Frequently Asked Questions
- What does normally closed mean for this switch?
Normally closed means the circuit is closed when the magnet is in position, and opens when the door or window is opened. - Where is a wide-gap reed switch used?
Wide-gap switches are commonly used on doors or gates where alignment is less precise or larger gaps are present. - Can this be used with any alarm panel?
It is typically compatible with most alarm or access control inputs that support normally closed contacts within the specified limits.
