Hi,

 

Has anyone got any experience testing grade 3 anti mask detectors, and the anti mask feature? I've been playing with Honeywell ones and Siemens ones.

 

The Honeywell one's instructions said you should see a blinking red light. I tried putting my hand infront of them, cardboard and so on, and non of that set the right light blinking.

 

On the Siemens one, it said the green light would stay on, and the same tests didn't seem to get me a green light.

 

In both cases, non of these tests got me a mask fault back at the panel. The only way I managed to get it was by wiring the 5K of resistors onto the end of the cables.

 

Any ideas?

Build a brick wall in front of the detector. That'll do it

jumpers in the detectors, correct terminating?

DT7550C & Iwise work for me ?

what controls are you using ?

How long are you leaving the masking material in place?

 

Also IFRC Siemens use Active IR so detect the masking material in place, Honeywell use the Microwave to detect masking, thus detecting the action of masking NOT the actual material in place.

Sounds like some jumpers or dip switched in the detector may need looking at to perhaps enable the anti mask option.

Could be a wiring issue too,have you checked the mask/fault relay opens when the detectors masked?

Sorry I've not got experience with either models.

What do the TEXECOM units use?

Active IR, detects the material rather than the action

Not a masking expert. Would that mean if I tipexed the lens on your g3 pir it wouldn't show mask as it's looking for an object?

Correct it would
