Analog addressable releasing module GSA-REL
The GSA-REL is an analog addressable module the communicates directly wth 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, foam. The module is aesily configrued in the field and offers a wide range of options the ensure dependable service, while preventing the unnecessary release of extinguishing agent.
In addition to being an intelligent network component, hte GSA-REL interfaces with a number of conventional devices. These provide manual action of abort, release, and service disconnect functions. Together with the GSA-REL, they compise a complete fire suppression package. There is no need for a separate releasing panel because the GSA-REL takes full advantage of the exting control panel communications infrastrure. Thí ensures low-cost installations with all the benfits of signature series analog iniiation and control.
Seven on-board circuits provide added fiexibility. Each GSA-REL host.
Two supervised class B release circuits
Two supervised class B pre-release NACs
One supervised class B manual release input circuits (latching)
One supervised class B abort circuit for nomally-open abort switch (non-latching)
One first alarm output reley (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 fiexible range of options.
Standard Features
• Ideal for sprinkler, pre-action and deluge systems : Suitable a wide range of sprinkler applications and extinguishing agents such as CO2 and Halon.
• Built-in timers: Selectable durations for abort, manual, and automatic, delay.
• Four abort modes : Field configurable which defines how the timers operate when the abort function is initiated.
• Supervised circuit you can rely on: Two Class B release circuits and two pre-release circuits pro-vided.
• Manual operation keeps ultimate control in 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 the installation Signature modules transmit directly to the loop controllers their circuit locations with respeect signature devices on the wire loop.
Application
The GSA-REL Release Module is a network component that provides control for fire suppression routines. It fulfils much the same purpose as a standalone releasing panel, but supports Signature Series Detectors as an integral part of the suppression system. GSA-REL is easy to set up and accepts programing via the control panel's SDU Rule Editor.
Accessories

+ Abort station ( RELA-ABT)
The abort station is a normally-open, non-latching device. It is used to prevent the release of agent the protected area after the release sequence has begun.

+ Service disconnect station RELA-SRV-1
The service disconnet switch is used temporarily disable the fire suppression system. One switch is installed on each of the two release circuits between the GSA-REL and the RELA-EOL end-of-line reley. Opening the service disconect switch allows the fire alarm system to be tested without activating the fire suppression system. The operation of this switch causes a trouble signal at the control panel.

+ Manual releasing station (single-action)

The manual release station is a normoally-open, dry contact signal initiating device. The 276A-REL is single-action station that requires the user to pull the release handle to initiate the release of a fire suppression agent. The 278A-REL (shown) is a double-action station that requires the user to raise the upper door, then pull the release handle to initiate the release.

+ Polarized end-of-line relay RELA-EO
The End-of-Line Relay facilitates the connection of a non-polarized releasing solenoid to a supervised, polarized releasing circuit. One relay is required per ealease solenoid.
