Thank you all for your advice.

I have decided I am going to up date and thanks to datadiffusion suggestions I am considering a Texecom Premier Elite in polymer caa-0026

It allows 2 areas and that could work for me.

First I would like to study the installation manual so as to familiarise myself with the wiring etc req. how and where can I obtain one please.

Secondly where would I find the best supplier please.

google....

 

are planning to run your 2 keypads, zone expanders, external sounder(s) & internal speaker all off the endstation ?

Yes however I now plan to use only one kp adjacent to endstation, only two expanders one at a cable distance around 10 meters and the other at around 15 meters.

Expander one will have two contacts and a dt on it, expander two will have two contacts.

The endstation and kp will have six movement detectors plus three contacts plus pa button.

How many speaker or external Sounders are you using?

One internal speaker

One external sounder

Panel and two expanders will most likely be over for two expanders. Would be thinking PSU200XP.

 

I was not expecting that.

Is the ps small on the endstation

its also standby time. You can calculate the approx demand plus switched mode power supplies dont deliver over their rating and the texecom ones have issues anyway

What ps would be best and how should I wire it into the system please

It's not the power supply current it's mainly the standby time.

You would normally calculate current for alarm and quiescent condition for all of the kit and measure it as part of the design.

i gave you the exact model number above.

The SMPS is standard on all the metal cab Premier kit.
