The IMS Room Temperature Sensor with Display is used exclusively with the Sensaphone IMS system to measure and provide real time indoor air temperatures from 0° to 35°F. The system will go into alarm when the temperature falls outside of the programmed high or low limit. The sensor comes in an attractive white plastic enclosure that can be mounted to a single gang electrical box or directly to the wall. A LCD displays the current temperature (in degrees Celcius) on the front of the sensor. The connection from the interface to the IMS system can use an existing CAT5 network wiring infrastructure, which powers the sensor and allows it to be installed in locations away from the IMS host device.
