Connect 2nd siren box

[Rudie]

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.

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.

 

[tazz]

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

 

[Rudie]

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?

 

[Rudie]

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]

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.

 

[Rudie]

Wasnt happy with his work either as we had just painted our house and he left hand prints everywhere. was recommended by a friend but suppose if we dont see behind the covers, we cant tell how bad they are. I will however tidy the wires when I connect 2nd box.

 

[shocking_eg]

Why has he linked the strobe with the bell output ?

Not enough spare cores in the cable ?

 

[tazz]

Oh dear run out of cores, looks like 0.5 mains cable than alarm cable. the link is a bit sad, the strobe functions will not work linked out.

 

[Rudie]

no, cant be, green and white are terminated at the top of the picture. So do I need to change this wiring for the strobe link?

 

[shocking_eg]

That strobe will work, but only when the siren is going off

 

[Rudie]

yes shocking_eg, strobe works when alarm goes off, but walk test of strobe does not...

 

[shocking_eg]

Isn't that because the installer used the same cable to feed the PIR or something ??

 

[tazz]

When you re terminate use the green for the strobe and diconnect the link, when the siren cuts off after 15 mins the strobe will continue to flash.

 

[Rudie]

Sure will do that first before I add the 2nd siren box.

 

[Rudie]

sorry shocking_eg, missed your comment, yes, the installer fed the upstairs pir using the same cable that feeds the siren box. so really, there should be 2 spare wires as the positive, negative, white and green feed the upstairs, yellow and blue feed the siren, so got a spare brown and orange.

tazz, is it the strobe -, as this feeds my auto dialler?
