Buying Guide: Key Considerations for Electric Latch Retraction Mortise and Rim Locks
Choosing the right electric latch retraction device involves balancing door type, installation conditions, and security requirements. Consider these perspectives to make an informed decision.
- Door type and preparation: Mortise devices require a compatible mortise cavity and 1-1/8″ backset. Rim devices mount on the door edge without a mortise cavity, which can simplify retrofits but may affect aesthetics and security profile.
- Backset and hand preference: Most listed mortise models use a 1-1/8″ backset and offer reversible or non-reversible configurations. Confirm door swing (left/right) and hand to ensure proper operation.
- Electric requirements: Check voltage and power supply. Common options include 12VDC or 24VDC; ensure the building’s control system or power supply matches the device spec.
- Finish and compatibility: Choose finishes that match or complement surrounding hardware. Adams Rite devices typically offer multiple finishes to fit architectural style.
- Security features: Look for integrated checks such as bolt interlocks (e.g., star wheel), latch protection, and compatibility with request-to-exit (REX) systems or access control panels.
- Installation and maintenance: Mortise devices require precise alignment and frame prep. Rim devices may be easier to retrofit but require proper strike alignment with the keeper.
- Compliance and warranty: Ensure devices meet relevant building codes and ANSI standards. Verify warranty terms and service accessibility for longer-term reliability.
- Power failure behavior: Determine whether the lock should be fail-secure (door remains locked when power is off) or fail-safe (door unlocks when power is off). This influences safety and egress design.
- Lifecycle and traffic: For high-traffic entries, select devices rated for frequent operation and easy replacement of components like latches or strikes without extensive downtime.
In selecting between mortise and rim configurations, prioritize door construction, frame compatibility, and security requirements. Adams Rite models offer a widely supported ecosystem with consistent performance, while ensuring ease of integration with modern access-control systems.
