I'm currently looking for a solution for what initially seemed like a rather simple problem. Basically, what I’m trying to do is find some type of PIR/Motion detector that will work with an I/O device while not overcomplicating the install with a full alarm panel or any other unnecessary hardware, etc. These PIR devices will be used indoors within an office type environment where pretty much any motion detected, after hours, would constitute an alarm event.
I’ve had great luck recently using Optex Beams outdoors along with an Inovonics receiver in order to capture/transmit alarm events. This signal is then sent to an Axis P8221 I/O device which sends the alarm event via SMTP to a queue based alarm software. Given the success with those products, I began to first look at Optex PIR devices; namely the CX-702 given that, from what I gather, I need a device with a “Form C” relay to make this work? I believe that Honeywell has whole host of devices that are capable of this as well.
One option I considered was using a CX-702Ri along with the Inovonics receiver and Axis P8221 I/O. That option is somewhat expensive though given the added cost of the receiver and the requirement of more expensive PIR devices. Aside from that, I also don’t like using wireless/battery powered devices unless there really is no other way around it.
My second option is to put together a wired solution, but which features are required within a wired PIR detector to work with the P8221, or any other capable I/O device? In addition to that, what’s the best way to get power to those PIR devices? I’ve researched and really don’t understand how that works, even when connected to a traditional alarm panel. Is there some sort of power distribution board/box that would power a given number of these devices independent of an all out alarm panel? Aside from power, I’m assuming that the “Normally Closed” alarm wire would end up going to the I/O device itself. I’ve read the following two IPVM articles - PIR Detector Selection Guide and Inputs/Outputs Tutorial, which were a great help, but I still have some confusion on the actual install portion of the puzzle:
Any help would greatly be appreciated!
Thanks in advance :-)
