Kidde EG4AVRF Wall Horn and LED Strobes feature a sleek, low-profile design and energy-efficient technology that makes them less expensive to install and operate by reducing overhead. Its high-performance LEDs require fewer power supplies, backup power, and batteries. They are designed with energy-efficiency, and life safety in mind.

The EG4AVRF Wall Horn/Strobe uses high efficiency optics, combined with patented electronics, to deliver a highly controlled and efficiently focused light distribution pattern in exchange for lower current requirements. The strobes feature field-selectable 15, 30, 75, or 110 cd light output.

Compared with Xenon-type strobes, the EG4AVRF needs fewer power supplies and often smaller wire gauge, which lightens conduit requirements. They are also backwards compatible with legacy strobes, so there’s no need to replace all your existing devices to upgrade to new LED technology. In fact, EG4 strobes can be mixed on the same circuit and used in the same field of view as Xenon-based strobes. This makes Kidde’s wall horn/strobes ideal for new installations and retrofits alike.

Field-configurable sound output levels provide the flexibility modern life safety projects demand, while the Genesis LED control protocol keeps multiple strobes on compatible NAC circuits synchronized to well within NFPA 72 requirements.

Serviceability is another area where the Kidde EG4AVRF Wall Horn and LED Strobes shine. The universal room side wiring plate allows for pre-installation and electrical wiring as well as checking continuity with the included diagnostics check bar. The devices can then be easily snapped into place with the confidence of knowing the wiring is correct. The innovative under-cover diagnostic test points provide easy access to device circuit testing while mounted.



The EG4AVRF strobes are UL 1971-listed for indoor use as wall-mounted public-mode notification appliances for the hearing impaired. Prevailing codes require strobes to be used where ambient noise conditions exceed 105 dBA (87 dBA in Canada), where occupants use hearing protection, and in areas of public accommodation.

Synchronization is important to avoid triggering seizures in people with photosensitive epilepsy. All Kidde EG4AVRF strobes exceed UL synchronization requirements (within 10 milliseconds over a two-hour period) when used with a synchronization source.


The Kidde EG4AVRF wall horn output reaches as high as 92 dBA and features an improved audio frequency range compared with other horns. This results in excellent sound penetration through walls and a clear warning of danger. Horn only models may be configured for either coded or non-coded notification appliance circuits. They can also be set for high or low dBA output. This setting reduces horn output by about 6 dBA. Horn-only models may be ceiling-mounted or wall-mounted.


The Kidde EG4AVRF horns and strobes mount to the required GP10 room side wiring plate. The GP10 mounting plate is included with the device for convenient pre-installing and pre-wiring. It can be removed easily from the room side wiring plate by pushing up with a screwdriver. The cover can also be easily removed from the device with a screwdriver to access the light and sound output settings and a diagnostics test port for voltage testing. These devices also mount to any standard one-gang, two-gang, 3.5-inch octagon, and 4-inch square electrical box.

Field Configuration

Temporal horn and horn-strobe models are factory set to sound in a three-pulse temporal pattern. By sliding the tone selector switch, horn only models may be configured for constant horn output that can be coded at precise intervals by KIDDE control panels and control modules.

Horns and horn-strobes are factory set for high dB output. Low dB output may be selected by sliding the tone selector switch. This reduces the output by about 6 dBA.

These Kidde EG4AVRF strobes and horn-strobes may be set for 15, 30, 75, or 110 candela output. The output setting is changed by simply removing the cover and sliding the candela switch to the desired setting. The device does not have to be removed from the wall to change the output setting since it remains visible through a small window on the left-hand side of the device after the cover is closed.
