Chapter 2: Installation
SIGA-REL Technical Reference Manual 25
Wiring the SIGA-REL
Caution: Do not connect the releasing solenoids before the system has been
programmed and tested, and the Signature loop controller and SIGA-REL have
reached their normal state. See Chapter 3 “Programming” and Chapter 4,
“Testing and troubleshooting” for details. Failure to follow these instructions can
result in unexpected release of the fire suppression agent.
Observe static-sensitive material handling practices while installing or servicing
the SIGA-REL. Electrostatic discharge may damage the equipment and activate
the release circuits.
Ensure that you are using a compatible power supply, as listed in the topic
“Compatible panels and devices” on page 6.
Wire the SIGA-REL according to Figure 13.
If your application requires supervision of the service disconnect station, install
and wire components according to Figure 13.
EST2 and EST3 systems have a relay confirmation function that you can
program to indicate activation of the prerelease and release relays at the panel.
QuickStart systems do not offer relay confirmation, so additional components are
required to indicate activation of the prerelease and release relays. See
Figure 14 for component and wiring details.
Note: When you use monitor or supervisory event messages to indicate
activation of the service disconnect station, prerelease relay, or release relay,
you must route those messages to the panel.
