The Kidde Genesis LED EGCS Series ceiling mount speaker drops into standard electrical boxes and delivers clear, high-intelligibility audio notification for commercial fire alarm systems. With a 0.81 STI rating - well above the 0.76 threshold - voice evacuation messages come through sharp enough to act on, no guessing whether that was the alarm on a busy floor.

Built for the commercial fire installer

Selectable 25VRMS and 70VRMS taps let you match the existing NAC circuit without swapping devices. Four wattage settings (1/4W, 1/2W, 1W, 2W) give you precise SPL control across zones. The 520Hz low-frequency capability covers sleeping area requirements where standard horns won't pass inspection. UL 1480 and CAN/ULC-S541 listed.

Key features

  • Low profile design: protrudes just 1.82" from the ceiling for a clean, unobtrusive install
  • Room side wiring plate included: wire connections accessible from below without removing the device from the box
  • Selectable 25/70VRMS taps with four wattage settings for flexible zone coverage
  • 0.81 STI speech intelligibility: exceeds the 0.76 threshold for clear voice evacuation
  • 520Hz low frequency capable for sleeping area notification requirements
  • DC blocking capacitor included: prevents false activation from filtered DC supervision voltage

Mounting

Fits 2-gang boxes and 4-inch square boxes (minimum 1.5" deep). Uses 12 to 18 AWG field wiring. Red housing, unmarked faceplate - pair with optional EGCTR red or EGCTW white trim plate for a finished look.

FAQs

Does this speaker work on both 25V and 70V systems?
Yes. The Genesis EGCS speaker has selectable 25VRMS and 70VRMS taps, so it works on either system without swapping the device. Tap selection is made at the device during installation.
What electrical boxes does this mount to?
The EGCS ceiling speaker fits 2-gang boxes and 4-inch square boxes with a minimum depth of 1.5 inches. No special mounting hardware required.
Does this meet sleeping area notification requirements?
Yes. The EGCS speaker is 520Hz low frequency capable, meeting code requirements for sleeping area notification where standard higher-frequency devices don't qualify.
What is the speech intelligibility rating?
The STI (Speech Transmission Index) is 0.81, which exceeds the 0.76 threshold required for intelligible voice evacuation messages.
Can I wire from the room side without removing the speaker?
Yes. The included GRSW room side wiring plate gives you access to wire connections from below the ceiling without pulling the device off the box.
What is the DC blocking capacitor for?
The included DC blocking capacitor prevents false activation from filtered DC supervision voltage on the NAC circuit. It installs inline and ships with the speaker.
