ACSI 1335-2 – Frequently Asked Questions

1) How does the ACSI 1335-2 door position sensor detect whether the door is open or closed?
It's a two-piece magnetic contact. The sensor body mounts in the frame and a separate magnet mounts in the door; when the door closes, the magnet comes into proximity with the frame-mounted sensor and the contacts change state. That's how the 1335 confirms door position back to an access control panel or alarm.
2) Does the ACSI 1335-2 give me both a normally open and a normally closed output?
Yes. The 1335-2 is SPDT with NO/NC contacts, so you have a single set of changeover contacts and can wire either polarity. That matters when your panel expects a closed loop on a secure door but your auxiliary device (a local alarm or a relay) needs the opposite state off the same sensor.
3) I need door position monitoring in a hazardous location. Can I use the ACSI 1335-2?
No, not the 1335-2. It's an electrical magnetic contact with SPDT switching. ACSI makes pneumatic models in the same door position sensor family specifically for hazardous locations, and that's what you want where an electrical contact isn't permitted.
4) What does ANSI mean on the ACSI 1335-2 door position sensor?
It refers to the ANSI-prep housing style, meaning the sensor is made to drop into an ANSI standard frame prep rather than requiring a separate surface-mount box. If your hollow metal frames were prepped to the ANSI pattern, that's the version to order.
5) Does the ACSI 1335-2 lock the door or just report its position?
Reports only. A door position sensor confirms whether the leaf is open or closed and sends that as a dry contact signal. It provides no securing function, so it's installed alongside an electric strike, maglock, or exit device, not in place of one.
6) Do I get the magnet with the ACSI 1335-2, or is that ordered separately?
The 1335 works as a matched pair: the magnetic sensor mounts in the frame and its companion magnet mounts in the door. Both halves are part of the door position sensor assembly, so plan the frame prep and the door prep together when you lay out the opening.
7) Is the ACSI 1335 door position sensor suitable for commercial openings, or is it a residential alarm contact?
Commercial. The 1335 is part of ACSI's 1300 Series access control line and is catalogued for commercial use, which is the relevant distinction for an institutional or multi-family buyer standardizing door monitoring across a facility rather than buying a residential alarm contact.
