Geist RDPS / RDPS-50/100 Door Position Sensor

Condition: New

Geist's door position sensor helps you keep track of whether data center doors are open or closed. You can use a web interface to check the position of the door, or an alarm can be set to provide you with an alert whenever a secure door is opened. Consisting of two main components - a magnet and a switch with terminals connecting the signal wires - the distance between the pieces widens whenever the door is opened. This is how Geist's door position sensor detects whether the door is open or closed. The sensor can be easily hooked up to I/O ports so that it can relay information about the door position.

This sensor offers a low-cost method to monitor access doors or cabinets that should remain closed. The non-contact magnetic switch mounts to the door of a server rack or equipment room and connects to a Geist Climate Monitor. Remotely check the door status through the web interface or use alarms to notify you if a door is open.

The sensor consists of two main parts, a magnet and a switch with terminals to connect the signal wires. The magnet mounts to a door or access panel, while the switch mounts to the frame. When the door is closed the two pieces should be within 1/2” of each other. When the door opens this distance increases, eventually toggling the switch. This allows the Geist Climate Monitor to know when the door is open.

Connecting to the Geist Climate Monitor

There are two options for connecting the door position sensor to the Geist Climate Monitor. You can connect the sensor directly to the Analog Input Terminals. If other sensors occupy these inputs, or the climate monitor doesn’t have them, then you can use a Analog to Digital Converter to connect the sensor to a digital port.

Multiple door position sensors can be wired in a series to a single Analog Input or Analog to Digital Converter. This is a good way to free up inputs when you don’t need to know the specifi c door that is open, just that at least one door in the group is.

Alarms

You can confi gure alarms using the Geist Climate Monitor’s web interface. With the appropriate alarm thresholds the Geist Climate Monitor will send you an alert via email or SNMP trap if a door is detected open. Some units can also trigger an alarm buzzer or energize an output relay in response to an alarm.
