Kentec Gas Release Control Panels
Dedicated extinguishant release control — supervised actuator circuits, abort and manual release, commissioned with the suppression system it drives.
Brand overview
Gas Release Control by Kentec
A gas release panel is not a general fire alarm panel. It supervises the detection that confirms a fire, applies the double-knock logic that prevents a single device causing a discharge, runs the discharge delay and drives the actuator circuit.
Kentec's GRP range covers single and multi-area release control with the status indication, abort and manual release facilities a supervised releasing system requires. Intech supplies these as part of the suppression system they control, and commissions the whole sequence as one test.
- Double-knock release Two independent detectors must confirm before anything discharges.
- Supervised actuator circuits The release circuit is monitored, so a fault is reported not discovered.
- Abort and manual release Occupant-facing controls with clear status indication.
- Commissioned as a sequence Detection, delay, discharge and interlocks proven together.

System
How Release Control Works
01
Detect
Two independent detectors in the protected area must confirm.
02
Warn and delay
Occupants are alerted and a discharge delay runs, with manual hold available.
03
Release
The panel drives the supervised actuator circuit to discharge the agent.
04
Interlock
Dampers, air handling and door release operate as part of the same sequence.
Applications
Where Release Panels Are Specified

Models & variants
Sigma A-SI
The Sigma A-Si range of status indicators provides detailed status information for Sigma A-XT releasing control equipment. All models provide high brightness, LED indication of Manual Only, Automatic and Manual, Abort Operated, Disabled, Imminent and Released conditions. Models are also available with zonal fire indicators and a common trouble indicator. For systems where local control of the Automatic/ Manual mode and or a Manual extinguishant release control are required, units are available with these controls fitted. All models have supervised inputs for the remote connection of Automatic/Manual mode and abort switches.

Sigma A-XT Extinguishant Abort Switch
The Sigma A-XT Abort Switch connects to the Abort terminals of the Sigma A-XT releasing panel. Any number of Sigma A-Si Abort Switches may be connected to the circuit. The last switch must have the end-of-line device from the Abort circuit terminals of the Sigma A-XT releasing panel fitted across its connections to provide open and short circuit supervision. The unit is supplied mounted to a steel enclosure but may also be flush mounted to a single gang electrical box.
Sigma A-XT Ancillary PCB
The Sigma A-XT Ancillary Board is compatible with all Sigma A-XT control panels. The board provides volt-free, normally-open contacts, enabling control of sub-systems and plant remotely from the main panel over a two-wire data bus. Ancillary boards require only a two-core data cable from the main control panel and a two-core power cable from the main panel. Up to seven Ancillary boards can be connected to a control panel and each is allocated an address from one to seven using a binary coded DIL switch. A mixture of status units and Ancillary boards, up to a maximum of seven of each type, can be connected to the serial data bus. 1101, 11th floor Technocity IT Premises co-op Society, Sector X-5/3, TTC Industrial Area, Mahape Navi Mumbai 400710 All Rights Reserved By Intech Fire & Security Pvt Ltd.

Frequently Asked Questions
What project teams usually ask about Kentec GRP Gas Release Panel.
Still have a question?
Speak directly with one of our fire safety engineers.
Call +91 88795 33000Why not use the main fire alarm panel?
A release panel does things a general panel does not: double-knock confirmation, discharge delay, supervised actuator circuits, abort and manual release with status indication.
What is double-knock?
Two independent detectors must both confirm before the panel will release, so no single device can cause a discharge.
What does the abort control do?
It holds the discharge while someone is still in the room, with the status clearly indicated. It is part of making the system safe to occupy.
Does it interface with the building fire alarm?
Yes. The release sequence normally reports to the main panel and interlocks with dampers, air handling and door release.
Is it commissioned with the suppression system?
It has to be. We prove detection, delay, discharge and every interlock as one sequence rather than testing parts separately.
Does Intech supply and maintain it?
Yes — supplied as part of the suppression system it controls, commissioned together and maintained under AMC.
