Analog and digital timers control exactly how long an access-control device stays energized: programmable timer modules that hold a door strike or lock unlocked for a set duration after a valid credential, or run other security devices on a schedule, before automatically returning the system to its secured state. Precise timing here is what keeps a door both usable and secure.
Match the timer to the power supply and lock hardware it controls - timer modules are typically add-on boards for a specific power-supply platform, and their timing range and output rating need to fit the lock or device downstream. Set unlock durations deliberately: too short frustrates legitimate access, too long undermines the security the access-control system is there to provide. For sites with varying access needs by door or by time of day, confirm the timer supports the scheduling flexibility the security policy actually requires. COLAMCO supplies timer modules alongside the access-control power supplies business, government, and education security programs install.
