Failsafe NC Electric Lock Module Compact aluminum alloy electric lock for 12V or 24V DC systems with adjustable release delay. Key benefits Reliable failsafe operation: The lock is NC mode failsafe, so it unlocks when power is cut and locks when power is supplied, reducing the risk of being unable to exit during a power outage. Easy installation and wiring: Clear wire assignments minimize installation errors. Red wire to NC, black wire to GND. Yellow and white wires are not required and can be left unconnected. Flexible timing: Builtin adjustable time delay lets you set the release time to 0, 3, or 6 seconds to match the behavior required by different access control setups. Durable and compact construction: Made from aluminum alloy with a unique compact design for reliable longterm use and spacesaving installation, helping improve conversion rates for tight installations. Specifications and function Wiring: red to NC, black to GND. Yellow and white lines are unused and do not require connection. Working voltage: 12V or 24V DC selectable. Time delay options: 0 second, 3 seconds, 6 seconds. Mode: NC failsafe type. Locked when powered, unlocked when power is off. Material: aluminum alloy. Compact form factor suitable for limited space. Compatibility and performance Designed for use with standard 12V or 24V DC access control power supplies and control panels. Suited to systems that require failsafe locking behavior and a short adjustable release delay. Compact size allows mounting in confined spaces while maintaining mechanical durability. Practical applications Access control doors: Integrate into office entry systems or secure rooms that require failsafe unlocking during power loss. Cabinets and server racks: Secure enclosures where controlled timed release is needed for maintenance or emergency access. Gates and barriers: Use with lowvoltage gate controllers to provide locked control when powered and automatic release if power is interrupted. What to expect Straightforward wiring and configuration. Stable failsafe locking performance compatible with common DC access systems. Durable aluminum alloy housing and compact footprint for flexible installation locations. Note wiring carefully before power up: connect red to NC and black to GND; yellow and white are not used.
