Wheelock POWERPATH series PS-12-24-8MP User manual

DESCRIPTION
Wheelock’s Weatherproof Low Profile Speaker
Strobe, Series ET70WP appliances for wall and ceiling
mounting have an extended temperature range of
-31°F to 150°F (-35°C to 66°C) that will satisfy virtually
all outdoor and severe environment applications.
The Wheelock Weatherproof Speaker Strobe is
designed for maximum performance, reliability, and
cost effectiveness while meeting or exceeding the
latest requirements of NFPA 72 (National Fire Alarm
Code), UL Standard 1638 (Standard for Visual Signaling
Appliances), and UL Standard 1480 (Standard for
Speaker Appliances).
SERIES ET70WP
Mounted to IOB-R
• Approvals include: UL Standard 1638, UL Standard
1480, California State Fire Marshal (CSFM), and
New York City (MEA) Pending: Factory Mutual (FM)
and Chicago (BFP)
• Designed to meet or exceed NFPA/UFC/ANSI 117.1/
OSHA Part 29, 1910.165, and ADA requirements.
• UL Standard 1638 and UL Standard 464 listed
with extended temperature range of -31°F
to 150°F (-35°C to 66°C)
• 24 VDC with new UL “Regulated” Voltage Range:
16-33 VDC using filtered DC or unfiltered FWR voltage
• Sync/Non-Sync strobe. Synchronize strobe with
Series SM, DSM Sync Modules or PS-12/24-8CP
and PS-12/24-8MP Power Supplies with built-in
patented sync protocol
• IN and OUT wiring termination that accepts two
#12-18 AWG wires at each terminal
• Inputs are polarized for compatibility with industry
standard reverse polarity supervison
The strobe has a 75 candela intensity on axis at -31°F
(-35°C) and 180cd at 77°F (25°C) with low current
draw. For outdoor applications the ET70WP–2475W-
FR must be wall mounted to a Weatherproof Back Box
(IOB). The speakers are designed for multiple power
requirements with high dBA output at each power tap.
The low profile model offers a choice of field selectable
taps, 1/8W to 8W for either 25.0 VRMS or 70.0 VRMS
audio systems. The low profile design incorporates
a high efficiency speaker for maximum output at
minimum power across a frequency range of 400 Hz
to 4000 Hz and features a sealed back construction
for extra protection and improved audibility. The low
profile speaker strobes can provide non-synchronized
operation when directly connected to the Fire Alarm
Control Panel, or synchronized strobe operation when
used in conjunction with a Wheelock Sync Module
(SM), Dual Sync Module (DSM), or Wheelock Power
Supplies (PS-12/24-8CP and PS-12/24-8MP) with built-
in patented sync protocol. The strobes use a Xenon
flashtube with solid state circuitry enclosed in a rugged
Lexan lens to provide maximum visibility and reliability
for effective visible signaling.

WARNING: PLEASE READ THESE SPECIFICATIONS AND ASSOCIATED INSTALLATION INSTRUCTIONS CAREFULLY
BEFORE USING, SPECIFYING OR APPLYING THIS PRODUCT. FAILURE TO COMPLY WITH ANY OF THESE INSTUCTIONS,
CAUTIONS, OR WARNINGS COULD RESULT IN IMPROPER APPLICATION, INSTALLATION, AND/OR OPERATION OF THESE
PRODUCTS IN AN EMERGENCY SITUATION, WHICH COULD RESULT IN PROPERTY DAMAGE, AND SERIOUS INJURY OR
DEATH TO YOUAND/OR OTHERS.
General Notes:
•Wheelock UL 1638 Strobes are designed to produce 30-62 flashes per minute over the Regulated Voltage Range. If used in an indoor application,
UL 1638 strobes must be operated at a minimum of 20 VDC to meet the NFPA-72 (1999) flash rate of 1 to 2 flashes pers second and ADA Guideline
flash rate of 1 to 3 flashes per second.
•Wheelock Weatherproof Appliances are designed to operate over an extended temperature range of -31°F to 150°F (-35°C to 66°C) and all candela
ratings represent minimum effective strobe intensity based on UL 1638. Maximum humidity of 93% RH ± 2%.
•“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”.

* RMS current ratings are per UL average RMS
method. 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.

ARCHITECTS AND ENGINEERS SPECIFICATIONS
WEATHERPROOF SERIES ET70WP
The Weatherproof Low Profile Speaker Strobe shall be Wheelock Series ET70WP for wall and ceiling applications or
approved equal. The Series ET70WP shall meet and be listed for UL Standard 1638 (Standard for Visual Signaling
Appliances) for Indoor/Outdoor use, Fire Protective Service and UL Standard 1480 (Standard for Speaker Appliances.
The strobe portion of the ET70WP shall produce a flash rate of 30-62 flashes per minute over the Regulated Voltage
Range of 16 to 33 VDC and shall incorporate a Xenon flashtube enclosed in a rugged Lexan lens to provide maximum
visibility and reliability for effective visible signaling. The strobe shall be rated 180cd @ 77°F (25°C) and 75cd at -31°F
(-35°C) and shall operate over an extended temperature range at -31°F to 150°F (-35°C to 66°C) and be listed for
maximum humidity at 95% RH. For outdoor applications the ET70WP shall be wall mounted to a weatherproof back
box (IOB). The speakers shall be designed for multiple power requirements with a high dBA output at each power tap.
The low profile model shall offer a choice of field selectable taps, 1/8W to 8W for either 25.0 VRMS or 70.0 VRMS
audio systems. The low profile design shall incorporate a high efficiency speaker for maximum output at minimum
power across a frequency range of 400Hz to 4000Hz and features a sealed back construction for extra protection
and improved audibility. When synchronization of the strobe is required, the strobe portion of the appliance shall be
compatible with Wheelock’s SM, DSM sync modules or Wheelock’s PS-12/24-8CP and PS-12/24-8MP Power Supplies
with built-in Patented Sync Protocol. If the sync module or syncprotocol in the Power Supply shall fail to operate (i.e.,
contacts remain closed), the strobe shall revert to a non-synchronized flash rate.
