Door Hardware: ID-Card Lock Systems Require More Maintenance
By Thomas A. Westerkamp - May 2010 - Doors & Hardware
While new generation ID-card lock systems are highly reliable, they have many more components than, for example, mechanical mortise locks, which provide years of service and many thousands of cycles with only minimum inspection and lubrication.
This low-maintenance feature also is applicable to mechanical parts in an electronic lock. But in addition to the lock mechanism itself, electronic locks require a power source — either batteries or a wired connection to the power-distribution system — cameras, and alarms. They also require computer hardware and software for applications and database storage, as well as card printers and laminators.
As a result, along with more versatility comes much more equipment for departments to manage. Technicians must change or recharge lock batteries regularly, and they must inspect power-distribution components for wired systems, clean contacts in fused switches, and perform infrared testing to detect wiring hot spots.
Back-up components, such as generators, need regular cycling, oil changes, and safety-device checks to ensure they are ready for instant transition if power fails. Occupants also need smooth-operating door hardware to ensure efficient egress from the facility, especially during outages.
