RCI 4304-09 32D – Frequently Asked Questions

1) What does fail-safe mean on the RCI 4304 electric strike, and when should I use it instead of fail-secure?
The 4304 is a fail-safe strike: energize it to keep the door locked, and when power drops the keeper releases so the door can be pushed open from the outside. Use it on egress paths and stairwell or corridor doors where the authority having jurisdiction wants the opening to free up on a power loss. If you need the door to stay locked when power fails, a fail-secure strike is the right choice instead. Note the 4304 is not fire rated, so it is not for a labeled fire door assembly.
2) Will the RCI 4304 work with my cylindrical lockset or mortise lock?
Yes. The enlarged latch cavity takes cylindrical locks, narrowline aluminum locks, centerline mortise locks including the 3-piece anti-friction type, and mortise exit devices. What matters is the latch projection: the 4304 is built for a 3/4 inch projection latch. A deadlatch throwing more or less than that is the usual reason a strike like this will not hold alignment.
3) What frame prep depth does the RCI 4304 electric strike need?
Plan on a 1-1/2 inch cut-out depth in the frame, which clears most aluminum and wood frame profiles. The faceplate is the 4-7/8 inch round corner style, so the frame face has to accept that plate length. Door thickness is flexible, 1-3/8 inch through 2-3/8 inch.
4) What voltage do I order the RCI 4304 in, and do I have to watch wiring polarity?
Two voltages are offered, 12 VDC and 24 VDC, so pick to match your access control power supply. The coil is not polarity conscious, so crossed leads at the strike will not stop it working. AC or DC input is acceptable on fail locked models.
5) Is the RCI 4304 electric strike listed for access control and burglary resistance?
It carries UL 294 Listing for access control system units and UL 1034 Burglary-Resistant Listing, and it is certified to ANSI/BHMA A156.31 Grade 1, the highest grade in the electric strike standard. That combination is what most institutional and government specs call for. It is not fire rated and not ADA compliant.
6) Can I use the RCI 4304 on a labeled fire door?
No. The 4304 is not fire rated, so it does not belong in a labeled fire door assembly. A fail-safe strike unlocks on power loss anyway, which is the opposite of what a fire opening needs. For a rated opening, specify a fire-rated, fail-secure electric strike.
7) Will vibration or hammering on the door pop an RCI 4304 open?
The 4 Series uses an anti-vibration design specifically to stop the keeper being manipulated by vibration, which is the classic attack on a cheap strike. Paired with the UL 1034 burglary-resistant listing, that is why these show up on retail, industrial and municipal openings.
8) Is the RCI 4304 suitable for an apartment or house door?
It is classed as a commercial device, and it is sized and listed for commercial access control work: office, school, healthcare, retail and government openings. On a residential door you rarely have the 1-1/2 inch frame cavity depth it needs, so it is the wrong tool for a typical house jamb.
9) Where do I get the wiring diagram and cutout template for the RCI 4304?
RCI publishes installation instructions for the 4 Series, and the full RCI product catalog covers the series specifications; both are available as PDFs alongside the product. Cut power before you open the frame, run the correct gauge for the coil current at 12 or 24 VDC, then test latch engagement and the access control release before you close it up.
