SIGA-SEC2
Releasing Module
The Signature Series Releasing Module (SIGA-REL) is an analog addressable
module that works with fire suppression systems designed to release extin-
guishing gas such as Halon. Its primary function is the control of sprinkler pre-
action routines and the initiation of suppression system deluge functions. The
module is easily configured in the field and offers a wide range of options that
prevent the unnecessary release of extinguishing agent.
The SIGA-REL is a network component consisting of:
• Two supervised release circuits
• Two supervised pre-release circuits
• One supervised manual release input circuit
• One supervised abort circuit for N/O abort switch
• One first alarm output relay
(Form C Contact)
The releasing module includes a built-in timer that inhibits the deluge
function during the pre-action routine. One of four pre-action routines,
may be selected by means of dip-switches on the module. The duration of
automatic and manual time delays, as well as the abort time settings are
also selectable with dip-switches. The SIGA-REL mounts inside an MFC-A
cabinet or other suitable UL-listed electrical enclosure. Each MFC-A will
hold one SIGA-REL.
Available releasing module accessories include dedicated pull stations,
abort switches and service switches. Together with the SIGA-REL, they
comprise a complete fire suppression package.

Dual Input Security Module
The SIGA-SEC2 is an intelligent analog addressable device used to connect one or
two normally-open or normally-closed dry contact security circuits. The actual func-
tion of this module is determined by the “personality code” selected by the installer.
This code is downloaded to the module from the Signature loop controller during
system configuration. The input module gathers data from the devices connected to
it and converts them into digital signals. The module’s on-board microprocessor
analyzes the signal and
decides whether or not to
input an alarm, tamper, or
maintenance condition.
The module is housed in a
small thermo-plastic en-
closure designed for sur-
face mounting.
