Frequently Asked Questions
- Does this set hide the fixing screws and terminals?
Yes. Snap-on covers conceal the terminals and mounting screws for a clean finish. - Is this designed for screw terminal wiring?
Yes. The connection type is screw terminals and the terminals are angled away from the mounting surface to make wiring easier. - What is a common installation mistake to avoid?
Avoid misalignment between the reed part and magnet part - poor alignment can reduce effective operating gap and cause nuisance alarms.
Additional Information
- Concealed fixing contacts are commonly used where exposed screws and terminals are not desirable on visible frames.
- The included 3 mm packers are useful for correcting small frame-to-leaf height differences or improving magnet alignment.
- For timber openings with larger clearances, consider a wide-gap surface mount reed switch instead of increasing the installed gap.
