Overview

What it is and who it is for

The Kidde GSA-WTM is a two-circuit intelligent module for sprinkler monitoring on Kidde VS and VM series fire alarm systems with the Signature loop controller. Circuit 1 accepts Class B normally open waterflow alarm switches, and Circuit 2 accepts Class B normally open dry contact supervisory and tamper switches.

The waterflow circuit sends an alarm after its contact has been closed for about 16 seconds, and conditions on both circuits latch at the module. It runs on 15.2 to 19.95 VDC from the loop and draws 396 µA standby and 680 µA activated. Each input circuit allows 25 ohm per wire, 50 ohm per circuit and 0.1 µF, and terminals take 18 to 12 AWG wire with up to 4,000 ft to the end of line resistor.

It mounts in a 2-1/2 in deep one-gang box or a 1-1/2 in deep 4 in square box with a one-gang cover and a GSA-MP mounting plate. Red 27193-11 and white 27193-16 one-gang surface boxes and the MFC-A cabinet are available.

  • Best for: monitoring a sprinkler waterflow switch and a valve tamper switch with one addressable module.
  • System fit: Kidde VS and VM series intelligent fire alarm systems (Signature loop controller).
  • Important to know: both inputs are Class B normally open dry contacts and the module does not support 2-wire smoke detectors; installation and programming must be done by a qualified fire alarm technician per local code.

Why teams choose it

Built for fire alarm systems

  • Two inputs in one

    one waterflow alarm circuit and one supervisory or tamper circuit.

  • Built-in waterflow delay

    alarm is sent after the contact stays closed about 16 seconds.

  • Latched conditions

    alarm and supervisory states latch at the module.

  • Long input runs

    up to 4,000 ft to the end of line resistor on 12 to 18 AWG wire.
