Product Details

This system incorporates 2 separate external temperature sensors; allowing you to monitor temperatures at 2 separate locations. The system can be programmed to send out alarms if temperatures get too high or too low. The working temperature range is -49°C to 129°C. The alarms can be set to have a delay for notification to the administrator. The temperature alarms can be delayed. This can be set to a maximum of 6553 seconds. It can send SMS, call or both, when the alarm is activated. If it’s set to call, it will call the first administrator, if the call is not answered, it will then call the second administrator, etc. When an administrator answers, the system will stop calling. If it’s set to send SMS, all administrators will receive a SMS. Temperature alarms can also control the relays, so they can activate buzzers, flashing lights etc. Or be used as a heating control unit.

This system also incorporates 2 digital inputs. The inputs can be used for many different external applications, for an example, door switches. The digital inputs can also send alarms, using the same principles used for the temperature sensors. A delay can also be set for the input alarms.
The inputs will send an alarm when the 2 terminals are connected, and send an “OK” message when connections are removed. This can also be reversed, so an alarm is sent when connections are broken.

2 relays are installed allowing a Max. 24 Volt 1 Amp. With a NC/NO function; relays can be activated by calling the unit, sending SMS or by alarms on temperature sensors and digital inputs.

Also installed is a Power down alarm, with battery backup. This can also be set to delay the alarm. The battery will hold the unit up and running for 6-10 Hours, The unit will also send message when battery have less than 20% left.

The system can have up to 5 administrators. All administrators will receive SMS alarms. If it’s set to call, it will call the first administrator, if the call is not answered, it will then call the second administrator, etc. When an administrator answers, the system will stop calling.

All administrators have full access to the programming of the unit. Service personnel can access the unit by using the Password and get a temporary administrator privilege for 10 Minutes.

Power supply 12 Volt DC.
