ROFU 2400 KIT – Frequently Asked Questions
1) Will the ROFU 2400 KIT electric strike work with a cylindrical lockset?
That's exactly what the 2400 KIT is built for. It's a universal electric strike designed for cylindrical locksets, and it handles a latch throw up to 5/8 inch with a 1/8 inch door gap. If your latchbolt projects more than 5/8 inch, or your door-to-frame gap is wider than 1/8 inch, the latch won't seat correctly in the keeper. Mortise locks and deadlatch-style exit devices are a different strike entirely.
2) What comes in the ROFU 2400 KIT, and what do I need to buy separately?
The kit ships with the strike body and two faceplates, so you have a choice of prep without a second order. Sold separately are the 2402 jig for jamb preparation and lip extensions in 1 inch and 2 inch lengths. Order a lip extension when the frame is set back from the door face and the standard lip won't reach the latch. The jig is worth having if you're prepping more than one opening.
3) What is the closest equivalent to the ROFU 2400 KIT electric strike if I need field selectable fail safe and fail secure operation?
The Adams Rite 7400A Series Ultraline electric strike body kit is the nearest peer on that point - it is a body kit with field selectable fail safe/fail secure operation, the same field-changeable behavior the ROFU 2400 KIT offers when it is reversed between fail safe and fail secure. The difference to weigh is what the strike is prepared to catch: the ROFU 2400 KIT is a universal, burglary-resistant strike designed for cylindrical locksets, with a 5/8 inch maximum latch throw and 1/8 inch door gap. Confirm the latch on the door against that throw before treating the two as interchangeable.
4) How much current does the ROFU 2400 strike draw, and will it run on PoE?
Current draw is 300 mA at 12 VDC or 150 mA at 24 VDC, and ROFU calls the 2400 PoE friendly. The 24 volt figure is the one that matters if you're powering through an access control board off a PoE budget, since 150 mA leaves headroom for the reader and controller on the same supply. Size your power supply for the full door count, not just this strike.
5) What is the difference between the ROFU 2400 KIT and the Adams Rite 7400A electric strike?
Both are field selectable between fail safe and fail secure operation. The split is what they mount to: the ROFU 2400 is a universal strike for cylindrical locksets with a 5/8 inch maximum latch throw, while the Adams Rite 7400A Ultraline is a strike body kit from the 7400 Series. The Adams Rite 7400A is listed as not fire rated. If your opening has a cylindrical lockset, the 2400 KIT is the direct fit.
6) My electric strike doesn't sit flush in the jamb. Does ROFU sell a spacer for the 2400?
For the 2400, the fix for a frame set back from the door face is a lip extension, offered in 1 inch and 2 inch lengths. Shim-style spacer plates are a Trine 4800 series item, not a ROFU part: the Trine 4800-SS is a 1/8 inch spacer plate and the 4850-SS a 1/4 inch spacer plate, and both are for Trine 4800 series strikes. Don't mix them into a 2400 install.
7) Can I use one electric strike model across a building with different door prep?
The 2400 KIT is the part built for that. One strike covers both 12 and 24 VDC, reverses in the field between fail safe and fail secure, and ships with two faceplates, so a property manager or facility buyer stocks a single SKU instead of four variations. The limits to check on each opening are the same two every time: a cylindrical lockset with no more than 5/8 inch of latch throw, and a door gap of 1/8 inch or less.
8) Can I use a Trine 4800-SS or 4850-SS spacer plate to shim a ROFU 2400 electric strike in the jamb?
No - those are series-specific parts, not universal shims. The Trine 4800-SS is a 1/8 inch spacer plate for 4800 Series electric strikes and the Trine 4850-SS is a 1/4 inch spacer plate for 4800 Series electric strikes; both are cut for the Trine strike body and faceplate footprint. The ROFU 2400 KIT ships with two faceplates and has its own dedicated accessories - a 2402 jig for jamb prep and 1 inch and 2 inch lip extensions. Order the ROFU accessories for a ROFU strike and the Trine plates for a Trine strike.
9) If I already stock Trine 4800 accessories, do I still need ROFU specific parts for a 2400 strike?
Yes. The Trine 4800-AK is an accessories kit for the 4800 Series, and the 4800-SS and 4850-SS spacer plates are likewise 4800 Series parts - none of them are keyed to the ROFU 2400 body. The 2400 KIT itself already includes two faceplates and is dual voltage, so a mixed-brand accessory shelf does not change what the strike needs out of the box; the only add-ons designed for it are the 2402 jig and the 1 inch and 2 inch lip extensions. For a facility standardizing on one strike, that is the practical argument for picking a single series rather than mixing bodies and accessory kits.
