wheelock E-70, E-90 Service Manual

FIRE ALARM SYSTEMS

Description

Wheelock’s Series E Speakers and Speaker Strobes are
designed to meet the critical needs of the life safety
industry for effective emergency voice communications
and tone signaling. Series E speakers provide high audio
output with clear audibility at minimum wattage. They
offer system designers the high quality , high performance
and low installed cost required for fire protection systems.
All models flush mount to electrical backboxes and are
equipped with a blocking capacitor for DC supervision of
audio lines and IN/OUT wiring terminals for fast installation
using #12 to #18 AWG wiring.

Series E Speaker Strobes are ULC Listed for indoor use,
ceiling and wall mount, and use a Xenon flashtube with
solid state circuitry enclosed in a rugged Lexan® lens to
provide maximum reliability for effective visible signaling.

#dBA ratings are based on UL testing under Standard UL 1480

WARNING: AL THOUGH ULC TESTING HAS VERIFIED THA T THESE STROBES FUNCTION EVEN A T 80% OF THEIR MINIMUM RA TING AND
110% OF THEIR MAXIMUM RA TING, WHEELOCK STRONGLY RECOMMENDS THA T THE VOL T AGE APPLIED TO THESE PRODUCTS BE
WITHIN THEIR RATED INPUT VOLTAGE RANGE. THE APPLICATION OF IMPROPER VOLTAGE MA Y RESUL T IN DEGRADED OPERA TION OR
DAMAGE TO THESE PRODUCTS.

The ULC Listed “Rated Input Voltage” uses either filtered (DC) or unfiltered full-wave-rectified (FWR) volt age. Check the minimum and maximum output
of the power supply and standby battery and subtract the voltage drop from the circuit wiring resistance to determine the applied voltage to the strobes.

Use the highest value of rated average current to determine the maximum number of strobes and to establish power supplies and wire gauge require­ments. Use the rated peak current or rated inrush current (whichever is higher) to verify fuse requirements.

Make sure that the average, peak and inrush currents do not exceed system power supplies or fusing limits. See “Installation Instructions”.

WARNING: CONT ACT WHEELOCK FOR “INST ALLA TION INSTRUCTIONS” AND “GENERAL INFORMA TION” SHEET ON THESE PRODUCTS.
THESE MATERIALS CONT AIN IMPORT ANT INFORMA TION THA T SHOULD BE READ PRIOR T O SPECIFYING OR INST ALLING THESE
PRODUCTS, INCLUDING:

• TOT AL CURRENT REQUIRED BY ALL APPLIANCES CONNECTED T O SYSTEM SECONDARY POWER SOURCES

• FUSE RATINGS ON NAC CIRCUITS T O HANDLE MAXIMUM INRUSH OR PEAK CURRENTS FROM ALL APPLIANCES ON THOSE NAC
CIRCUITS. THE TIME DURATION OF THE MAXIMUM STROBE INRUSH OR PEAK CURRENT IS 2 MILLISECONDS FOR LS

• INST ALLATION IN OFFICE AREAS AND OTHER SPECIFICATION AND INSTALLA TION ISSUES

General Notes:

• Strobes are designed to falsh at 1 flash per second minimum

• Series E Speaker Strobes are Listed for indoor use with a temperature range of 0°C to 49°C (32°F to 120°F) and maximum humidity of 95%RH.

WARNING: USE STROBES ONL Y ON NAC CIRCUITS WITH CONTINUOUSLY APPLIED OPERATING VOLTAGE. DO NOT USE STROBES ON
CODED OR INTERRUPTED NAC CIRCUITS IN WHICH THE APPLIED VOL T AGE IS CYCLED ON AND OFF , AS THE STROBE MA Y NOT FLASH.
