Field Configurable Ceiling Speaker

Genesis Series

Overview

Genesis life safety ceiling speakers are small, compact, and attractive audible emergency signaling devices. Protruding no more than one inch from the ceiling, Genesis speakers blend with any decor.

Genesis notification appliances feature textured housings in architecturally neutral white or eye-catching fire alarm red.

Genesis ceiling speakers feature ¼ W to 2 W operation, which is selectable with a conveniently-located switch. The wattage tap setting remains clearly visible even after final installation, yet it is locked in place to prevent movement after installation.

All Genesis ceiling speakers include a DC blocking capacitor to allow electrical supervision of the audio distribution circuit. Models for 25 VRMS and 70 VRMS audio circuits are available. The speaker with its sealed back construction is extra durable, is impervious to moisture and provides improved audibility.

Application

Standards generally require that notification systems produce signals a minimum of 15 dBA above the ambient sound pressure level, or 5 dBA above the maximum sound pressure level having a duration of 60 seconds, whichever is greater. This is measured 5 feet (1.5 m) above the floor.

Doubling the distance from the signal to the ear will theoretically cause a 6 dB reduction in the received sound pressure level. The actual effect depends on the acoustic properties of materials in the space. Doubling the power output of a device (e.g.: a speaker from 1 W to 2 W) will increase the sound pressure level by 3 dBA. A 3 dBA difference represents a barely noticeable change in volume.

Application Notes - Canada

(Based in part on 1995 Canada National Building Code)

The signal sound pressure level shall not exceed 110 dBA in any normally occupied area. The sound pressure level from an audible signal in a floor area used for occupancies other than residential occupancies shall not be less than 10 dBA above ambient levels, and never less than 65 dBA. In sleeping rooms the sound pressure level from an audible signal shall not be less than 75 dBA when any intervening doors between the device and the sleeping room are closed.

Typical Sound Output (dBA)

Measured at 2 watts setting in anechoic chamber

Dimensions

Installation and Mounting

All models are intended for indoor ceiling or wall applications only. Speakers are flush mounted to a North-American 4" square electrical box, 21/8" (54 mm) deep or a European 100 mm square box.

Genesis ceiling speakers simply unlatch and twist to open. This gains access to mounting screws. The shallow depth of Genesis devices leaves ample room behind the signal for extra wiring. Once installed with the cover in place, no mounting screws are visible.

Edwards recommends that these speakers always be installed in accordance with the latest recognized edition of national and local codes.

Field Configuration

Genesis ceiling speakers may be set for $\backslash frac\{1\}\{4\}$ , $\backslash frac\{1\}\{2\}$ , 1, or 2 watt operation. Wattage may be changed by simply opening the device and sliding the switch to the desired setting. The speaker does not have to be removed to change the output setting. The setting remains visible through a small window on the front of the device after the cover is closed.

Wiring

Field wiring terminals accommodate #18 to #12 AWG (0.75 $\backslash ,\backslash mathrm\{mm^2\}$ to 2.5 $\backslash ,\backslash mathrm\{mm^2\}$ ) wiring.

Sound Level Output

	25V	25V	70V	70V
Wattage	UL Rated*	Typical	UL Rated*	Typical
¼ W	80 dBA	80.7 dBA	80 dBA	81.1 dBA
½ W	84 dBA	83.7 dBA	84 dBA	83.5 dBA
1 W	87 dBA	87.1 dBA	87 dBA	87.2 dBA
2 W	90 dBA	90.1 dBA	91 dBA	90.2 dBA

*Sound level output notes:

dBA = Decibels, A-weighted

UL1480: Sound level output at 10 ft (3.05 m) measured in a reverberant room using 400 to 4,000 Hz band limited pink noise.

ULC-S541: Meets or exceeds 85 dBA in an anechoic chamber at 10 ft (3.05 m).

Directional characteristics: Within 6 dB of on-axis sound level when measured 90° off-axis (horizontal).
