ROFU 9149B – Frequently Asked Questions

1) Will the ROFU 9149B let me run a 12 VDC strike off my existing 24 volt access control power supply?
That is exactly what the 9149B inline controller is built for. It takes an input of 12 to 24 VAC or VDC and drops it to a regulated 12 VDC output at 1 amp, so a 12 VDC strike or maglock can be driven from a 24 volt supply or from an AC transformer. Check that the lock's inrush and holding current stay inside the 1 amp output.
2) Does the ROFU 9149B accept AC input, or do I need a DC supply?
Either works. The input range is 12 to 24 VAC or VDC, so it can be fed straight from a low voltage AC transformer as well as from a DC supply, and it still puts out 12 VDC.
3) How much current can the ROFU 9149B supply to a lock?
Output is 12 VDC at 1 amp. That covers most single electric strikes and smaller electromagnetic locks. If you are powering several openings off one device, or a maglock drawing near or above an amp, you need a larger dedicated supply rather than an inline converter.
4) What is the buzzer on the ROFU 9149B for?
The 9149B is the buzzer version of the inline controller. It sounds when the output is energized, giving an audible cue at the door that the strike has been released, which is what people are listening for on an intercom or entry buzz-in setup. There is also a red LED indicator for a visual confirmation at the device.
5) Do I still need a separate power supply if I use the ROFU 9149B?
Yes. The 9149B is a converter, not a power source. It needs an existing 12 to 24 VAC or VDC feed in front of it, and it conditions that down to 12 VDC at 1 amp for the lock. Plan the transformer or power supply, the converter, and the locking device as three separate line items.
6) Is the ROFU 9149B rated for commercial door hardware use?
It is classified as a commercial product, and it sits in the electronic access control accessory line rather than a residential doorbell converter. Typical use is inline between an access control or intercom power feed and a 12 VDC locking device.
