The Kidde 1501-AQN5 is a floor-mounted electromagnetic door holder built for single-door fire safety applications. Multi-voltage operation (24 VAC/DC and 120 VAC) means it ties into whatever power is already available at the door - no transformer swaps, no extra runs. Fail-safe by design: power loss releases the door automatically, keeping the building code-compliant without a single moving part.
Built for the commercial installer
Conduit connects directly into the floor plate, and the floor plate plus housing form a weatherproof electrical junction box when installed with gaskets. No external J-boxes, no extra hardware. The shock-absorbing nylon swivel ball adjusts to any door angle, so alignment is forgiving on offset or angled door swings. UL and ULC listed. Aluminum-color baked polyester powder paint finish holds up in high-traffic commercial environments.
