Maple Armor FW2501 4-Inch Standard Addressable Fire Detector Base

Description

The Maple Armor FW2501 Addressable Detector Base is a rugged, high-reliability 4-inch mounting base engineered to provide seamless electrical interconnection and secure physical seating for Maple Armor Series 2 intelligent sensors. Designed for streamlined field deployment across commercial, institutional, and industrial facilities, the Maple Armor FW2501 Addressable Detector Base connects directly to the Signaling Line Circuit (SLC) loop of FW2105 and FW2107 fire alarm control panels. Featuring heavy-duty clamping terminals and an integrated twist-lock mechanism, the Maple Armor FW2501 Addressable Detector Base ensures continuous loop integrity even when detector heads are removed for servicing or testing.

Twist-Lock Ease of Installation & Anti-Tamper Security

The core structural advantage of the Maple Armor FW2501 Addressable Detector Base is its intuitive twist-lock design. During rough-in construction, electrical contractors can wire and test all SLC loop circuits directly on the base terminals. Once painting and dust-generating site work are completed, commissioning technicians simply push and rotate the detector head clockwise into the Maple Armor FW2501 Addressable Detector Base until it locks securely into place.

To safeguard public facilities against unauthorized removal or vandalism, each base includes an integral breakable locking tab. When activated, the detector head cannot be removed without inserting a specialized small flathead tool into the release slot, maintaining continuous life-safety protection in schools, hotels, residential corridors, and commercial offices.

• Effortless Head Swapping: Twist-lock terminal contact allows detector inspection, cleaning, and testing without interrupting or disconnecting field cables.
• Remote Alarm Output Support: Equipped with dedicated screw posts that power external FW2561-RI LED indicator plates in concealed ceiling voids.
• Universal Box Fit: Wide elongated mounting slots accommodate standard North American electrical backboxes without additional adapter plates.
• Rugged Terminal Plates: High-torque screw terminals prevent wire loosening from structural vibrations in industrial mechanical rooms.

Frequently Asked Questions (FAQ)

Q1: Does the Maple Armor FW2501 base contain electronic address settings?
A: No. The FW2501 is a passive universal mounting base. The digital address is stored directly inside the microprocessor of the plug-in detector head (such as the FW2511 or FW2521), allowing easy replacement of sensor heads without rewiring the base.

Q2: Which detector models can be plugged into the Maple Armor FW2501 base?
A: The FW2501 standard base is fully compatible with Maple Armor Series 2 detectors, including the FW2511 Photoelectric Smoke Detector and the FW2521 Fixed/Rate-of-Rise Heat Detector.

Q3: Does this base support wiring to a remote LED indicator lamp?
A: Yes. The base includes dedicated auxiliary terminals (LED+ and GND) designed to power the Maple Armor FW2561-RI Remote LED Indicator plate.

Q4: What size junction boxes are compatible with the FW2501?
A: It mounts directly to standard North American 1-gang electrical boxes, 3-1/2-inch octagonal boxes, and 4-inch octagonal electrical junction boxes.

Q5: How do I lock the detector head to prevent tampering?
A: The base features an integrated molded locking tab. Once the detector head is turned past the lock point, it cannot be uninstalled without releasing the tab with a small screwdriver.
