SMS Alert Gateway

SMART SMS ALERT SYSTEM supports 4G networks

The current trend is Alarm Notification message is sent via Standalone SMS Alert Gateway.

The Alarm Notification system is moving toward incorporating the use of wireless 4G network.

This solution allows the engineers to be more mobile at work and well keep inform of the fault Alarms. The set-up is simple and cost effective. When Alarm is detected, it activates the digital/analogue input of the remote SMS Alert Gateway. The microcontroller in the Gateway will then send the Pre-defined SMS Alert message to notify the persons/engineers in-charge 24/7, anywhere. Interestingly the new model comes with 3~4 hours built-in backup battery to keep the Gateway running when there is AC source power failure.
