Summary
This chapter provides information for system designers. The SIGA-REL supports
a variety of fire suppression applications. These applications include sprinkler
systems and automatic fire extinguishing systems. The SIGA-REL works with
manual and automatic inputs. This chapter explains how the SIGA-REL fits into a
fire alarm system and how it behaves during fire alarms.

Introducing the SIGA-REL
Description
The SIGA-REL Releasing Module (Figure 1) is a Signature Series component
consisting of:
•Two supervised release circuits
•Two supervised prerelease circuits
•One supervised manual release input circuit
•One zone relay output (Form C contact)
•One supervised abort circuit for a normally-open abort switch
Figure 1: SIGA-REL Releasing Module
The SIGA-REL controls operations for deluge, preaction, and automatic fire
extinguishing systems. The release circuits control the release of gas and other
fire suppression agents by controlling the release solenoids. The release circuits
operate in unison and cannot be controlled separately.
Prerelease circuit 1 supports audible notification appliances that sound alert,
prerelease, and release signals. Prerelease circuit 2 supports visual notification
appliances.

Features
The SIGA-REL includes an intelligent microprocessor that supports:
•Deluge sprinkler operation
•Preaction sprinkler operation
•Automatic fire extinguishing operation
•Selectable abort modes
Fire suppression systems
Sprinkler systems
The SIGA-REL works with two types of sprinkler systems: deluge and preaction.
The primary difference between these systems is the type of sprinkler head (or
nozzle) that terminates the pipes. Table 1 outlines the Factory Mutual Research
Corporation (FM) requirements for deluge and preaction systems. FM also
requires FM Approved compatible release valves. See Table 4 in the topic
“Compatible panels and devices.”

Deluge sprinkler systems
In deluge sprinkler systems, open-valve sprinkler heads terminate pipes
connected to a water supply controlled by a single valve. When the system
detects a fire, it automatically opens the valve to allow the water to flow through
all of the sprinkler heads. Deluge sprinklers are useful for applications that
require the simultaneous discharge of water through every sprinkler.
The following fire detection systems meet FRMC requirements for deluge
systems:
•Wet pilot sprinkler line
•Dry pilot sprinkler line
•Hydraulic rate-of-rise
•Pneumatic rate-of-rise
•Electric

Chapter 1: Product design
SIGA-REL Technical Reference Manual 5
Preaction sprinkler systems
In preaction sprinkler systems, closed-valve sprinkler heads terminate pipes
connected directly to a water supply. The water supply is usually in the same
area as the sprinklers, and the pipes are supervised for air pressure. Preaction
sprinklers are useful where it is important to prevent the accidental discharge of
water.
The following fire detection systems meet FRMC requirements for preaction
systems:
•Hydraulic rate-of-rise
•Pneumatic rate-of-rise
•Electric
Automatic fire extinguishing systems
Automatic fire extinguishing systems automatically detect and extinguish fires.
They require no manual input because detectors automatically activate releasing
solenoids or sprinkler valves.
Improper application of fire suppression agents can lead to property damage,
injury, or loss of life. Consult the applicable NFPA documents and the AHJ for
more information.
Table 2 provides a list of the fire suppression agents and the applicable NFPA
documents.

Compatible panels and devices
Panels
The SIGA-REL is compatible with EST2, EST3, and QuickStart fire alarm control
panels.
SIGA-RELThe SIGA-REL must be installed in an enclosure dedicated to the
releasing system. No other devices may be installed in the enclosure. You can
install the SIGA-REL in any of the following enclosures:
•2-WB series
•3-RCC series
•3-CAB series
•MFC-A
•RACCR series
Maintain a 1-inch (25.4 mm) minimum clearance all around the SIGA-REL. The
clearance space must also comply with NFPA 70, the National Electrical Code.
Software
You will need the latest version of the system definition utility or configuration
utility for your EST2, EST3, or QuickStart system. These are available from our
website:
•For EST2: 2-SDU
•For EST3: 3-SDU
•For QuickStart: QS-CU

Chapter 1: Product design
SIGA-REL Technical Reference Manual 7
Power supplies
The SIGA-REL is compatible with the following power supplies:
•2-PPS, 2-PPS/220
•2-PPS/6A, 2-PPS/6A-220
•3-BPS/M, 3BPS/M-230
•3-PPS/M, 3-PPS/M-230
•BPS6A*, BPS6A/230*
•BPS10A*, BPS10A/230*
* Not compatible with FM sprinkler applications that require 90 hours of standby.
Note: The SIGA-REL is not compatible with the QuickStart power supply
(PS6 Power Supply Card).
Notification appliances
The SIGA-REL prerelease circuits support audible and visible notification
appliances. You must use appliances that are compatible with the fire alarm
control panel. Refer to the control panel documentation for a list of compatible
appliances.
Note that the SIGA-REL is not designed to generate an NFPA 72 standard alarm
evacuation signal, and does not meet UL 864 requirements for an audible alarm
notification circuit intended for evacuation.
Solenoid control relays
To activate the releasing solenoids, you must use RELA-EOL relays as solenoid
control relays. These relays buffer the SIGA-REL from valve solenoid spikes. For
more information, see the RELA-EOL installation sheet.
Manual release stations
For manual release stations, the SIGA-REL requires normally-open, dry contact
signal initiating devices. The manual release station controls only the SIGA-REL
to which it is connected.
Manual release stations must be listed with the appropriate agencies in your
area. See the heading “Listing agencies” on page 10.

Chapter 1 Product design
8 SIGA-REL Technical Reference Manual
The following manual release stations are approved by FM for use with the
SIGA-REL:
•276A-REL - Manual Release Station
•278A-REL - Double Action Manual Release Station
When using NFPA 12A and NFPA 2001 suppression agents, a separate,
mechanical manual release is required in addition to the release station
connected to the SIGA-REL.
Abort stations
The SIGA-REL requires normally-open, momentary-action abort stations. The
abort station controls only the SIGA-REL to which it is connected.
Abort stations must be listed with the appropriate agencies in your area. See the
heading “Listing agencies” on page 10.
The RELA-ABT - Manual Abort Station is approved by FM for use with the
SIGA-REL.
Service disconnect stations
The SIGA-REL requires listed service disconnect stations that are normally
closed (minimum 2.0 Amps).
Service disconnect stations must be listed with the appropriate agencies in your
area. See the heading “Listing agencies” on page 10.
The RELA-SRV-1 - Service Disconnect Switch is approved by FM for use with
the SIGA-REL.

Table 9: Compliance requirements
Item
Requirement
Power riser
When two or more SIGA-REL modules are powered from a
single riser, those SIGA-REL modules must be in the same
notification zone.
NAC synchronization
UL 864 requires synchronization of notification appliances when
they are in the same notification zone. This means that when
more than one SIGA-REL is installed, the audible and visible
notification appliances controlled by each SIGA-REL must
operate in separate notification zones. The notification
appliance output from two SIGA-REL modules cannot be
audible or visible within the same notification zone.
Evacuation tone
The SIGA-REL is not designed to generate an NFPA 72
standard alarm evacuation signal, and does not meet UL 864
requirements for audible alarm notification circuits intended for
evacuation. Notification zones must include additional NACs
and appliances capable of producing the required evacuation
tone to meet these requirements.
Horns
Horn signaling patterns are controlled by the SIGA-REL, so
configurable horns must be set for steady output.
Manual release station
The manual release station controls only the SIGA-REL to
which it is connected.
When using NFPA 12A and NFPA 2001 suppression agents, a
separate, mechanical manual release is required in addition to
the release station connected to the SIGA-REL.
Abort station
The abort station controls only the SIGA-REL to which it is
connected. However, activation of the abort switch must be
annunciated at all panels in a network.
UL 864 allows only one abort station per suppression area. This
means you cannot install more than one SIGA-REL per
suppression area.
Zone relay output
Zone relay output contacts cannot be used for a notification
appliance circuit or a nonaddressable signaling line circuit.
Service disconnect station
Activation of the service disconnect must be annunciated as a
supervisory event at all panels in a network.
