UL, ULC, CSFM Listed* Dual Emergency Communication

Appliances, Clear/Amber Strobes

Features

Individually addressed and separately controlled
multi-candela V/O (visible only) notification
appliance with one amber ALERT strobe and one
clear lens FIRE strobe provides:

 Combination unit allows mounting two visible

notification appliances at the same installation site

 Multi-candela xenon strobes with synchronized 1 Hz

flash rate and with intensity programmable from the
control panel or jumper selected as 15, 30, 75, or
110 cd

 Advanced addressable notification controlled by IDNAC

SLCs from Simplex

with EPS/EPS+ power supplies (and 4009 IDNAC
Repeaters) providing regulated 29 VRMS allowing
strobes to operate with lower current even under
battery backup

 Amber lens with “ALERT” lettering produces a signal

unique from clear lens fire alarm evacuation strobes for
use with Emergency Communications Systems

 Clear lens with “FIRE” lettering provides visible

notification for fire alarm conditions

 Both strobes connect on same SLC, are separately

addressed, and provide independent operation;
(Operation is clear/Fire OR amber/Alert, not both)

 Wiring supervision to each strobe allowing

“T-tapped” connections for Class B circuits to
simplify wiring (Class A circuits require in/out
wiring)

 TrueAlert Device Reports at the control panel

detailing appliance point ID, custom label, type, and
candela setting (see sample on page 2)

 Magnet test diagnostics to assist checkout and testing

of appliances and wiring

 Compatibility with ADA requirements; (refer to

important installation information on page 3)

 Compatibility with legacy TrueAlert addressable

systems for upgrade and replacement (see page 4)

 Clear lens strobe is UL listed to Standard 1971, ULC

listed to Standard S526

 Amber lens strobe is UL listed to Standard 1638 (due to

non-white lens); and provides light dispersion patterns of
UL Standard 1971; ULC listing is to Standard S526

LED indicator and magnet test feature:

 Each appliance LED can be selected to display each

polling cycle to indicate appliance supervision

 In diagnostic mode, the magnet test pulses the LED to

indicate appliance address AND pulses to indicate the
intensity selection; a brief output of the strobe is also
selectable to confirm operation

mounting and box adapter plates

Description

Multi-Candela TrueAlert addressable combination
strobes are individually addressed and individually

controlled with power, supervision, and control supplied
from a Simplex fire alarm control panel providing IDNAC
Signaling Line Circuits (SLCs). (See compatibility list on
page 4.) A single assembly provides an amber lens strobe for
non-fire alarm, alert notification for use with Emergency
Communications Systems, and a clear lens strobe for fire
alarm notification.

Strobe Application Reference

Amber strobes used as part of an Emergency
Communications system are located to provide the same
area coverage as required of clear lens fire alarm strobes.
Specific Emergency Communications requirements are
discussed in detail in document UFC 4-021-01 (USA
Department of Defense, United Facilities Criteria) and in
NFPA 72, Chapter 24 (2010 and 2013 editions).

Proper strobe coverage criteria is further described in the
National Fire Alarm Code (NFPA 72), ANSI A117.1; the
appropriate model building code: BOCA, ICBO, or SBCCI;
and the application guidelines of the Americans with
Disabilities Act (ADA).

IDNAC SLC Operation Advantage

TrueAlert V/O Appliances with Addressable
Strobes on IDNAC SLCs provide visible notification

using a single two-wire circuit that also confirms
connection to the individual notification appliance’s
electronic circuit. This operation increases circuit

supervision integrity by providing supervision that
extends beyond the appliance wiring connections.

Reduced current allows efficient IDNAC SLC
operation. With IDNAC SLCs, a constant 29 VRMS

source voltage is maintained, even during battery standby,
allowing strobes to operate at higher voltage with lower
current and ensuring a consistent current draw and voltage
drop margin under both primary power an d seco ndary
battery standby. Efficiencies include wiring distances up to
2 to 3 times farther than with conventional notification, or
support for more appliances per IDNAC SLC, or use of
smaller gauge wiring, or combinations of these benefits, all
providing installation and maintenance savings with high
assurance that appliances that operate during normal system
testing will operate during worst case alarm conditions.

Reducing Installation and Testing Time. With
separate controls on the same two-wire SLC, installation
time and expense for both retrofit and new construction
can be significantly reduced. When Class B wiring is
used, wiring can be “T” tapped, allowing more savings in
distance, wire, conduit (size and utilization), and overall
installation efficiency. Use of the magnet test feature
improves installation efficiency. TrueAlert device reports
conveniently identify information about each connected
appliance.

By providing an amber lens strobe with a clear lens
strobe, the combination strobe assembly allows a single
electrical installation to provide both types of visible
notification.

TrueAlert Addressable Diagnostics

Test Features. Controllers can be selected to pulse each

appliance’s LED when it receives a supervision poll. When
the controller is selected for diagnostic mode, the appliance
magnet test feature provides a response at the individual
appliance being tested.

Silent Appliance Magnet Test. In this test mode, in
response to the magnet test, the appliance LED pulses
sequentially to conveniently indicate the appliance’s
address.

Operational Appliance Testing. In this test mode, after
the address is indicated by pulsing the appliance LED, the
strobe will briefly flash to indicate proper operation.

TrueStart Instrument Two (TSIT). The 2nd generation
of the Simplex TrueStart Test Instrument adds testing of
IDNAC SLC wiring and TrueAlert (and TrueAlert ES)
appliances to its ability to test IDCs, NACs, and IDNet
communications before connection to the control panel.
Please contact your local Simplex representative for
additional information.

TrueAlert Addressable Wiring Isolator

Isolator Model 4905-9929 is available for remote

mounting on TrueAlert addressable circuits to isolate short
circuited wiring from functionin g wi ri n g. (R efer t o dat a
