ROFU 9303 US28 – Frequently Asked Questions

1) What does the ROFU 9303 push button actually do in a door release circuit?
The 9303 is a blue DPDT request-to-exit push button from ROFU's 9300 Series, rated 0.5A at 250VAC. DPDT means two independent sets of changeover contacts, so one press can break power to a mag lock or strike while the second pole signals an alarm panel or shunts a door contact. The 9303 version includes the electronic time delay option, so the door stays unlocked for an adjustable 1 to 30 seconds after the press instead of relocking the instant you let go.
2) Do I need a separate timer relay to hold an electric strike open with this ROFU button?
No. The time delay is built into the 9303, with relocking adjustable from 1 to 30 seconds, so you are not adding an external timer relay in the enclosure for a simple momentary-to-timed release. If you want straight momentary action with no hold time, that is the plain 9300 Series button without the time delay option rather than this one.
3) Is the ROFU 9303 tamper resistant enough for a public corridor or a school exit?
The cover plate is 1/4 inch thick aluminum and ships with two snake eyes security screws plus the matching wrench, so it cannot be opened with a standard screwdriver or Torx bit. That combination is the reason these get specified in public-side locations. It is a commercial-duty device, not a residential switch.
4) Is the ROFU 9300 push button UL listed?
The 9300 Series push buttons are UL Recognized Components. That is a component recognition, not a standalone end-product listing, so the access control panel or power supply it wires into carries its own listing for the overall system.
5) What finish does US28 mean on the ROFU 9303, and what is the other choice?
US28 is clear anodized aluminum, which is the finish on the 9303 US28. ROFU's other 9300 Series finish is US40, dark anodized bronze. If you are matching existing dark bronze frames or other bronze-anodized plates in the building, order US40 instead of US28.
6) Can I get an LED or a different button color instead of blue on the ROFU 9300 series?
Blue is the standard button color on the 9300 REX switches. An LED indicator for on/off position is an available option, and alternate button colors can be specified: red for momentary, or red, orange and green for maintained. Those are order-time selections, so call them out on the purchase order rather than expecting to swap them in the field.
7) How does the ROFU 9300 push button compare with a Detex PB-2100 push button control?
Both are commercial push button controls for door release. The ROFU 9300 is a DPDT blue button behind a 1/4 inch aluminum plate with snake eyes security screws, and the 9303 adds the 1 to 30 second electronic time delay. The Detex PB-2100 Series push button control we carry comes with a shroud and Form C terminals, so the shroud is the difference if your concern is someone bumping the button in a tight corridor. Choose the ROFU 9303 where you want built-in timed relock without an external timer.
8) What is an alternative to the ROFU 9303 push button if the opening needs a shrouded button with Form C terminals?
The ROFU 9303 is a blue DPDT push button on a tamper-resistant 1/4 inch thick aluminum cover plate, supplied with two snake eyes security screws and a wrench, and its time delay option gives an adjustable relocking time of 1 to 30 seconds. If the request exit point instead calls for a shrouded button, the Detex PB-2100 series push button control is offered with a shroud and Form C terminals. The shroud guards against accidental actuation, which matters in corridors and equipment rooms where the button sits at hand height; the ROFU approach to tamper resistance is the thick aluminum plate and security screws rather than a shroud.
9) Does the Detex PB-2100 push button control include the time delay function that the ROFU 9303 offers?
The time delay is a ROFU 9300 series option: an electronic time delay with adjustable relocking time of 1 to 30 seconds, which is what the 9965 designation on the 9303 refers to. The Detex PB-2100 series push button control is described as a push button control with shroud and Form C terminals, so if you need the delay built into the button itself rather than handled by a separate timer or the access control panel, the ROFU 9303 with the time delay option is the one to specify.
