What dialler you have?
It's a Menvier SD3.
He could isolate the output from panel to the dialer with a keyswitch and a DP relay (2nd output for a buzzer or led )
Sounds like a possibility - how would I go about this? Bearing in mind, I'm not great with relays!

I have a Guardall PX48iAssumed all on same zone, right.
What I have on a Menvier panel is all smokes on a shunt group so keying in '3333' is a shunt user which fires an output (buzzer)
but ignores the smokes.
I believe you could do this on a Texecom too, but never tried it. What make is your panel?

I thought about that but I have several smokes on different floors so would need multiple units...Fit the zone omit unit to the N/C smokes circuit, not the dialler!
If you are using EOL resistors, these need to be fitted at the omit unit - as per the instructions.
Usually this could cause a problem if only using 4 core wiring etc... as it 'converts' the EOL to DP
but as it's smokes this should all be fine.
Make sure you use the facility to connect a buzzer or similar so it can't be left in test (omitted) without realising.
Point taken about the buzzer.

Hi all,
Was hoping for some advice on an element of my system that I'm currently tweaking. I have several smokes attached to my system and a third party gsm dialler that calls out when fire/smoke is detected. The problem I have is that when I test the detectors, the dialler calls out for each test and this tends to not only annoy my key contacts (even though they are forewarned) but it costs a fair amount too!
I have been pondering a way of omitting the output in a straightforward and easy way so that the testing does not immediately cause dial out. I don't want a delay on the output firing as it would need to be substantial given the distance from the furthest smoke and the nearest keypad to it.
The output is +ve constant, going -ve on activation. I have a Menvier zone omit unit that 'seems' ideal for the situation - a simple key turn and the output doesn't fire whilst I test each detector. However, it appears the unit omits NC zones and mentions nothing of tolerating a 12v/0v outputs...
This is where I could use some advice! I have thought about relays that may help but I am not electronically minded with regard to relays so not sure.
The other solution is to go through the alarm menu each time i run a test and switch the output off - but this is time consuming and I would need to check carefully that I have put it back 'on line' after the testing...
Any thoughts?

I have been looking at a 12v relay which I could trigger from the panel, which then opens NC contacts - these could go through the Menvier zone omit unit, into another zone on panel which I could program to activate another output which is connected to the dialler! A bit long winded but I'll think it through some more...
