Connect 2nd siren box

Rudie · Feb 4, 2013

Hi,

I have 1 front siren box and am considering connecting a second siren box at the rear. Can i feed a wire from the current siren box terminals to feed the new 2nd siren box?

Thanks.

just parallel up the +12V, trig -. then from the TR on bell1 feed the 0V to bell2, then from bell2 TR back to panel.

thanks for the info. telectrix - so i will need to connect 2nd box srtaight to control panel as in tazz's diagram?

No just connect to existing bell box if required

Rudie · Feb 7, 2013

thanks, but the only thing of what to connect is the RT on bell2 as on tazz's diagram, this connects to the control panel RT.

Hopefully this will show Telectrix wiring, as its hard to put down in text, also put the optima and bell box terminals in for you

Thanks Tazz, i'll order another texecom and try this as soon as i can. will each siren box have everything working - siren/flashing led/strobe/tamper? once its up i'll do the walk through tests.

Yes on testing both will sound, forgot the strobe, but its just linked to the other strobe terminal

Hi, I have taken a photo of the control panel - will try and take a photo of existing siren box wiring this weekend...

From the picture, it looks like the wire feeding the sensor in the landing upstairs carries the wiring for the siren box too...

So we have

SCB T - Blue
SCB A - Black
Bell D - Red
Bell B - Yellow

Zone 8 PIR feed is white and green...

With no tamper.oooooooo

There are no tampers on the pirs but suppose I will find out if there Is a tamper on the siren box when I open it. What makes you think there is no tamper?

just traced the wires up, seems like the only wires going into the bellbox are red, black, yellow and blue...will open up bellbox when it stops raining...

Start again mate and re-terminate everything

Rudie · Feb 9, 2013

ok, i'll consider that after i open the box - but tazz's diagram can still be valid if the installer connected as in the diagram above.

Hi,

have managed to get up and take a picture of the wiring in the current siren box (tamper did work also). Here are the pictures...

what muppet thought he could install alarms? that wiring is atrocious. strobe is looped in with siren, bare conductors everywhere, and the panel looks like rats have been fighting in there. it's too untidy for a rat's nest.
