Door Position Switches
Door position switches or dps are used to detect the open or closed status of a door relative to its frame and then relay this status to a control panel.
Door position switches. Automatic door switches hardwire these switches to automatic door openers electromagnetic locks and electric strikes and your door will open at the touch of a button or the wave of your hand. Sensing systems that count record and analyze pedestrian traffic flows to maximize the efficiency of a building s setup and ensure that inventory placement is maximized. Of force until the switch receives a signal from a time delay relay motion sensor or position sensor not included that the machine s motion. If door is held open beyond rearm time or if door is forced open alarm will sound in the chexit device.
Creates an alarm when the static conditions of the protected area change microwave detectors passive infrared detectors ultrasonic detectors beam detectors dual technology detectors. Both components require drilling a 3 4 19mm diameter hole in the door and frame directly opposite one another. A door position switch is a switch and magnet mounted on the door and frame that monitors the door status. Door position switches magnetic door position switch.
The dps w style is a normally closed switch spst. Mount these switches inside your enclosure to prevent it from opening when power is on actuating the switch disconnects power and releases the door. Usually a magnet that detects when one part of the device is moved away from the other door position switch. The distance depends on the door type and gap between the door and frame but is in the 1 2 3 4 12 18mm range.
Mount the switch to the door frame and mount the key to the door so that the key is inserted into the switch when the door is closed.
