The FX-IDCWS connects two normally-open initiating device circuits to a Kidde FX Series fire alarm control panel on a single SLC address pair - one waterflow alarm circuit and one supervisory circuit. Rotary TENS and ONES dials set the address on-site with no programming tool required, and the compact footprint fits standard 4-inch electrical boxes.

Built for the commercial fire alarm installer

Each module requires two consecutive addresses on the SLC loop and monitors both circuits independently. A waterflow switch activation reports as an alarm condition, while a supervisory switch activation reports as a supervisory condition. Class B circuit operation with 47 k EOL supervision keeps wiring straightforward. Compatible with Kidde FX Series intelligent analog addressable fire alarm control panels. UL and ULC listed.

Key features

  • Dual IDC monitoring on one module: waterflow alarm and supervisory circuits share a single device, reducing panel point count and box fill
  • Rotary address dials: set TENS and ONES on-site without a laptop or programming tool
  • Standard box mounting: fits 4-inch square boxes (1-1/2" or 2-1/2" deep) and 2-gang boxes
  • Low SLC loop load: 550 A standby, 725 A activated - leaves headroom on longer loops
  • Wide operating range: 32F to 120F at up to 93% RH, suitable for mechanical rooms and riser closets

System requirements

Requires a Kidde FX Series analog addressable fire alarm control panel and connection to an SLC loop. Each module occupies two consecutive addresses. Wire with 12-18 AWG conductors, max 50 circuit resistance. Supervised with 47 k EOL resistor (P/N: EOL-47, ordered separately).

FAQs

How many SLC addresses does this module use?
Two consecutive addresses per module. One address monitors the waterflow alarm circuit, the other monitors the supervisory circuit.
Does this work with Kidde VS Series panels?
No. The FX-IDCWS is designed for the Kidde FX Series analog addressable fire alarm control panels only. Check the VS Series module catalog for compatible alternatives.
What EOL resistor does this require?
47 kΩ (Kidde P/N: EOL-47). One resistor per IDC circuit, installed at the end of line.
Will this fit a standard 4-inch square box?
Yes. Mounts in a standard North American 4-inch square box, either 1-1/2" or 2-1/2" deep, or a 2-gang box. No special backbox or trim ring required.
What wire gauge can I use?
12, 14, 16, or 18 AWG. Maximum circuit resistance is 50 Ω (25 Ω per wire), maximum capacitance 0.1 μF.
