Addressable Strobe & Horn

Model Series 49AV TrueAlert Addressable Notification Appliances

TrueAlert ES addressable A/Vs are individually addressed audible/ visible notification appliances that receive power, supervision, and control signals from a Simplex fire alarm control panel providing IDNAC Signaling Line Circuits (SLCs). See TrueAlert ES A/V LEGACY Compatibility Reference for more detail.

Strobe Application Reference Proper selection of visible notification is dependent on occupancy, location, local codes, and proper applications of: 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).

Individually addressed and controlled multi-candela TrueAlert ES A/V (audible/visible) notification appliances provide:

  • Multi-candela xenon strobe with synchronized 1 Hz flash rate and with intensity programmable from the control panel or jumper selected as 15, 30, 75, 110, 135, or 185 cd
  • Advanced addressable notification controlled by IDNAC SLCs providing regulated 29 VDC allowing strobes to operate with lower current even under battery backup
  • Wiring supervision to each appliance allowing “T-tapped” connections for Class B circuits to simplify wiring (Class A circuits require in/out wiring)
  • Self-Test Mode allows on-board sensors to detect the strobe and horn output and then report their status to the control panel
  • TrueAlert Device Reports Reports are available at the control panel detailing appliance point ID, custom label, type, and candela setting
  • Magnet Test diagnostics Magnet Test diagnostics assist checkout and testing of appliances and wiring.
  • Electrical test point access Access the electrical test point without removing cover
  • Compatibility with ADA requirements; (refer to Installation Reference)
  • Compatibility with legacy TrueAlert addressable systems for upgrade and replacement
  • Strobe operation is listed to UL Standard 1971 and ULC Standard S526; Horn operation is listed to UL Standard 464 and ULC Standard S525

LED Indicator and Magnet Test

  • Appliance LED can be selected to display each polling cycle to indicate appliance supervision
  • When the controller is in diagnostic mode, the Magnet Test pulses the LED to indicate appliance address and can be set to also briefly flash the strobe and sound the horn

Mechanical design features

  • Rugged, high impact, flame retardant thermoplastic housing in red with white letters or white with red letters, with clear lens, available with FIRE, FEU, ALERT, FEU/FIRE, or blank lettering
  • Separate covers are available to change application type on-site or for replacement
  • A separate mounting plate allows wiring to be completed before appliance is mounted; use with single gang, double gang, or 4-inch square box, flush or surface mount
  • Covers can be easily removed without disturbing the connected housing and avoiding trouble conditions
  • In/out wiring terminals for 18 AWG to 12 AWG
  • Optional mounting adapters are available to cover surface mounted electrical boxes and to adapt to Simplex, 2975-9145 boxes
  • Optional red wire guards See Product Selection for details.

Audible notification appliance (horn)

  • Harmonically rich output sound for either coded or steady operation
  • Horns sound as Temporal Code 3, March Time pattern, continuous; or Temporal Code 4, controlled separately from visible appliances on the same two-wire circuit
  • Selectable March Time rates of 20, 60, or 120 beats per minute
  • Output is “high” or “low” (~5 dBA difference) selectable at the appliance or from the controller with FACP mode selected at the appliance

TrueAlert ES addressable appliances on IDNAC SLCs provide separate visible and audible 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 VDC 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 and secondary 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 Self-Test and Magnet Test features improve installation efficiency. TrueAlert device reports
conveniently identify information about each connected appliance.

Test Features
When IDNAC SLCs are in diagnostic mode, Self-Test and Magnet Test features provide individual appliance testing. With the Self-Test feature, appliance
operation can be confirmed without leaving the control panel. Additionally, each appliance’s LED can be selected to pulse when it receives a supervision
poll during normal operation.

Self-Test Details
Selecting Self-Test Mode from the control panel allows on-board sensors, depending on the device type, to detect its own strobe and/or horn output
and then report their status to the control panel. Operation is by selected VNAC appliance groups and is either automatic (all briefly simultaneously
activated) or individually activated by applying a magnet. (Refer to control panel data sheet for more Self-Test information, see TrueAlert ES A/V LEGACY
Compatibility Reference for more information.

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

Operational Appliance Magnet Test
In this test mode, after the address is indicated by pulsing the appliance LED, the strobe will briefly flash and the horn will briefly sound 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 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.

Isolator Model 4905-9929 is available for remote mounting on TrueAlert addressable circuits to isolate short circuited wiring from functioning wiring. See data sheet S4905-0001 for information.
