Installer and Estimator Checklist
- Mechanical preparation: Verify full-mortise hinge template, leaf width, length, thickness, knuckle style, corner radius, screw locations and door/frame reinforcement. Verify load class and any required listing using the exact SKU.
- Electrical routing: Confirm the factory lead and wire gauges, number of circuits, operating current, voltage drop, and available space for field terminations. Route conductors to protect them during full door swing.
- Compatibility: Identify the electric lockset, exit device, transfer switch or door-monitoring accessories connected through the hinge. Match their terminal requirements to the conductor arrangement; do not substitute a standard-weight or mixed-gauge model by wire count alone.
- Testing: Check hinge alignment, free door movement, wire continuity, insulation condition and device operation with the door in open and closed positions.
Package scope: The selected electrified hinge is supplied as its factory assembly. Locks, access controller, external power supply, wiring beyond the supplied leads and installation labor are not included unless separately specified.
Project Specification and Installer Checkpoints
For the 4-1/2 x 4 6-wire electrified transfer hinge, confirm both the mechanical hinge specification and the electrical circuit layout before selecting a finish. A power-transfer hinge is not interchangeable with a standard butt hinge merely because the leaf dimensions match.
Electrical Design
- Factory conductor configuration: 2 × 18 AWG power conductors + 4 × 28 AWG signal/control conductors. Confirm the wiring arrangement of the exact selected SKU against the current product sheet.
- Connected hardware: Identify the electric lock, latch-retraction hardware, door-position switch or monitoring contacts that the cable serves, and map each conductor to a circuit before installation. Reserve conductor capacity for required power and signals.
- Power sizing: Check total running and inrush current, voltage at the device under load, allowable conductor ampacity and maximum cable length using the electrical device and hinge manufacturers' specifications. Do not assume a particular amperage rating from conductor count alone.
- Termination and movement: Plan protected cable routing through prepared door and frame raceways, proper strain relief and termination access. Verify continuity and insulation integrity with the door fully open and closed.
Mechanical Fit and Ordering Requirements
- Hinge template: Verify leaf height and width, hinge thickness, five-knuckle pattern, screw-hole locations, corner style and door/frame mortise; compare the selected part number to the architectural hardware schedule.
- Door construction: Confirm door weight, hinge quantity, opening frequency, intended fire-door listing and any applicable frame reinforcement or manufacturer restrictions. Do not substitute a different hinge load class solely based on appearance.
- Series distinction: The WH-coded configuration may have a different electrical harness and/or hinge specification from the W-coded family. Check both before substitution.
