Frequently Asked Questions
- Does this button provide Normally Closed output as well?
No. NEPMNCS is specified as NO/COM only. If you need Normally Closed as well, choose a model that lists NO/NC/COM in the specifications. - Can this be surface mounted on a mullion?
Yes. It can be surface mounted using the optional NEMSMB mullion mounting box (sold separately). - What is a common wiring mistake to avoid?
Avoid wiring the button as if it has a Normally Closed contact. This model is NO/COM, so confirm your controller input expects a Normally Open request-to-exit signal.
Additional Information
- If your access controller is configured for Normally Closed monitoring, select a model in the range that provides NO/NC/COM to match the input type.
- For narrow aluminium frames, mullion format plates reduce the need for oversized cut-outs while still keeping standard 83 mm fixing centres.
- Where visual confirmation is needed, consider an LED variant (for example, a model in the range that lists an LED indicator) rather than adding external indicators.
