Maple Armor FW2971 Addressable / Conventional Audible Notification Horn (7 Selectable dBA Levels)

Description

The Maple Armor FW2971 Audible Notification Horn is a high-performance indoor acoustic signaling appliance engineered to provide crisp, high-penetration emergency evacuation tones for commercial, institutional, and industrial facilities.

Designed with versatile dual-mode circuitry, this audible device operates seamlessly on conventional 24 VDC notification appliance circuits (NACs) as well as within intelligent addressable signaling networks powered by Maple Armor FW2105 and FW2107 control panels.

Compliant with UL 464 and CAN/ULC-S525 life-safety standards, the Maple Armor FW2971 Audible Notification Horn delivers field-configurable decibel levels and multiple tone patterns to ensure clear acoustic warning throughout protected buildings.

High-Acoustic Clarity & Precision Field-Configurable Output

The primary advantage of the Maple Armor FW2971 Audible Notification Horn is its high-efficiency acoustic driver.

By producing high sound pressure levels while drawing minimal current from the notification circuit, this horn enables fire system designers to power more appliances per circuit and utilize smaller wiring gauges without causing severe end-of-line voltage drops.

Commissioning engineers can easily set the required sound levels and tone sequences using rotary switches located behind the front housing. The 7-step dBA selector allows exact calibration to match room reverberation profiles, ensuring the Maple Armor FW2971 Audible Notification Horn delivers distinct, intelligible emergency signaling in bustling mechanical rooms, quiet educational corridors, and large commercial halls.

• Selectable Output Volumes: Easily adjusted from 67 dBA to 93 dBA to meet local ambient noise requirements without over-alarming quiet spaces.
• Standardized Evacuation Tones: Built-in tone generator provides standard Temporal 3 for fire alarms and Temporal 4 for carbon monoxide threats.
• Zone Synchronization: Synchronizes horn output across entire notification zones when connected to compatible Maple Armor panels or sync modules.
• Fast Installation Base: Separate mounting plate allows contractors to pre-wire and check circuit continuity before clipping on the active horn unit.

Frequently Asked Questions (FAQ)

Q1: What sound output levels can be configured on the Maple Armor FW2971 Audible Notification Horn?
A: The FW2971 features 7 field-selectable acoustic volume levels ranging from 67 dBA up to 93 dBA @ 10 ft, easily set via an onboard rotary selector switch.

Q2: What emergency tone patterns does the horn support?
A: It supports industry-standard Temporal 3 (ANSI S3.41 emergency evacuation), Temporal 4 (gas/CO emergency), Continuous tone, and March Time patterns at 20, 60, and 120 beats per minute.

Q3: Can this horn operate on both addressable loops and conventional NAC lines?
A: Yes. The FW2971 is engineered with dual-mode architecture, allowing installation on standard conventional 24 VDC NAC circuits or direct integration with addressable Maple Armor systems.

Q4: What mounting electrical boxes are compatible with the FW2971?
A: It mounts directly to standard North American 1-gang, 2-gang, 4-inch square, or dedicated surface backboxes.

Q5: What certifications does the FW2971 hold?
A: The device is fully certified and listed under UL 464 (Audible Signaling Appliances) and CAN/ULC-S525 standards for fire protective signaling systems.

Q6: Which Maple Armor control panels support this notification horn?
A: It is fully compatible with Maple Armor Series 2 control panels, including the FW2105 multi-loop panel and the FW2107 dual-hazard releasing panel.
