The primary advantage of the Maple Armor FW901W Notification Appliance Base is its two-piece plug-in installation method.
Once building finishes are complete, technicians align the appliance head and rotate it clockwise until the Maple Armor FW901W Notification Appliance Base locks firmly into place. The integrated copper terminal blades establish immediate, vibration-resistant electrical continuity across the system.
Q1: What notification appliances can be mounted onto the Maple Armor FW901W base?
A: The FW901W is designed for Maple Armor Series 2 notification appliances, including the FW2961 horn strobe, FW2971 audible horn, and FW2981 visual strobe.
Q2: What is the purpose of installing a separate base instead of a one-piece appliance?
A: A separate base allows full wiring rough-in and continuity testing during early construction phases, preventing delicate optical and acoustic components from being damaged by drywall dust or paint.
Q3: How does the appliance head attach to the FW901W base?
A: The appliance head mates via a clockwise twist-lock action, securely latching onto the internal terminal contacts without extra fastening tools.
Q4: What size electrical backboxes are compatible with this base?
A: It mounts directly onto standard 2×4 inch (single gang), 4×4 inch (double gang / 4″ square), and 4-inch octagonal electrical backboxes.
Q5: What wire gauge can be connected to the base terminals?
A: The screw terminal blocks accommodate solid or stranded copper wire from 18 AWG to 12 AWG (0.82 mm² to 3.31 mm²).
Q6: What certifications does the FW901W base hold?
A: It is fully listed and certified under UL and ULC standards as an approved fire protective signaling accessory.
