Brand: EST FireAlarm.com Part #: 36877 Categories: , , Manufacturer Part #: SIGA-REL Tag:


The SIGA-REL is an analog addressable module that communicates directly with the fire alarm panel Signature loop controller. The SIGA-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 SIGA-REL interfaces with a number of conventional devices. These provide manual actuation of abort, release, and service disconnect functions. Together with the SIGA-REL, they comprise a complete fire suppression package. There is no need for a separate releasing panel because the SIGA-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 SIGA-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 SIGA-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.
