If you have ever wanted to connect your alarm system into a UPB network then the M1PCSPIM is what you've been looking for. UPB is like X-10 technology but more powerful and with less apt to fail. HERE
You can connect this into any M1 series panel. You wire the the four terminals on the PCSPIM to the data bus terminals on the panel. You then enroll it and you're set. This module allows you to send signals through the house wiring to operate relays in home automation devices.
-UPB Network circuitry – powered from the AC “Primary” Line.
-M1 Data Bus Device circuitry – powered (12VDC) from the M1 Data Bus (+) & (-) terminals.
NOTE: Loss of AC primary power should not result in a missing data bus device trouble.
• Current Draw from M1: ~30mA @ 12 VDC
• M1 Bus Device Address: Preset at Address #7 [Requires bus module enrollment]
• Firmware required: 1.0.42 (std. firmware) or later
