Frequently Asked Questions
Q: What is the difference between NO and NC contact modes on this exit button?
A: NO (Normally Open) means the circuit is open at rest and closes when the button is pressed — commonly used to trigger door unlocking. NC (Normally Closed) means the circuit is closed at rest and opens when pressed — used in certain alarm or fail-safe configurations. The COM terminal is the common shared connection. The LIHTNE K9 supports both modes, giving you full flexibility for your access control setup.
Q: Is this exit button compatible with magnetic locks and electric strike locks?
A: Yes. The K9 exit button is designed to work with standard access control systems, including magnetic locks (maglocks) and electric strike locks, as long as the system operates within the button's rated 3A @ 36VDC electrical specification. Always verify your lock controller's requirements before installation.
Q: Can this push switch be installed in a standard electrical wall box?
A: Absolutely. The 86 × 86 mm face plate conforms to standard single-gang wall box dimensions, making it straightforward to mount in most existing wall installations. The slim 25 mm depth keeps the profile low-profile and unobtrusive.
Q: Is the LIHTNE K9 suitable for outdoor use?
A: The K9 is rated for humidity up to 95% and temperatures from -10°C to +55°C, making it suitable for many indoor and sheltered outdoor applications. For fully exposed outdoor environments, consider adding a weatherproof enclosure to protect the unit from direct rain and the elements.
