Series ET-1010 and ET80 Vandal Resistant Speakers and Speaker Strobes

ET80

Description

The Wheelock Series ET Vandal Resistant speakers and
speaker strobes provide a full range of rugged, high performance
combinations specifially designed to meet the critical needs of
the life safety industry for voice and tone signaling. Available in
compact, aesthetically pleasing package styles, each ET model
covers both 25 and 70 volt audio systems, and has multiple
wattage taps from 1/8 to 8 watts. Their high-efficiency design
provides improved voice clarity and higher sound output for typical
low frequency fire evacuation signal, such as the “slow whoop”
and “temporal code-3”.

Series ET80 Speaker Strobes are designed to meet the latest
requirements of NFPA 72 (National Fire Alarm Code), ANSI

117.1 (American National Standard of Accessible and Usable
Buildings and Facilities) and UL Standard 1971 (Standard for
Signaling Devices for the Hearing Impaired) and UL Standard
1480 (Speakers for Fire Protective Signaling Systems).

Series ET80 Speaker Strobes are UL Listed for indoor use, wall
mount, under Standards 1971 and 1480 for Speaker Appliances,
and incorporate a Lexan® lens to provide maximum reliability for
effective visible signaling. Strobe options include Multi-candela
MCW strobes with field selectable 15/30/75/110 or MCWH strobes
with field selectable 135/185 candela. Single candela 1575
strobes (rated 15cd with 75 cd on axis) are also available.

Series ET80 Speaker Strobes, when used with Wheelock SM/DSM
Sync Modules or Wheelock Power Supplies produce synchronized
strobe flashes for compliance with ADA guidelines concerning
photosensitive epilepsy.

General Notes:

• Strobes are designed to flash at 1 flash per second minimum over their “Regulated Voltage Range”. Note that NFPA-72 specifies a flash rate of 1

to 2 flashes per second and ADA Guidelines specify a flash rate of 1 to 3 flashes per second.

• All candela ratings represent minimum effective Strobe intensity based on UL Standard 1971.

• “Regulated Voltage Range” is the newest terminology used by UL to identify the voltage range. Prior to this change UL used the

terminology “Listed Voltage Range”.

*UL max current rating is the maximum RMS current within the listed voltage range (16-33v for 24v units). For strobes
the UL max current is usually at the minimum listed voltage (16v for 24v units). For audibles the max current is usually

at the maximum listed voltage (33v for 24v units). For unfiltered FWR ratings, see installation instructions.
