Maple Armor FW2733 Addressable Fire Suppression Maintenance Disconnect Switch (Stainless Steel)

Description

The Maple Armor FW2733 Addressable Disconnect Switch is an intelligent life-safety maintenance interface engineered to isolate automated extinguishing circuits during routine testing, inspection, and servicing.

Operating seamlessly on the Signaling Line Circuit (SLC) of the Maple Armor FW2107 releasing panel, this switch occupies a single digital address. When turned to the disconnect position, it physically breaks the release path to preventing accidental solenoid tripping and gas discharge across protected data centers, server rooms, and battery storage halls.

Compliant with UL 864, CAN/ULC-S527, and NFPA 2001 standards, the Maple Armor FW2733 Addressable Disconnect Switch features a trapped-key mechanism where the service key can only be extracted when the system is in its normal armed state, ensuring facilities are never inadvertently left unprotected.

NFPA 2001 Trapped-Key Security & Safe Maintenance Isolation

The primary safety advantage of the Maple Armor FW2733 Addressable Disconnect Switch is its strict compliance with NFPA 2001 physical key safety mandates.

During routine fire alarm testing, air duct maintenance, or detector sensitivity calibration, accidental agent discharges can cause massive financial losses and life-safety hazards. Turning the key on the Maple Armor FW2733 Addressable Disconnect Switch safely disables the releasing circuit output while reporting a distinct supervisory trouble condition to the central FW2107 panel.

To eliminate human error, the physical key is physically trapped inside the switch cylinder while in the bypassed position. Technicians cannot extract the key until the switch is rotated back into the normal armed mode, ensuring building protection is immediately reinstated upon conclusion of maintenance tasks.

• Fail-Safe Key Retention: Key cannot be removed while the suppression system is bypassed, preventing forgotten disconnections.
• Brushed Stainless Steel Plate: Rugged, scratch-resistant metal faceplate provides clean aesthetics and long-term durability.
• Distinct Yellow Supervisory LED: Provides instant visual indication when the system is isolated from the central panel.
• Digital SLC Communication: Transmits supervisory trouble signals directly across the loop without needing auxiliary monitor modules.

Frequently Asked Questions (FAQ)

Q1: What is the primary function of the Maple Armor FW2733 Addressable Disconnect Switch?
A: The FW2733 is a key-operated safety switch used to temporarily disable and isolate clean agent suppression releasing circuits during testing, maintenance, or room servicing without putting the entire fire alarm panel out of commission.

Q2: Why can the key only be removed in the normal position?
A: In compliance with NFPA 2001 clean agent safety requirements, the key is trapped in the switch while in the “Disconnect” position to guarantee technicians physically re-enable and arm the suppression system before taking the key away.

Q3: How does the fire alarm panel respond when the switch is set to Disconnect?
A: The Maple Armor FW2107 control panel immediately registers a dedicated “Supervisory Trouble” event, alerting monitoring personnel that the suppression zone is manually bypassed, and illuminates the front yellow LED on the switch.

Q4: How many addresses does this disconnect switch consume on the SLC loop?
A: It occupies only one logical address on the Maple Armor Signaling Line Circuit (SLC) loop, supporting up to 252 total points per circuit.

Q5: What electrical backboxes are compatible with the FW2733 switch?
A: It mounts semi-flush onto standard North American single-gang electrical junction boxes or surface mounts using a standard single-gang metallic surface box.

Q6: Which fire alarm control panels are compatible with this disconnect switch?
A: The FW2733 is specifically designed for Maple Armor Series 2 control panels with agent releasing functionality, particularly the FW2107 dual-hazard releasing panel.
