Frequently Asked Questions
Q: What is the difference between the 3-wire (SM603-3) and 5-wire (SM603-5) versions of this electric drop bolt lock?
A: The 3-wire version (SM603-3) provides basic locking and unlocking control via three wires, making it suitable for simpler access control setups. The 5-wire version (SM603-5) offers additional functionality — typically including door status feedback signals — allowing integration with alarm panels, security monitoring systems, or more advanced controllers.
Q: Is this electric drop bolt lock suitable for outdoor use?
A: Yes. The Asia-Teco SM603 electric drop bolt door lock features a waterproof construction that protects internal components from rain, moisture, and humidity, making it well-suited for outdoor gates, exterior doors, and covered outdoor entryways.
Q: How does the auto time delay function work on this electronic cylinder lock?
A: The built-in time delay feature keeps the door unlocked for a preset duration after receiving an access signal, then automatically re-engages the drop bolt to secure the door — eliminating the need to manually trigger relocking. This is especially useful in high-traffic access points.
Q: What power supply do I need for this DC12V electric drop bolt lock?
A: This lock requires a standard DC 12V power supply, which is the most common voltage used in access control systems. Most existing access control panels and standalone 12V adapters are compatible. Ensure your power supply has sufficient amperage for reliable operation.
