Simplex 49AO-WRF Addressable Sounder

Description

The Simplex 49AO-WRF Addressable Sounder is a next-generation TrueAlert ES audible notification appliance engineered to provide high-integrity, addressable emergency signaling across modern life-safety networks. Controlled and supervised directly over an intelligent IDNAC Signaling Line Circuit (SLC), this advanced indoor electronic horn provides location-specific diagnostics and high-performance audio projection. Housed in a rugged, impact-resistant red thermoplastic cover featuring bold white “FIRE” markings, it delivers a loud, penetrative alarm tone that ensures immediate attention across commercial, institutional, and industrial real estate complexes.

TrueAlert ES Intelligent Operations & Automated Self-Test Diagnostic Advantages

The defining operational benefit of the Simplex 49AO-WRF Addressable Sounder is its integration with TrueAlert ES technology running on IDNAC loops. Unlike traditional notification circuits where an entire wire line must be tested manually, the 49AO-WRF features an advanced, automated Self-Test mode. Armed with internal acoustic sensors, the device tests its own horn output circuitry and reports back to the central console panel automatically.

• Dual Output Level Settings: Features switch-selectable configuration parameters to alternate between High and Low volume outputs, giving an absolute 6 dBA adjustment range to meet localized room acoustics.
• Latching Cadence Control: The horn operates completely independently from visible strobes on the same loop, responding instantly to panel commands for Temporal Code 3, March Time (60 BPM), or continuous tones.
• Rear-Zero Enclosure Footprint: The specialized clean back profile does not extend into the electrical gang box, leaving maximum workspace inside the wall box for heavy field wiring loops.
• Polarized Supervision Network: Built with a diode-polarized configuration to enforce strict loop wiring supervision, ensuring any downstream open faults are reported instantly to the control interface.

Frequently Asked Questions (FAQ)

Q1: What unique workflow benefit does the TrueAlert ES Self-Test feature offer?
A: It utilizes built-in internal sensors to physically test the sounder mechanism and report results back to the central panel, allowing for automated diagnostic sweeps without requiring manual room-by-room walkthroughs.

Q2: Can the 49AO-WRF addressable sounder be wired onto the same circuit as loop strobes?
A: Yes. Operating on an IDNet or IDNAC two-wire loop, it can share a single pair of circuit wires with visual appliances while allowing the panel to silence the horn independently while strobes remain flashing.

Q3: How do technicians physically check the assigned address code of this sounder in the field?
A: By placing a standard test magnet near the designated bottom area of the housing, the diagnostic LED will pulse out the exact binary loop address assigned to that specific unit.

Q4: Is an independent auxiliary 24V power line required to run this addressable sounder?
A: No. Operating current, system commands, and diagnostic telemetry are drawn entirely over the two-wire IDNAC circuit, which supplies a constant, regulated 29 VDC output loop.

Q5: Can the acoustic sound level be lowered for small office spaces or echoing stairwells?
A: Yes. You can toggle the output volume level from High down to Low via internal configuration switches, or install an optional 4905-9838 mechanical sound damper to drop output by an extra 5 to 6 dBA.

Q6: Which central fire alarm control panels natively drive this addressable notification appliance?
A: It integrates natively with modern addressable Simplex control units equipped with IDNAC channels, including the 4007ES, 4010ES, and 4100ES platform series.

Q7: What type of box mounting does this red wall sounder support?
A: The low-profile chassis template attaches securely to standard single-gang, double-gang, or 4-inch square electrical backboxes for easy surface or semi-flush wall installation.
