Manufacture: kidde
Product code: GSA-RM1

GSA-RM1 Riser Monitor Modules  ⭐
✅ is intelligent analog addressable devices that form part of Kidde’s Signature line of products  ⭐
✅The actual operation of the GSA-RM1 is determined by the “personality code” selected by the installer, which is downloaded to the module the Signature loop controller during system configuration.

Product information

- Depending on their assigned personality, Riser Monitor Modules may be used to monitor telephone risers or 70 Vac audio, 25 Vac audio, or 12 Vdc to 24 Vdc risers.

- Upon the loss of a signal, the fire alarm control panel indicates an alert status. The Riser Monitor Module requires one module address

Standard Features

• Adjustable time delay

- 0 - 75 seconds (default 15 seconds)

• Monitors audio power or telephone risers

- Reports a trouble condition when voltage on the riser drops below the trouble threshold.

• Plug in (UIO) or standard 2-gang mount

- UIO versions allow quick installation where multiple modules are required. The 2-gang mount version is ideal for remote locations that require a single module.

• Automatic device mapping

- Signature modules transmit information to the loop controller regarding their circuit locations with respect to other Signature devices on the wire loop.

• Electronic addressing

- Programmable addresses are downloaded the loop controller, a PC, or the SIGA-PRO Signature Program/Service Tool. There are no switches or dials to set.

• Intelligent device with microprocessor

- All decisions are made at the module to allow lower communication speed with substantially improved control panel response time and less sensitivity to line noise and loop wiring properties; twisted or shielded wire is not required.

• Non-volatile memory

- Permanently stores serial number, type of device, and job number. Automatically updates historic information including hours of operation, last maintenance date, number of alarms and troubles, and time and date of last event.


The GSA-RM1 mounts to a standard North American two-gang electrical box, making it ideal for locations where only one module is required. Separate I/O and data loop connections are made to each module


The GSA-RM1: mounts to North American 2-1/2 inch (64 mm) deep 2-gang boxes and 1-1/2 inch (38 mm) deep 4 inch square boxes with 2-gang covers and GSA-MP mounting plates. The terminals are suited for #12 to #18 AWG (2.5 mm2 to 0.75 mm2 ) wire size.

Typical Wiring (GSA-RM1)

Modules will accept #18 AWG (0.75mm2 ), #16 (1.0mm2 ), #14 AWG (1.50mm2 ) and #12 AWG (2.50mm2 ) wire sizes. Note: Sizes #16 AWG (1.0mm2 ) and #18 AWG (0.75mm2 ) are preferred for ease of installation. See Signature Loop Controller catalog sheet for detailed wiring requirement specifications.
