Edwards SIGA-REL Releasing Module Price in BD

Description

Product name: Edwards SIGA-REL Releasing Module Price in BD

Brand / Manufacturer: Edwards / EST (Signature Series)

Product Overview

The Edwards EST SIGA-REL is an analog addressable agent releasing module engineered for fire suppression and sprinkler control. Communicating directly with compatible Signature Series loop controllers, it provides localized control for deluge sprinklers, pre-action sprinklers, and gaseous fire extinguishing systems (e.g., $CO_2$, clean agents, or foam).

Furthermore, the SIGA-REL integrates seven onboard circuits to eliminate the requirement for a standalone releasing panel. It interfaces with conventional field devices—such as manual release stations, abort switches, and service disconnect switches—while utilizing the fire panel communication riser for initiation and supervisory monitoring.

Key Features

• Seven Onboard Control Circuits: Hosts two supervised Class B release circuits, two supervised Class B pre-release NACs, one supervised manual release input, one supervised abort input, and one Form C zone output relay.

• Integrated Suppression Timers: Contains field-configurable DIP switch timers to program delay routines for automatic release, manual release, and abort sequences.

• Four Field-Selectable Abort Modes: Offers customizable abort routines to govern system behavior when an abort switch is pressed during countdown.

• Dual Release Circuit Synchronization: Operates two Class B release circuits in unison to actuate releasing solenoids or sprinkler valves simultaneously.

• Signature Series Intelligence: Features automatic device mapping and electronic addressing stored in non-volatile memory.

Operational & Circuit Details

• Dedicated Enclosure Requirement: Must be installed in an approved enclosure dedicated to the releasing system (such as 2-WB series, 3-RCC series, 3-CAB series, or RACCR series) with a minimum $1\text{ in.}$ ($25.4\text{ mm}$) clearance around the module.

• Power Riser Requirements: Accepts a supervised $24\text{ VDC}$ ($18.4\text{ VDC}$ to $27.4\text{ VDC}$) power riser input supplying up to $4.0\text{ A}$ maximum to output circuits.

• Solenoid Protection & System Design: Releasing solenoid circuits require RELA-EOL suppression modules to buffer against voltage inductive spikes. The module must be installed and configured in strict accordance with manufacturer releasing system instructions.

• Evacuation Signal Limitation: Onboard pre-release circuits are engineered for localized warning and are not intended to generate NFPA 72 building evacuation signals.
