Simplex 49AV-WRF Addressable Sounder with Strobe

Description

The Simplex 49AV-WRF Addressable Sounder with Strobe is a next-generation TrueAlert ES audible/visible (A/V) notification appliance engineered to provide high-integrity emergency signaling within modern commercial, industrial, and institutional safety infrastructures. Controlled and supervised directly over an intelligent IDNAC Signaling Line Circuit (SLC), this advanced wall-mount unit combines a clear xenon flash strobe and an efficient electronic horn chamber into a sleek, low-profile thermoplastic assembly.

TrueAlert ES Operation Edge & Automated Self-Test Diagnostic Advantages

The defining operational benefit of the Simplex 49AV-WRF Addressable Sounder with Strobe is its integration with TrueAlert ES technology running on modern IDNAC loops. Unlike traditional notification circuits where an entire wire branch must be tested manually by field crews, the 49AV-WRF features an advanced, automated Self-Test mode. Armed with internal optical and acoustic sensors, the device triggers its own strobe flash and horn mechanics briefly and reports the operational results back to the central fire alarm control panel automatically.

• Six-Tier Candela Adjustability: Offers full flexibility across changing room layouts by allowing the strobe intensity to be set to 15, 30, 75, 110, 135, or 185 cd via backend jumper pins or central panel commands.
• 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 (selectable at 20, 60, or 120 BPM), or continuous tones.
• Front-Accessible Wiring Terminal Plate: Features a design where the backplate wiring can be terminated completely before mounting the main electronic housing, protecting sensitive components during rough-in construction.
• Polarized Supervision Network: Built with a diode-polarized configuration to enforce strict loop wiring supervision extending all the way into the device’s electronic circuit, ensuring any open faults are reported instantly.

Frequently Asked Questions (FAQ)

Q1: How can an inspector verify the selected strobe candela rating without detaching the module?
A: The module features an integrated strobe intensity viewing slot on the side of the housing cover, allowing inspectors to easily check the active candela output at a glance.

Q2: Does this combination appliance require separate wiring loops for the horn and the strobe elements?
A: No. Operating on an IDNAC two-wire loop, both appliances share a single pair of wires, allowing the panel to silence the horn independently (“on-until-silenced”) while the strobe remains flashing (“on-until-reset”).

Q3: What unique workflow advantage does the TrueAlert ES Self-Test feature offer?
A: It utilizes built-in internal sensors to physically check the sounder and flash mechanisms and report results back to the panel, allowing for automated diagnostic sweeps without manual room-by-room walkthroughs.

Q4: Is an independent auxiliary 24V power line circuit run required to power this module?
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 even during battery backup.

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 (providing an absolute 5 dBA reduction), or install an optional mechanical sound damper.

Q6: Which central fire alarm control panels provide native support for this addressable 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 combination unit support?
A: The flexible mounting template attaches securely to standard single-gang, double-gang, or 4-inch square electrical backboxes for easy surface or semi-flush wall installation.
