The AlarmWatch unit is part of the GSM based Watch series. The AW02 combines 2 contact inputs with a single thermistor temperature input.
All products in the Watch range are truly stand-alone and are suitable for use in the most remote locations. The only limitation to use is the availability of a GSM signal. The AlarmWatch units are battery powered which is user replaceable, with a life expectancy of around two years (depending on usage). The unit can be powered by 9v if required.
Many GSM alarm units use off the shelf GSM modems. These GSM modems have a habit of losing communication usually due to problems with the network, this may only happen once or twice a year and normally all that is required is a simple manual re-set of the modem module. However not that easy if it is 200 miles away, the costs associated with someone traveling to site are high.
Watch series products use our own proven GSM communication modules. The GSM module has an onboard micro controller acting as a watchdog for the modem. Should any problem with network connectivity be detected the modem will be automatically re-set and re-connected to the network.
The system stores up to 8 telephone numbers for sending SMS messages to. Once an alarm has been registered the alarm message is sent to the first programmed number. If there is no response the other numbers are called in order until a response is received. The delay time for a response is user programmable. The Alarm message contains alarm number, alarm information and site name.
All set-up is done via the USB interface using the simple setup program, which is supplied free. A heartbeat message can be programmed at user-defined intervals, low battery text message is sent on low battery. SIM card required.
