Battery powered and external power source
The CM2000 CM-Guard is a GSM alarm module for monitoring sensors and signals . In an alarm situation, the CM-Guard will inform contacts persons using SMS and/or call. The alarm detector works on batteries, making it possible to use it anywhere. External detectors can be connected to the two inputs connectors for use with any sensor or output signal with a make or break contact. With a simple SMS message you can configure whether a connector is "Normally Open" (NO) or "Normally Closed" (NC). In an alarm situation, a message is sent via the GSM module. Five GSM numbers can be programmed. If one recipient "confirms" the call using a key, the unit will no longer call the other numbers.
