Description

Overview

The Kidde EG4SVRN Wall Speaker/Strobe combines high performance output with a sleek low-profile design and energy-efficient technology that makes it less expensive to install and operate. The high-performance LEDs require fewer power supplies, backup power, and batteries – designed with energy-efficiency, and life safety in mind.

The EG4SVRN speakers feature selectable wattage taps, while speaker strobes allow for both wattage and light output levels to be configured in the field. Both settings remain clearly visible — even after final installation. Speakers are also capable of both 25V and 70V and voltage in a single model with a field selectable switch. All this flexibility allows devices to be easily fine-tuned to exactly how they’re needed to perform. All Kidde speakers include a DC blocking capacitor to allow electrical supervision of the audio distribution circuit.

Kidde’s EG4SVRN 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. Strobes feature field-selectable 15, 30,75, or 110 cd light output.

Compared with Xenon-type strobes, the EG4SVRN offer greatly reduced current draw which provides benefits in longer circuit lengths, more devices per circuit, smaller wire gauge and reduced power supply quantities for an installation. 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, the EG4SVRN strobes can be mixed on the same circuit and used in the same field of view as Xenon-based strobes. This makes these devices ideal for new installations and retrofits alike.

Field-configurable sound output levels provide the flexibility modern life safety projects demand, while the LED control protocol keeps multiple strobes on compatible NAC circuits synchronized to well within NFPA 72 requirements. They also meet NFPA and UL 520Hz requirements for sleeping areas making them ideal for new construction or retrofits.

The EG4SVRN speakers produce crisp, clear voice audio output that is highly intelligible over large areas. In an emergency, intelligibility is critical to life safety. Intelligibility is measured in Speech Transmission Index and anything above .76 is considered excellent. EG4S Series speakers deliver audio with an STI of .81.

Serviceability is another area where the EG4SVRN devices shine. The universal room side wiring plate allows for preinstallation and electrical wiring as well as checking continuity with the included diagnostics check bar. They 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.

Application

Strobes

Kidde’s EG4SVRN 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 EG4SVRN strobes exceed UL synchronization requirements (within 10 milliseconds over a two-hour period) when used with a synchronization source.

Speakers

The suggested sound pressure level for each signaling zone used with alert or alarm signals is a minimum of 15 dB above the average ambient sound level or 5 dB above the maximum sound level having a duration of at least 60 seconds, whichever is greater.

Kidde’s EG4SVRN high fidelity device features 87dB of sound output along with a highly intelligible Speech Transmission Index (STI) rating of .81. They are also effective in areas subject to high levels of ambient noise as well as for hotels, dormitories and other residential occupancies that have sleeping areas that require 520Hz tones.

Installation

The EG4SVRN speakers and speaker-strobes mount to the required GRSW room side wiring plate. The GRSW mounting plate is included with the device for convenient pre-installing and pre-wiring. The device 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. They also mount to any standard two-gang and 4-inch square electrical box.

Field Configuration

Kidde EG4SVRN LED speakers are capable of both 25V and 70V operation depending on the system, The voltage is set via a switch under the cover. Speakers also may be set for ¼, ½, 1, or 2 watt operation. The wattage setting is visible through a small window on the side of the device and is changed by simply sliding the switch under the cover until the desired setting appears in the window. The speaker does not have to be removed to change the wattage, only the cover skin.

Its LED clear strobes and speaker-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. The setting remains visible through a small window on the left-hand side of the device after the cover is closed.
