Frequently Asked Questions
Q: What is the difference between the Square (Z30LS) and Rectangle (Z53LS) exit button versions?
A: Both versions function identically as push-to-exit release buttons with NO/NC/COM contacts and a DC 12V input. The main difference is physical form factor: the Square version measures 5.3 × 2.6 × 5.3 cm, while the Rectangle version measures 3 × 2.3 × 8 cm. Choose based on your wall plate, gang box, or aesthetic preference. Be sure to specify your choice in the order notes.
Q: Is this exit button compatible with my existing access control system?
A: Yes — this switch supports NO (Normally Open), NC (Normally Closed), and COM (Common) output contacts, making it compatible with the vast majority of access control panels and electric lock systems on the market. It operates at DC 12V with a contact rating of 3A at 36V DC max, which covers most standard door controller configurations.
Q: Can this exit button be installed outdoors?
A: This button is rated for operating temperatures of -20°C to +55°C and up to 95% relative humidity, giving it reasonable tolerance for covered outdoor or semi-outdoor installations such as covered entryways or building lobbies. For fully exposed outdoor installations with direct rain exposure, additional weatherproofing housing is recommended.
Q: Does the backlight require a separate power connection?
A: The backlight is powered through the same DC 12V input used by the button switch itself, so no separate wiring is needed. The illuminated button makes it easy to locate in low-light conditions without additional electrical work.
