by The Leading Enterprise Internet of Things Solution Wireless Dry Contact Sensors General Description Features of Monnit ALTA Sensors ALTA wireless dry contact sensors can be used to Wireless range of 1,200+ feet through 12+ walls * detect contact between two wired contact points, an Frequency-Hopping Spread Spectrum (FHSS) external mechanical switch or a contact plate. Improved interference immunity Improved power management for longer battery life ** 1 ft (12 inch) lead wires (12+ years on AA batteries) Can integrate with switches Encrypt-RF Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages) Datalogs 2000 to 4000 readings if gateway connection is lost (non-volatile flash, persists through the power Principle of Operation cycle): - 10-minute heartbeats = ~ 22 days The ALTA wireless dry contact sensor detects when - 2-hour heartbeats = ~ 266 days there is contact between the two wired end points. Over-the-air updates (future proof) It can easily be integrated into existing switches or Free iMonnit basic online wireless sensor monitoring contact plates. When the sensor detects contact and notification system to configure sensors, view between the two end points, it will immediately turn data and set alerts via SMS text and email on the RF radio and transmit the data to the wireless gateway and iMonnit Online Sensor Monitoring and Notification System, allowing the user to immediately Actual range may vary depending on environment. * receive an SMS text or email alert. The sensor can ** Battery life is determined by sensor reporting be configured to detect both closed and open loops frequency and other variables. Other power options alerting if contact is made or broken. are also available.
