ARCHITECT & ENGINEER SPECIFICATIONS

The speaker appliances shall be Wheelock ET Series Speakers and Speaker Strobes or approved equivalent. The speakers shall

be listed under Standard UL 1480 for Fire Protective Service. Speaker appliances equipped with strobes shall additionally be Listed

under UL 1971, Signaling Devices for the Hearing Impaired.

output up to 94 dBA for speakers and speaker-strobes. Strobes shall be Listed for 20 to 31 VDC input using filtered power or unfil-

Out field wiring using terminals that accept #12 AWG (3.25 mm²) to #18 AWG (0.75 mm²) wiring. Additionally, the speaker shall

incorporate sealed-back construction.

Combination speaker-strobe appliances shall incorporate a Xenon flashtube enclosed in a rugged LEXAN® lens or equivalent with

solid state circuitry. Strobe shall meet UL 1971 and produce a flash rate of one (1) flash per second minimum over the listed input

voltage (20 - 31 VDC) range. The strobe intensity shall be rated per UL 1971 for 15, 15/75, 30, 75, or 110 candela for wall mounting;

and 15, 30, 75, or 100 candela for ceiling-mount applications. The 15/75 candela wall strobe shall be specified when 15 candela UL

1971 listing with 75 candela intensity on-axis is required.

Combination speaker-strobe appliances shall incorporate the Wheelock RSS Series Non-Sync/Sync circuitry and shall be designed

for compatibility with Wheelock SM and DSM Sync Modules for synchronized strobe flash. Wheelock Sync Modules and Synchronized

Strobes shall be designed as a system for continuous activation of the strobes; should the Sync Module contacts fail in the passive

state (i.e., contacts remain closed), the strobes shall revert to a non-synchronized rate of 1 flash per second (default mode).

All UL 1971 listed strobe appliances shall be certified to meet FCC Part 15, Class B and incorporate low temperature compensation

to ensure the lowest possible current consumption. Strobe activation shall be via independent input from the audio circuit.

The speakers and speaker-strobe appliances shall be designated for indoor surface or flush mounting. The speaker and speaker

strobes shall incorporate a speaker mounting plate with a grille cover which is secured with two screws for a level, aesthetically

pleasing finish. They shall mount on standard electrical hardware requiring no additional trim plate or adapter. The appliance shall be

finished in a textured red or white color.

Contact Wheelock for installation instructions (Wheelock P83567) and general information sheet (Wheelock P82380) for these products.

These materials undergo periodic changes. It is important that you have current information on these products. These materials contain

important information that should be read prior to specifying or installing these products, including:

•

Total current required by all devices connected to system primary and secondary power sources.

•

Fuse ratings on NAC circuits to handle maximum inrush or peak currents from all devices on those circuits.

•

Composite flash rate from multiple strobes within a person’s field of view.

•

Voltage applied: the voltage applied to these products must be within their rated input voltage range.

•

Installation of 110/100 candela strobe products in sleeping areas.

•

Installation in office areas and other specification and installation issues.

•

Note: Use strobes only on circuits with continuously applied operating voltage. Do not use strobe on coded or interrupted

nac circuits in which the applied voltage is cycled on and off, as the strobe may not flash.

•

Conductor specifications: Conductor size (AWG), length and capacity should be taken into consideration prior to design and

installation of these products, particularly in retrofit installations.

FAILURE TO COMPLY WITH THE INSTALLATION INSTRUCTIONS OR GENERAL INFORMATION SHEETS COULD RESULT IN

IMPROPER INSTALLATION, APPLICATION, AND/OR OPERATION OF THESE PRODUCTS IN AN EMERGENCY SITUATION, WHICH

COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

Wheelock products must be used within their published specifications and must be PROPERLY specified, applied, installed, operated,

maintained, and operationally tested in accordance with their installation instructions at the time of installation and at least twice a year

or more often and in accordance with local, state, and federal codes, regulations, and laws. Specification, application, installation,

operation, maintenance, and testing must be performed by qualified personnel for proper operation in accordance with all of the latest

National Fire Protection Association (NFPA), Underwriters’ Laboratories (UL), National Electrical Code (NEC), Occupational Safety and

Health Administration (OSHA), local, state, county, province, district, federal, and other applicable building and fire standards, guide-

lines, regulations, laws, and codes including, but not limited to, all appendices and amendments and the requirements of the local

authority having jurisdiction (AHJ).
