Releasing Module

Overview

The GSA-REL is an analog addressable module that communicates directly with the fire alarm panel Signature loop controller. The GSA-REL controls sprinkler, pre-action and deluge systems, and may also be used to release extinguishing agents such as CO2 , Halon, or foam. The module is easily configured in the field and offers a wide range of options that ensure dependable service, while preventing the unnecessary release of extinguishing agent. 

In addition to being an intelligent network component, the GSA-REL interfaces with a number of conventional devices. These provide manual actuation of abort, release, and service disconnect functions. Together with the GSA-REL, they comprise a complete fire suppression package. There is no need for a separate releasing panel because the GSA-REL takes full advantage of the existing control panel communications infrastructure. This ensures low-cost installations with all the benefits of Signature Series analog initiation and control. 

• Seven on-board circuits provide added flexibility. Each GSA-REL hosts:
• Two supervised Class B release circuits 
• Two supervised Class B pre-release NACs 
• One supervised Class B manual release input circuit (latching) 
• One supervised Class B abort circuit for normally-open abort switch (non-latching) 
• One first alarm output relay (Form C contact) 

The GSA-REL also includes a series of built-in timers that determine the duration of abort routines and release sequences. These timers are easily configured in the field and provide a highly flexible range of options.

STANDARD FEATURES

Ideal for sprinkler, pre-action and deluge systems
Suitable for a wide range of sprinkler applications and extinguishing agents such as CO2 and Halon.

Built-in timers
Selectable durations for abort, manual, and automatic delays.

Four abort modes
Field-configurable abort routines determine how the timers operate when the abort function is initiated.

Supervised circuitry you can rely on
Two Class B release circuits and two pre-release circuits provided.

Manual operation keeps ultimate control in plain view
The GSA-REL features a manual release input circuit as well as a manual abort input circuit.

Fully automated response leaves nothing to chance
This module’s Form C relay is ideal for room preparation routines.

Automatic device mapping simplifies installation
Signature modules transmit directly to the loop controller their circuit locations with respect to other Signature devices on the wire loop.
