The Kidde Genesis LED EGCS ceiling speaker puts clear, code-compliant audio notification on commercial fire alarm systems without eating up ceiling real estate. White housing with red FIRE marking ships with the room-side wiring plate already in the box - no separate line item, no second order.

Built for the commercial fire alarm installer

Field-selectable wattage taps (1/4W, 1/2W, 1W, 2W) and 25V/70.7V operation mean one SKU covers most NAC audio circuit configurations on the job. The built-in DC blocking capacitor handles electrical supervision without adding external components to the circuit. Mounts directly to standard 4-inch square or 2-gang electrical boxes with a minimum 2-1/8" depth. UL listed (S218, S5389), ULC listed (S218), and FM Approved.

Key benefits

  • Field-selectable 25V/70.7V and 1/4W to 2W taps - one device fits the design, stock one SKU for multiple applications
  • 87 dBA max output with 0.81 STI speech intelligibility rating - clear, intelligible audio in reverberant commercial spaces
  • Room-side wiring plate included - no separate order, no waiting on a second shipment
  • Low-profile ceiling mount at 6.8" diameter and under 2" projection from the mounting surface
  • 12-18 AWG screw terminals with in/out wiring for straightforward daisy-chain runs
  • UL, ULC, FM listed and FCC Part 15 Class B compliant

System requirements

Requires a compatible fire alarm control panel (FACP) with 25V or 70.7V NAC audio output, or a separate audio amplifier/booster connected to the FACP. Mounts to a 4-inch square electrical box (minimum 2-1/8" depth) or 2-gang box. Optional EGCTW white trim plate covers exposed box edges for a clean finished look.

FAQs

What wattage taps are available and how do I select them?
The EGCSWF has four field-selectable wattage taps: 1/4W, 1/2W, 1W, and 2W. Selection is made via a switch accessible on the device. Choose the tap based on your NAC circuit's power budget and the required sound pressure level for the space.
Can I use this on both 25V and 70V audio circuits?
Yes. The speaker supports both 25V and 70.7V operation via a field-selectable switch. One SKU works on either circuit voltage, which simplifies stocking and reduces the chance of grabbing the wrong device off the truck.
What electrical box does this mount to?
Standard 4-inch square box (min. 2-1/8" depth) or 2-gang box. For surface mount, use Kidde 27193-26 (white) or 27193-21 (red). Optional EGCTW/EGCTR trim plate covers exposed box edges.
What wire size does the EGCSWF accept?
12-18 AWG on screw terminals. In/out terminals support daisy-chain wiring runs - no wire nuts or separate splice box needed at each device on the circuit.
Is this compatible with my fire alarm panel or amplifier?
Works with any FACP or audio amplifier that provides 25V or 70.7V NAC audio output. Built-in DC blocking capacitor handles supervision. Verify your panel's wattage budget supports the selected tap.
Can this be installed in a plenum ceiling space?
The speaker mounts to a box at ceiling level, not concealed above the tile. If the space above is a return air plenum, use plenum-rated wiring (FPLP) per NFPA 70. Box and penetration must meet local AHJ requirements.
Does the room-side wiring plate come included?
Yes. The EGCSWF ships with the room-side wiring plate (GRSW) in the box. Includes a diagnostics check bar for field testing. No separate order needed.
What is the STI rating and why does it matter?
STI of 0.81 at 1W (UL 2572). Measures speech clarity in reverberant spaces. Above 0.70 is "good," above 0.80 is "excellent" - critical for voice evacuation and mass notification where occupants must understand spoken instructions.
