The Kidde GSA-RM1 monitors the 24 VDC auxiliary riser circuit that powers Genesis Series sounder bases on the Signature data loop. When the riser loses power or faults, the module reports the trouble condition directly to the FACP - no separate monitoring circuit required.

Built for the commercial fire alarm installer

The GSA-RM1 connects to the SLC (Signaling Line Circuit) as a single addressable point, keeping loop device counts low while adding riser supervision to sounder base installations. UL and ULC listed for commercial fire alarm applications. Compatible with Kidde Signature Series fire alarm control panels and all Genesis Series sounder bases in the family.

Key features

  • Monitors 24 VDC auxiliary riser: supervises the power circuit feeding Genesis sounder bases and reports faults to the panel
  • SLC-addressable: occupies one address on the Signature data loop for centralized trouble reporting
  • Compact inline form factor: mounts near the riser connection point without taking up backbox space
  • UL and ULC listed: meets commercial fire alarm code requirements in the U.S. and Canada
  • Fire-plus-CO mode support: required component in dual-notification sounder base configurations

System requirements

Requires a Kidde Signature Series FACP with an available SLC address. Used in conjunction with Genesis Series sounder bases (GSA-AB4G, SB4U, SB4U-LF, GSA-SBT) powered by a 24 VDC auxiliary riser circuit. Wire the SLC loop with 12-18 AWG conductors per Kidde specifications.

FAQs

What does the GSA-RM1 monitor?
It monitors the 24 VDC auxiliary riser circuit that powers Genesis Series sounder bases. If the riser loses power or develops a fault, the module reports the trouble condition to the FACP over the SLC loop.
Does the GSA-RM1 require its own power supply?
No. The module draws power from the SLC (Signaling Line Circuit) data loop. It monitors the 24 VDC riser but does not draw operating power from it.
Which sounder bases work with the GSA-RM1?
All Genesis Series sounder bases: GSA-AB4G (Audible Base, 4-wire), SB4U (Universal Sounder Base), SB4U-LF (Low-Frequency Sounder Base), and GSA-SBT (Temporal Sounder Base).
Is the GSA-RM1 required for every sounder base installation?
It is required when sounder bases are powered by an auxiliary riser circuit that needs supervision per code. Fire-plus-CO dual-notification configurations specifically call for riser monitoring. Check local AHJ requirements for your jurisdiction.
How many SLC addresses does the GSA-RM1 use?
One address on the Signature SLC loop. It appears as a single monitor point on the FACP, reporting riser normal or riser trouble.
