biggaz Posted February 25, 2014 Share Posted February 25, 2014 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? Link to comment Share on other sites More sharing options...
matthew.brough Posted February 25, 2014 Share Posted February 25, 2014 Any ideas? Build a brick wall in front of the detector. That'll do it www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
Adi Posted February 25, 2014 Share Posted February 25, 2014 jumpers in the detectors, correct terminating? I really can't be ar**** with it anymore. Link to comment Share on other sites More sharing options...

AdrianMealing Posted February 25, 2014 Share Posted February 25, 2014 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. amealing@texe.com Head of Industry Affairs Visit Our Website Texecom Link to comment Share on other sites More sharing options...
SouthernBrad Posted February 27, 2014 Share Posted February 27, 2014 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? Any comments / opinions posted are my opinion only and do not represent those of my employer or Company Link to comment Share on other sites More sharing options...

matthew.brough Posted February 27, 2014 Share Posted February 27, 2014 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? www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...

matthew.brough Posted February 27, 2014 Share Posted February 27, 2014 How about the microwave method. How does that work? www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
AdrianMealing Posted February 27, 2014 Share Posted February 27, 2014 How about the microwave method. How does that work? It uses a second Doppler pulse and detects the action of masking, I.e the hand and person with the object in close proximity to the detector. Still can pass the required tests, but not the best method IMHO. Cheaper to manufacture of course has less components and firmware required. amealing@texe.com Head of Industry Affairs Visit Our Website Texecom Link to comment Share on other sites More sharing options...

jiml Posted February 28, 2014 Share Posted February 28, 2014 Pyronix use microwave. The range is adjustable from zero to about one meter. Once an object or mist from a spray gets that close we start a hunt mode. Nothing for 20 seconds (allow polish to dry) then for 40 seconds we look for movement on both parts of the DT. If detected, no fault. If one or other does not see movement, we show the fault. The fault can be cleared by activating the detector proving both parts are now not blocked. This method protects both the IR an the MW from being blocked. Link to comment Share on other sites More sharing options...
