Texecom Alarm System + Protect 375

[Anchor1783]

In short; The 375 Smoke Protect System requires primary and secondary triggers.
Both must be external 12v to trigger the smoke generation.
 

I've taken the primary 12v from the bellbox (bell) trigger.

The secondary should be from a PIR to detect motion in the room the smoke system is installed in before activating.

I've attached manuals to both systems. Please note that OPT3-4 is not available on this system.

I need to trigger the secondary on 375 smoke protect with 12v coming from the PIRs however the pirs I have are resistance based and do not output 12v on alarm/trigger. What can I do?

Invert the 2 negative output?

 

Or 

 

Use relays from the neg outputs?

Use a relay board on the Stu outputs if it's a 48?

Add an expander with 8 outputs?

 

Whatever works for you ?

Agreed use a relay to give you a clean switch

Concerned about competence to do this with the questions your asking and also as it's the DIY section...

From what you say I assume it's a PE48. You should do auxiliary equipment like this with isolators adjacent the control panel.

So an output drives a transistorised relay for the "armed" and "primary" but go via an isolating keyswitch for testing.

You don't explain what brand sensor you are using but I would have it drive a relay with the relay output connected to the "secondary".

All of this stuff would have it's own 12v boxed supply and electrically isolated (galvanic) from the Texecom system.
