc terminal rail.

Log on in Engineer mode to view event log,  test leads (reading voltage maybe?) on the relay output connected to terminal rail then test each at a time by linking it to 0V for minimum of 60 seconds with a wire.....

 

I wonder if the relay event is logged ....could use this to see results.

 

Thanks again.
