Detailed Product Description

-

The purpose of the GSM Mini is to interface to GSM network any alarm system that is capable to call the security monitoring station through wired telephone line.

-
By means of GSM transmission, the adapter improves the reliability of alarm reporting in cases when the wired alarm transmission does not work or fails (e.g. when the phone lines are tampered or the telephone service is suspended due to technical reasons).

-

Features of the unit:

• Analogue telephone line simulation to transfer Contact ID signals and voice
• Handling wired telephone line (PSTN), in case of its failure switch over to GSM line simulation
• Generating SMS message from the Contact ID codes of monitoring station reports (alarm, opening, closing)
• Automatic dial of pre-set telephone number as a result of picking up the line (emergency call function)
• Bell 103 / V.21 digital data communication
• The alarm system will be programmable through GSM data call (remote maintenance, downloading eventlist, etc.)
• GPRS transmission (to TEX server)

-

Application areas:

• Connecting security systems to monitoring station through GSM network using Contact ID format
• Security reserve (secondary signalling channel) to the already existing wired-telephone communicators
• Wired telephone adapter for flats, houses, cottages
• A simple emergency alarm for elderly, sick people by picking up the phone
• Remote diagnostic of security systems
• GPRS terminal for monitoring stations

-
