The Visonic MCT-302 transmitter has a jumper setting to enable/disable \"restore reports\".
The default setting is \"enabled\", which is how I\'ve left them. The light on the transmitter flashes when the door is opened, and flashes again when it is closed (the light indicates transmission).

I presume that means the MCR-308 receiver zone output will close again, so Comfort senses the door has been closed.
Will give it a try !

By the way, can I say your support on here is excellent and quick
One of the things that persuaded me to take the plunge with Comfort on a DIY basis !

Thanks for the compliments
There are those who  say that we should not allow or encourage self-installers as they may  make a mess of it and give the product a bad name.
I disagree because in our experience, those who decide to do the installation themselves (even though they are not a large number) are highly motivated and capable,  tend to make full use of Comfort\'s capabilities, and give us good word of mouth.  Most importantly they  read the instructions.
We have had very few problems over many years with DIY installers who are unable to install and program Comfort once they have decided to take it on

I tried this yesterday, and the transmitters DO report door closed.
I armed to Away, opened the door, Comfort reported \"Front Door\". I closed the door, and Comfort proceeded to arm successfully.

Thanks for allowing DIY\'s. That\'s me and I\'m about to start my second (does that make me an installer? ).

I put my first system in and ran it (and impressed many people with it ) for the last 9 years. It\'s time to move so its time to start again.

Given that my last install was so long ago and so much has changed I\'m hoping for some of that community support I came to love.

My first question is PIR\'s. Can anyone give me an opinion on whether 360 degree ceiling mount PIR\'s are any good / ok for Comfort (I\'m looking at the Optex FX-360 - there is an FX-360LP that has alarm memory latch, but I dont know what that means. Can someone explain?).

Also cabling. In the last build I started off using screened 8 core, but soon ran out. I switched to using Cat5 UTP which has worked out fine. Is there a rule for cabling? Is Cat 5UTP better than screened 8 core alarm cable?

Can more than one PIR share the same 8 core screened alarm cable on the return to the CPU or should each PIR have its own cable?

Thanks

For alarm wiring it is better to use alarm cable which is normally 7 x 0.2 which means 7 strands of 0.2 mm2. This is multicore cable which is more flexible and does not tend to break so easily compared to CAT5. Screened 8 core alarm cable is really not necessary for alarm wiring. You should use one cable for each PIR unless you have no choice because the spare cables can be used in case of cable degradation, as resistance tends to increase over the years so it allows you to double up the wires

For Keypads, SCS, RIO, Door stations and other data cables you should use CAT 5, preferably screened

Ceiling mount can be used for Comfort just like wall mounted. It makes no difference to Comfort, but you must assess the specific device used, its reliability and ability to filter out false signals. Dont know what is alarm memory latch sorry.

Can anyone advise if the \"LuNAR DT 360 Ceiling Mount PIR Grade 3\" is a suitable PIR?

It says that it comes with built in EOL resistors. Would this be compatible with Comfort?

Thanks

The \"triple EOL\" resistors would not be compatible with Comfort
Why not use the Grade 2 version? There is no benefit in using Grade 3 components unless the rest of your installation is Grade 3, and this requires a certified installer

I looked at this one because it used microwave as well as PIR which seemed like a good idea to cut down on false alarms. If this isnt compatible then would this be a better alternative?

This are compatible they dont have \"triple end of line resistors\"

There are other PIRs in the market with \"dual technology\" ie Microwave and Infrared detection to reduce false alarms. It has nothing to do with the Class 3 grading
