The Honeywell 955PS is a 3/4” diameter recessed plunger switch that uses wire leads instead of screw terminals to connect the switch to a wired zone on your alarm control panel. You will need to splice your alarm wire to the leads on the 955PS recessed plunger switch to make a good connection. If you want an easier installation, consider the Honeywell 955PST instead as it uses staggered terminals screws for making the connection to your zone wiring. While the 955PST comes in both white (955PST-WH) and brown (944PST-BR), the 955PS only comes in white (955PS-WH).
The 955PS recessed plunger switch has an actuator that gets depressed when your window or door is closed. As the 955PS is a normally closed device, the zone circuit is closed when the actuator is depressed. Once the door or window opens, and the actuator pops out, the zone circuit will open and trigger an alarm at the alarm control panel. You should only use the Honeywell 955PS on sliding doors and windows. You need to make sure that the plunger switch can be installed in such a way that the door or window hits the plunger switch straight on. If you installed the 955PS in the door frame of a standard door, the door would hit the actuator on its side and either break the switch or the door would not be able to close. You can use the Honeywell 965RPT recessed rolling plunger switch in standard doors as it has a rounded actuator.
You will need to drill a hole with a diameter of 3/4” into the frame of your sliding door or window to install your Honeywell 955PS recessed plunger switch. After drilling the hole, you should run a wire from your alarm control panel to the hole. Use the (2) conductor 18” wire leads to connect the 955PS to your zone wire. You will need to splice, solder and tape the wires together for a good connection. Finally, push the 955PS plunger switch into the hole so that the switch is flush with the window or door frame. Only the plunger switch actuator should be sticking out. Make sure that when the door or window is closed, the plunger switch is fully depressed.
The Honeywell 955PS recessed plunger switch has a rating of 100mA at 24VDC.
