Pet Pir False Alarm

[GiZZeRR]

Hi Guys,

First post and thought I would ask about a problem I had last year and I expect to return when the weather warms up (if my suspisions are correct).

Firstly I installed a Texecom Veritas R8plus early last year. We have a cat so I fitted ... Pet Pirs in all rooms (5), Fire Detectors (2), Conservatory (extreme heat) Pet Pir (1), Conservatory Break Glass Detector (1).

Everything works perfectly but for one thing. We have a patio door which I like to leave open about 6 inches to allow the cat access to the conservatory where the cat flap is located (the patio door is locked in this open position with bolts).

Occationally during hot weather when I return home I find there has been an alarm condition in the Livingroom (Pet Pir) which is set to "Guard". This is the room with the patio doors leading to the conservatory. Is it possible that the extreme heat from the conservatory is being picked up by the Pet Pir as movement as it moves into the livingroom through the 6in opening? It is the only thing I can think of and maybe I now need to replace the Standard Pet Pir with an extreme heat version.

Thanks

John

hi john

what do you mean " extreme heat version " and are you sure its the living room sensor not the consv thats activating ( believe me ive got the curcuits the wrong way round before now )

Hi John,

a bit dificult to gauge imo, without seeing the actual relationship to the doors and other factors.

having the patio door with a 6" gap could asentuate temperature difference's between the two rooms, i.e. if the conservatory is hot and hot air moves into the cooler adjacent room when the cat flap is used, it just might be the cause the problem.

you could try placing the errant pir on double knock to slow it down, lowers your security obviously, but i'd suggest better than the system being ignored by nearby nieghbours as 'just john's faulty alarm again' syndrome.

Insted of double knock why not fit a Dual Tech?

[GiZZeRR]

Thanks for the replies.

Firstly, anguscanplay it is the Dual Tech model for use in high temp areas like conservatories. It is def the livingroom (zone 2), Zone 1 is the conservatory and it is set as entry/exit.

arfur mo I didn't think about "double knock" I may give that a try first. Thanks.

whistle That was my next move I think, I have a spare Dual Tech but it ain't a Pet version so I'll need to buy another, if the double knock doesn't work.

Thanks Guys.

hi john,

if your conservatory is an exit route then double knock might not be so good an idea, especially if you don't have a contact on the door as final exit/entrypoint.

to exsplain for a detector on 'double knock' has to activate twice within a given time frame say 2 mins, or remain in alarm continuously for another time frame say 10 seconds. if there are two detectors on the system the 'knocks' are summed, so a single detection on the landing will be summed with a single detection in the conservatory, which then activates the alarm indicating the conservatory as the source.

if your detector is the sole device on this entry/exit route, you might not trigger it on entry when passing swiftly through to the living room, and then causing an activation from the living room.

simple this fitting alarms stuff innit!

there is an old technique used before pet ressistant pirs came about, often for cats/dogs we masked out the lower lens section with tape so your animals run underneath it, but a human being taller sets off the upper fields. real fun crawling on all 4's to test it , and when working for clients you checked on their 'orientation' first or donned rear view mirrors

you'd need quad lock

lol

the cat will set off both detectors (heat movement and & object movement) thats why

unless its one of the pet immune dueltechs

[GiZZeRR]

arfur mo The conservatory (Dual Tech Pet Immune Pir) is not the problem....it is the Livingroom (Pet Immune only) that is causing the alarm, and only on really hot days which is why I was thinking the heat from the conservatory was moving into the livingroom through the slightly open patio doors.

Any access to the house through the front door (small hall) or the conservatory door (both entry/exit) will start the timer count down. The only rooms downstairs are the Kitchen and Livingroom both set as "Guard". I know the cat can't be the cause of the alarm as the system is setup during the night with Conservatory, Livingroom, Small hall (front door) and Kitchen on Full Guard, leaving only the upper floor with bedrooms and bathroom "unset". If the cat were somehow setting off the livingroom Pir during the day, she would also set it off at night as she has access to the alarmed zones.

So to sum up, system includes ....

Conservatory = Dual Tech Pet Immune Pir (extreme for consevatorys or high heat areas). Entry/Exit (Day) - Guard (Night). Working 100%.

Conservatory = Break Glass Detector. Guard 24/7. Working 100%.

Livingroom = Pet Immune Pir. Guard Day & Night. Working 100% at night but sometimes Alarm condition during the day if conservatory really hot. Heat from conservatory entering livingroom?????

Front Hall = Normal Pir. Entry/Exit (Day) - Guard (Night). Working 100%.

Kitchen = Pet Immune Pir. Guard Day & Night. Working 100%

Bedroom 1 = Pet Immune Pir. Guard Day - Unset Night. Working 100%

Bedroom 2 = Pet Immune Pir. Guard Day - Unset Night. Working 100%

2 x Fire Detectors = Ground & Upper Floor. Guard 24/7. Working 100%

System has been running for just over a year and livingroom has always had this problem if the patio doors are left open a little. Not every hot day though, it is sporadic.

Think I've already decided to swap the livingroom out for a Dual Tech Pet Immune Pir though as I can't see it can be anything else.

Thanks folks.

Hi John,

ok, 1st you need to check and adjust the range on the MicroWave element properly, so carefully look at the instructions again and carefully set it so it will not reach within 2 feet of the door with a gap if you can do so but still maintain good coverage of the room.

there is a setting inside which will allow for more movement (pulse count) you could increase this but it will slow down the detector so it's a comprommise.

remmember also, micro wave can penetrate building structure's, so if you have say a rain pipe out side and watar is running down it in a storm, then you are relying on the PIR to prevent a false alarm.

another thought is, have you tried swapping over the two duel-tec's, it's just possible the livingroom one is more sensative than it should be or slightly faulty. you also need to ensure the widows are always fully closed and not left on night latches even the small windows, especially during wind or temperature extremes to prevent draughts and thermals causing an issue.
