GST DC-M9413R Conventional Wall Mount Sounder Strobe (UL Listed / FM Approved, Red)

Description

The GST DC-M9413R Conventional Wall Mount Sounder Strobe is a high-performance, dual-action fire alarm notification appliance engineered to deliver clear acoustic alerts and high-intensity optical warning signals across commercial, institutional, and industrial life safety systems. Designed specifically for indoor wall mounting, the GST DC-M9413R features a rugged red flame-retardant housing that integrates a high-output sounder with a multi-candela xenon strobe. Operating on standard 24 VDC nominal conventional notification circuits, it provides emergency audio-visual evacuation signaling to penetrate high ambient background noise and meet stringent life safety building mandates.

Multi-Candela Flexibility & UL 1971 Synchronized Evacuation Coverage

The engineering core of the GST DC-M9413R centers on its multi-tap optical strobe output paired with an energy-efficient acoustic sounder. Facility layouts frequently demand varying illumination intensities depending on room dimensions, corridor widths, and ambient light conditions. The GST DC-M9413R eliminates the need for stocking multiple single-candela inventory units by offering an on-board selector switch that allows field technicians to set the strobe intensity to 15 cd, 30 cd, 75 cd, or 110 cd. Once selected, the chosen candela rating remains clearly visible through a dedicated viewing window after the device is mounted to the wall, streamlining post-installation compliance inspections by fire marshals.

In facilities requiring hearing-impaired emergency notification compliance, the unit strictly follows UL 1971 performance criteria. The visual flasher maintains an exact 1 flash per second (1 fps) strobe frequency. When connected to a conventional fire alarm control panel NAC configured in sync mode—or routed through an external GST DC-M9410 Signal Synchronization Module—all interconnected sounder strobes fire in unison across common notification paths. This synchronization prevents optical disorientation caused by random, asynchronous flashes in large open areas and long hallways.

Installation efficiency is supported by a universal terminal interface engineered for standard 2-1/2-inch single-gang electrical boxes. The internal wiring terminals accept 18 AWG to 12 AWG conductors, supporting in-and-out loop terminations for supervision without wire breaks. Constructed from high-durability, flame-retardant red ABS plastic, the outer housing protects sensitive solid-state circuitry against accidental impacts, ambient airborne dust, and industrial room environments.

• Field-Configurable Multi-Candela Switch: Easily switch between 15, 30, 75, and 110 cd settings to accommodate small offices, large open bays, and high-traffic corridors.
• UL 1971 Optical Synchronization: Interlocks with synchronized NAC lines or signal sync modules to ensure uniform, simultaneous 1 fps visual alerting.
• Selectable Evacuation Tones & dB Levels: On-board dip switch configuration allows fine-tuning of acoustic decibels and tone types to optimize intelligibility.
• Universal Circuit Termination: Designed for standard 24 VDC / 24 VFWR conventional circuits with wide wire gauge support from 18 to 12 AWG.

Frequently Asked Questions (FAQ)

Q1: What is the main function of the GST DC-M9413R?
A: The GST DC-M9413R is a conventional wall-mount notification appliance that delivers simultaneous audible sound alerts and high-intensity visual flashing strobe alerts during fire alarm events.

Q2: What is the difference between model GST DC-M9413R and DC-M9413W?
A: The difference is housing color: the GST DC-M9413R is molded in high-visibility Red, whereas the DC-M9413W comes in White.

Q3: How do installers adjust the strobe candela rating?
A: The candela output is adjusted via an on-board selector switch to 15 cd, 30 cd, 75 cd, or 110 cd. The selected value remains visible through the front faceplate after installation.

Q4: Can this sounder strobe operate with synchronized flashing?
A: Yes. Synchronized operation is achieved by connecting the unit to a fire alarm control panel NAC output set to Synchronization Mode or by routing it through an external GST DC-M9410 Signal Synchronization Module.

Q5: What supply voltage does the GST DC-M9413R require?
A: It operates on nominal 24 VDC or 24 VFWR (Full Wave Rectified) conventional notification circuits.

Q6: What back box is compatible with this unit?
A: The unit mounts to a standard single-gang electrical back box with a minimum depth of 2-1/2 inches (64 mm).

Q7: What safety and regulatory listings does this product carry?
A: The GST DC-M9413R is UL Listed under UL 1971 (Signaling Devices for the Hearing Impaired) and UL 464 (Audible Signaling Devices), as well as FM Approved.
