2 Zone GSM Auto Dialler Alarm Communicator for Burglar Fire CCTV and Access Control

The ESIM022 is a 2-zone GSM communicator designed to send alarm alerts over the mobile network when connected to a compatible alarm, CCTV, or access control system. As fewer homes and businesses maintain a traditional fixed telephone line, GSM communicators have become an increasingly important part of a complete alarm installation.

With two monitored zones, this unit can receive trigger inputs from up to two separate alarm conditions or device outputs, making it suitable for smaller installations or as a supplementary communication device alongside an existing alarm panel. When a trigger is received, it automatically dials predefined numbers and delivers a voice or SMS alert to the designated recipients.

Its broad compatibility across burglar alarm, fire alarm, CCTV, and access control outputs makes it a versatile communicator for mixed-system sites where a single device needs to handle notifications from more than one type of security equipment.

For small business premises, residential properties, and remote sites across London and the UK where a reliable, SIM-based communication channel is more practical than a landline, the ESIM022 provides a straightforward and effective alerting solution without requiring a complex panel integration.
