Introduction

The GSM alarm system adopts GSM network and Digital Signal Processing technology, and is widely used in security field. This system is mainly applied to the security of power transformer, electric transmitting line and street lamp line etc. With the advantages of good waterproofness, practicability, good quality and stability credibility etc, the GSM power alarm can be used in various environment of outdoor. With SMS data transmission and voice platform of GSM network, it is really realizes wireless alarm control and remote managements and solves the limitation of wired data transmission in telephone and wired network.

Main Function

* With 8 routes of wired input alarm.

* Monitor 3 phase loss voltage and single phase failure of the electric distribution network.

* Can connect line-cut/ movement/ vibration sensors etc., It will alarm when power transformer is damaged or moved.

* Send SMS to 6 preset mobile phone numbers automatically while alarming.

* Auto-dial 2 preset phone numbers and monitor the alarm site while alarming.

* Can program the alarm host and inquiry its status by SMS demand
