Some More Stupid Questions..

[zerozero]

I'm sure most people would just try this stuff instead of asking but I don't want to end up in the name and shame section later  so just double checking

 

1. I am planning to run a Texecom Exodus Fire alarm and an AMQD PIR off of Keypad 1 zones and they both need 12v power. Is there any reason why I can't/shouldn't simply use the +12v/0v off of the network terminals inside the keypad? .. I'm sure not, but just checking..

 

2. On the AMQD anti mask detectors, alongside the normal +12v/0V/T-EOL pair and test terminals there is a connector SET  that I don't really understand. In the book it says

 

SET: 12V/No connection: Detector is in the Standby/unset mode
0V: Detector is in the Alert/set mode

 

But surely I want it to be set / unset by the panel? is this used for some diagnostic function normally and I should usually leave it with no connection or is there something that I'm missing.

1. 12v is 12v

Don't forget Grade 3 systems require LEDs off except when in walk test .

No

leave it with no connection or is there something that I'm missing.

This is to let the detector know that the system is armed.

This could be for a few reasons, including disabling LED's.

There is an LED Control option in the programming for a reason.
