GSM 2G AUTO DIALER - ADT/VISONIC/HONEYWELL/UTC COMPATIBLE

Easy set up,12v in and either permanent pos/neg and switched output! Then just text phone numbers you want and alarm message and wait for acknowledgement from unit and it's ready to go! Works really well and really well priced. Will Work with any alarm for monitored system!

Not as versatile as expected.although it has two inputs effectively only one can be used.It will either call voice - with no message just silence, or it will send a text - fixed content.For this price I would expect something where I could programme voice message and distinguish between intruder and fire.I could arrange for it to turn on the alarm box remotely but not turn it off.Well constructed and probably weatherproof.

Simple to install, stores three numbers, comes with a sim card and easy to follow instructions, dials all three numbers when alarm is triggered.

Absolutely fantastic - This device connected into my original alarm, bringing its technology bang up to date. It texts me if the alarm siren goes off, meaning I know there is an unauthorised entry and I can make sure there is a response.The device works. The instructions are clear. And to a non-alarm technician, the product support from GSM is first rate - with instructions from a GSM installer on exactly which terminals to use and how to connect up.

Works fine after 12 months.alarm engineer fitted this to my existing hardwired alarm so that it would ring/text my mobile if alarmed triggered.no issues so far.requies a pay as you go sim to function.

Excellent item as described. Arrived on time

seems to be a good job.very helpful to get it fitted.

This item should not be getting five stars, it should be getting ten stars, clever built and well designed.
