Honeywell 956-2WH

The Honeywell 956-2WH is a recessed rolling plunger switch with wire leads attached. The 956-2WH is a unique recessed rolling plunger switch because it has (3) different wire leads and can be used as a normally open or normally closed device. Most recessed rolling plunger switches, such as the Honeywell 956RPT and Honeywell 956WH-B, are normally closed devices. When the plunger switch is depressed on a normally closed device, the switch is in a closed state. If the security system is armed while the normally closed plunger switch pops out, the switch opens and an alarm is activated. Most alarm control panels use normally closed devices but some applications require a normally open device. The 956-2WH is so versatile it can be setup as either type, normally open or normally closed.

To install your 956-2WH, you will need to run a (2) conductor alarm wire from an open zone on your alarm control panel to the door or window to be protected. You will then need to drill a hole in the door or window frame that is 3/4” in diameter. Feed the alarm wire through the hole and connect the (2) conductors to (2) of the wire leads coming out of the backside of the 956-2WH plunger switch. There are (3) wire leads so you will want to use the common lead and the normally open or normally closed lead, depending on how you’d like to use the 956-2WH. You will not have to connect anything to the unused wire lead. Finally, push the recessed rolling plunger switch into the drilled hole until it is flush with the door or window frame. Only the rollerball should be sticking out from the frame.

The Honeywell recessed rolling plunger switch has a rounded rollerball so that when you close your door, the edge of the door slides over the rounded ball and pushes it down. When the plunger switch is depressed, and the door is closed, the alarm system is happy. If the door is opened, the plunger switch pops out and causes an alarm is the system is armed or causes a fault if the system is disarmed. You will need to close all doors and windows that have 956-2WH recessed plunger switches installed before you can arm your security system.
