Architects and Engineers Specifications
The LED notification appliances shall be Wheelock® ELHS audible
visual strobe appliances, ELST visual strobe appliances and ELHN
audible appliances for wall and ceiling-mount applications with a low-
profile design or approved equals. Special lettering, including AGENT,
ALERT, EVACUATE, and no lettering, shall be available. The ELHS
and ELST strobes shall be listed for UL Standard 1971 (Emergency
Devices for the Hearing-Impaired) for Indoor Fire Protection Service
and UL 1638 (Visible Signaling Devices. The ELHS and ELHN
Audibles shall be UL Listed under Standard 464 (Fire Protective
Signaling). All models shall meet the requirements of FCC Part 15
and ICES-003. All inputs shall be compatible with standard reverse
polarity supervision of circuit wiring by a Fire Alarm Control Panel
(FACP) with the ability to operate from 16 to 33 VDC/VFWR.
The ELHS audible strobe and ELST strobe appliances shall produce
a flash rate of one (1) flash per second over the Regulated Voltage
Range and shall incorporate a Light Emitting Diode (LED) as the
light source with a rugged Lexan® lens. The appliances shall be of
low current design. The LED strobe flash duration shall be 20 ms.
Where Multi-Candela appliances are specified, the strobe intensity
shall have 6 field selectable settings at 15, 30, 75, 110, 135 and 185
candela for wall mount applications and 15, 30, 75, 110, 150 and 177
for ceiling applications. The selector switch for selecting the candela
shall be tamper resistant. Appliances with candela settings shall
show the candela selection in a visible location at all times when
installed.
The audible shall have a choice of three (3) horn patterns (high & low
output): Continuous, T3, and T3/T4 for fire (T3) and CO (T4) signaling.
The ELHS audible strobe, ELST strobe, and ELHN audible shall
include a hinged mounting plate. Mounting options shall include
LED backboxes, single-gang backbox and to 4” square with adapter
kit for wall-mount models and LED Ceiling backboxes and 4” square,
1 1/2” or 2 1/8”deep for ceiling models. Two wire appliance wiring
shall be capable of directly connecting to the mounting base.
Removal of an appliance shall result in a supervision fault condition
by the Fire Alarm Control Panel (FACP). All notification appliances
shall be backwards compatible.
The ELHS, ELHN and ELST wall models shall have a low profile
measuring 4.79”H x 2.76”W x 1.18”D. The ELHSC, ELHNC and
ELSTC ceiling models shall have a low profile measuring 6.27”
Diameter with 1.69”D.
When synchronization is required, the appliance shall be compatible
with Wheelock®’s DSM Sync Modules, PS Power Supplies,
SAFEPATH products or other manufacturer’s panels with built-in
Wheelock® Patented Sync Protocol. The strobes shall not drift out
of synchronization at any time during operation. If the sync protocol
fails to operate, the strobe shall revert to a non-synchronized flash-
rate and still maintain (1) flash per second over its Regulated Voltage
Range. The appliance shall also be designed so that the audible
signal may be silenced while maintaining strobe activation when
used with Wheelock® patented sync protocol.
