Spaceage Advanced Fire Alarm Panel for BTS Shelters

Protecting Unmanned BTS Shelters 24×7

Smoke / Fire

Optical smoke sensor detects fire inside the shelter early, triggering LED flash and distinct buzzer tone before damage occurs.

High Temperature

RTD/thermistor sensor continuously monitors shelter temperature. Alarm activates when AC failure or power cut causes dangerous heat rise.

Unauthorised Entry

Magnetic door sensor with configurable entry/exit delay and 4-digit passcode prevents and logs unauthorised access events.

Keeping the above in mind, Spaceage Security developed a comprehensive Advanced Fire Alarm Panel that integrates all monitoring and alert systems into one compact unit operating on 48V DC. Unchecked conditions can compromise costly equipment and cause service disruption — this panel ensures real-time alerts via NMS to your NOC/TOC.

Where It's Deployed

Unmanned BTS Shelters

Primary application — round-the-clock fire, temp, and intrusion monitoring in remote telecom tower sites.

Telecom Exchange Rooms

Protects expensive telecom switching and transmission equipment from fire and thermal events.

Edge Data Centre Cabinets

Compact edge sites benefit from integrated multi-alarm protection without dedicated security staff.

Power Equipment Rooms

Monitors battery rooms and rectifier rooms where overheating or electrical faults pose high risk.

Frequently Asked Questions

The panel detects three conditions: smoke inside the shelter (optical sensor), high temperature beyond user-defined threshold (RTD/thermistor), and unauthorised door opening (magnetic sensor with entry/exit delay). All three trigger an audible buzzer and NMS NO/NC relay output simultaneously.

The panel operates on −48V DC telecom supply, with an accepted input range of −40V to −60V DC. This makes it directly compatible with standard BTS shelter power rails without any converter.

Yes. The panel provides potential-free NO/NC contact outputs for fire, temperature, and intrusion alarms. These dry contacts can be connected directly to any NMS or BTS alarm monitoring system for remote alerting at the NOC/TOC.
