Connect to any normally-open or normally closed output Detects changes in any Normally Open or Normally Closed contact closure Communicates contact data wirelessly with WSG30 base unit up to 300’ away Includes two AA batteries Optional power supply available The Wireless Dry Contact Sensor is used exclusively with the WSG30 system to interface with any normally open or normally closed dry contact. When the contact switches position the sensor will wirelessly communicate the change back to the WSG30 and users will receive an alarm via text message or email. It is ideal for monitoring the alarm outputs of other devices such as a UPS, industrial refrigerator or freezer, or security system. The sensor includes two AA alkaline batteries which will power the sensor for up to two years. An optional plug-in power supply is also available, in which case the batteries then become a backup if the main AC power fails. The wireless sensor can be placed up to 300’ away from the WSG30 or further if multiple sensors are used to create a mesh network.
