Frequently Asked Questions
Q: What voltages does this electric bolt lock support?
A: This concealed electric bolt lock supports both DC 12V and DC 24V, making it compatible with a wide range of access control power supplies and systems.
Q: Is this lock fail-safe or fail-secure?
A: This lock operates in fail-secure mode — it locks when power is off and unlocks when power is applied. This means the door remains secured during a power outage, which is ideal for security-sensitive applications.
Q: What type of installation does this electric bolt lock require?
A: The LY-03T uses a drilling (concealed/embedded) installation method. It is designed to be hidden within the door or frame for a clean, discreet look. Standard drilling tools are required for mounting.
Q: Can I use this lock continuously or at high frequency?
A: No. This electromagnetic bolt lock is intended for instantaneous use only, with a maximum recommended power-on duration of 5 seconds per cycle. Continuous or high-frequency operation may cause damage to the lock and will void functionality.
