Radio Fire Alarm Systems

A suppression panel control is a device used to manage fire suppression systems. It controls the release of extinguishing agents, such as gas or chemicals, during a fire. These panels are commonly installed in critical facilities like server rooms and data centers.

One example of a suppression panel control is the Sigma XT extinguishant releasing panel by Kentec Electronics Ltd. It is widely used in various premises worldwide and offers excellent value and performance for small to medium fixed firefighting installations. The Sigma XT panel features three detection zones that can be configured to activate extinguishant release based on inputs from any combination of these zones.

It is robust, easy to install, and has all the electronics mounted on a single, removable steel plate.

Another example is the suppression panel control used in server rooms. These panels typically cover two to three fire zones and include features such as a gas release button, automatic and manual key switches, and built-in battery backup. They can also be integrated with Building Management Systems (BMS) for remote monitoring and alarm notifications

Sigma XT+

The Sigma XT+ range combines Sigma CP conventional fire detection from two to eight zones.

With highly configurable extinguishing control modules, it provides an integrated control solution for extinguishing systems with up to four protected areas.

The fire detection section connects to the extinguishant control modules via a serial link which allows secure, bi-directional transfer of data between the two. Sigma XT+ modules may be mounted remotely in separate enclosures and connected to Sigma CP panels via this serial interface to provide central fire detection and control with distributed extinguishing systems.

Sigma XT+ modules may also be mounted separately from fire detection and control equipment and activated by addressable output modules or volt free contacts from other systems via two monitored activation inputs.
