I'd be cautious of those units as they don't seem to be meet 50131 They maybe OK I don't see a dt will help a movement sensor isn't intelligent enough to determine object size ie pet vs human crawling etc.

I've been continuing searching, and I've found a couple that claim to be what I need: https://www.amazon.co.uk/OWSOO-Infrared-Microwave-Detector-Pet-Immunity/dp/B086KZLBHS/ref=pd_rhf_dp_s_pop_multi_srecs_sabr_0_7/261-3684634-4703540?_encoding=UTF8&pd_rd_i=B086KZLBHS&pd_rd_r=0c400fde-1f11-4439-a0f7-1e0b458ff418&pd_rd_w=x3VtB&pd_rd_wg=cAGmP&pf_rd_p=5864a8c4-0ac6-4e57-aa01-41e26a7ef9f7&pf_rd_r=Q17WB9KHH8YJ11XB6S1T&psc=1&refRID=Q17WB9KHH8YJ11XB6S1T or perhaps https://www.amazon.co.uk/Anti-Pet-Infrared-Detector-Security-Waterproof/dp/B07MZTYVBK

Thanks, of course the system came long before there was any suggestion of pets... Do you think a dual-tech sensor might work better than just IR ? I'd not thought of putting a standard sensor in its place, - I'd no idea there were ceiling brackets for these sensors, but wouldn't the detection pattern be "off"..? Cheers

I'm not a fan of pet sensors anyway but I'm afraid I don't know of a ceiling detector. You can of course use a standard sensor with ceiling bracket. The best way in any system with pets is peremiter protection not space protection

Hi guys, I’m curently using a couple of Texecom RF 360 PIR sensors (from your good selves). I’ve had them in place for several years covering some common hall/landing areas, all good. Last year I got a cat… Even on pulse count=2 these sensors are not pet immune, and as a result I’ve had to stop arming the alarm, otherwise the cat will set off false alarms all the time. 🙁 I need to stick with 360 ceiling mounted sensors as the wiring is in place inside a finished ceiling. I have a little void, so I could potentially change from surface to recessed flush mounting if neces

Agreed I doubt both sensors are faulty

Hi I am trying the other sensor lux wire as I post this and I will let you know how it goes? usually takes 2 to 3 days before it fails. If this one fails than its highly unlikely to be the sensors as surely 2 wouldn't go bad at the same time. Also i don't know how the switch lux connection works but maybe its not registering the sensors lux input as it should? so therefore doesn't make the connection to the lights? I will let you know either way after a week or so. thanks for your help and support so far. regards Sid Dine

Also when powering off will also reset the sensors

I would suggest it's a sensor if adjusting the lux brings it back. Have you tried another lux input from another sensor?

Ok after a few weeks of testing I have come the the conclusion that its the switcher as every few days or so it stops working but turning the lux actuator towards daylight it works again. If I return it to the position that it has been working for the few days it doesn't switch on so have to turn off at the mains and then it starts working again after turning back on. Please can you send me an RMA so I can return for a replacement regards Sid Dine

I'd check the wiring between the panel and the sab. The links should be removed when wiring in. This is done to prove the panel is functioning on first power up.

I have recently changed a Optima compact Gen 4 panel as a favour for someone. The first panel that was bought through Amazon had a fault on it. A second unit has since been fitted and all is working except the new Siren which is a Reson 8. The unit comes with pre-fitted links across TA TAMP and PA. The manual states that these should be in place when powering the unit up. This contradicts some advice on online instruction that says to remove the link to T A when wiring the siren. The external siren does not sound or flash when an alarm is activated, internal sounder in board wo

Yeah sure. Im just hoping to prove if its the sensor or the switcher. Disconnecting the L wire should make it come on all the time regardless of pot position so that will prove if its a switcher or sensor issue TS

Hi only one pir was connected to the L so disconnected it and connected the other pir to the L in case the original one connected was defective, but same results. I had to alter the LUX to 3 o'clock to get it to come on at dusk when before it was set to six o'clock so I don't understand why the lux actuator has changed value. As i said since I reset it today I will have to see how it gets on in the next few days and let you know if it doesn't respond again after a day or two. Please leave this ticket open until I am happy its working properly or not as your team have sent me a RMA returns f

yes both L connections. I think it just uses z1 L for both but ill check once we have proved that.

Hi I have 2 pir's and 2 zones so do I need to disconnect both pir's? regards

all equipment bought and installed the same day in june 2020

1812 is the switcher.

If I have a switcher problem, which item is faulty 1812 or 1819 or 1804 regards

it could be the switcher then. If you disconnect the L wire on both zones and it functions then its the pir. If it doesnt then its the switcher. How old are the PIRs?

Happening on both zones, what should I expect to happen when I disconnect the L wire? I understand the light/lux variant but doesn't work in any shade of darkness when it stops working. regards

They only thing to do next is to disconnect the L. On the switcher the L is the Lux signal from the PIR. Is this happening on both zones or just 1? I have had it where the light level slightly changes nigh by night etc, It maybe you have a switcher issue but they are pretty solid as a rule

Hi Ok I have adjusted to on in daylight and it works but only after resetting. I will keep my eye on it over the next few days and see if keeps working and then adjust for dusk operation and see if that still works and let you know, cos when reset before it only worked for 1 night then off again. What I don't understand is why the lux position would have changed as nothing been altered in anyway?. regards Sid Dine

Thats great. Wnated to check you hadnt got 2 L wires connected. Id adjust the Lux pot to minimum and see if the lights work all the time (ie daylight too)

Ok here are the pictures you requested. Is there anything I can try to eliminate the PIR 1804, control box 1812 or the 1819 switch so I can try and pin down which is at fault? as I said, been working for months with no problems so can't be the settings, must be an intermittent fault as after a reset i.e. turning the power off and back on it starts to work as normal for a day or two the reverts back to not working again.
