Installation & Operation

  1. Verify electrical requirements match available power supply and confirm current capacity before proceeding with installation.
  2. Disconnect power supply before beginning installation. Follow all applicable electrical codes and safety procedures.
  3. Mount the strike in the door frame ensuring proper alignment with the latch and adequate clearance for the 1-1/2" cut-out depth requirement.
  4. Route and connect wiring according to manufacturer wiring diagrams. Use appropriate wire gauge and connectors for the application, taking advantage of the non-polarity-conscious coil design.
  5. Configure fail-secure operation settings per application security requirements and test anti-vibration functionality.
  6. Restore power and test all functions including normal latch operation, strike release, and integration with connected access control systems.
  7. Complete final inspection and document settings. Refer to manufacturer documentation for complete wiring diagrams, programming instructions, and troubleshooting.

RCI 4108-08 32D – Frequently Asked Questions

1) Will the RCI 4108 electric strike work on a 1-3/4 inch door?
Yes. The 4108 covers door thicknesses from 1-3/8 inch to 2-3/8 inch, so 1-3/4 inch, the standard commercial thickness, sits mid-range. The strike itself mounts in the frame, not the door, so what you also need to confirm is frame depth: the 4108 needs a 1-1/2 inch cut-out depth, which suits most aluminum and wood frame profiles.
2) Does the RCI 4108 stay locked or unlocked when the power goes out?
Locked. The 4108 is fail-secure, so pulling power leaves the strike secured and the door has to be opened by key or by mechanical egress from the inside. That is the right choice on a stairwell, a tenant suite, or an exterior opening where you do not want the building open during an outage. If your code official requires the opening to release on power loss, this is the wrong unit and you need a fail-safe strike instead.
3) What kind of locks does the RCI 4108 electric strike accept?
Cylindrical locks and mortise locks, plus mortise exit devices. The latch cavity is enlarged, so it takes cylindrical latches, narrowline aluminum locks, and centerline mortise locks including the 3-piece anti-friction type. The one number that decides it is latch projection: the 4108 is built for a 3/4 inch projection latch. Measure what is throwing out of your existing lock before you order.
4) What voltage do I order the RCI 4108 electric strike in?
Three coil options: 11-16 VAC, 12 VAC/DC, and 24 VAC/DC. Pick from the power supply already feeding the opening, since 12 and 24 volt are the two common access control rails. The coil on fail-locked models is non-polarity-conscious and accepts AC or DC input, so you do not have to chase a crossed wire at the strike. The 11-16 VAC option is the one to take if you are running the strike off an AC transformer for buzzer-style release.
5) Can I put the RCI 4108 on a fire rated door?
No. The 4108 carries no fire rating, and a fire door opening needs a fail-secure strike that is listed for fire door assemblies. For a rated opening, specify a fire rated electric strike. The 4108 is for non-rated commercial openings.
6) Is the RCI 4108 electric strike UL listed for access control?
UL 294 Listed for access control system units, and additionally UL 1034 Burglary-Resistant Listed. It is also certified to ANSI/BHMA A156.31 Grade 1, the top grade in the electric strike standard. That combination is what a spec on a commercial or institutional job usually calls for when the strike is part of a card access system and the opening is on the building perimeter.
7) Is the 7-15/16 inch faceplate on the RCI 4108 a flat or round corner plate?
Round corner. The 4108 ships with a 7-15/16 inch round corner faceplate, which is the profile that drops into an aluminum frame jamb prepped with radiused corners. If the existing cut-out in your frame is square-cornered, a round corner plate will leave gaps at the corners and you want a square corner faceplate instead.
8) Will vibration or hammering pop an RCI 4108 electric strike open?
The 4108 uses an anti-vibration design specifically to stop the keeper being manipulated open by vibration, which is the classic attack on a cheap strike in an aluminum storefront frame. Paired with the UL 1034 burglary-resistant listing, it is the strike to use where the opening is exposed to the street.
9) Can I use the RCI 4108 to standardize the electric strikes across a whole building?
Within limits, and the limits are worth knowing before you buy a pallet. The 4108 covers a lot of ground: cylindrical and mortise locks, mortise exit devices, doors 1-3/8 to 2-3/8 inches, and three voltages. Two things break the standardization. First, every opening it goes on has to be non-rated, since the 4108 has no fire rating and your stair and corridor doors probably do. Second, the latch has to project 3/4 inch and the frame has to take a 1-1/2 inch deep cut-out with a round corner prep. Survey the openings against those four points and the ones that pass can all take the same part number.
10) Does an RCI 4108 electric strike satisfy ADA requirements for an accessible opening?
The 4108 is not an ADA compliant device on its own. It releases the latch electrically but does nothing to open the door, so on an opening that has to be accessible you still need the door operator or the hardware that provides the accessible operation. Treat the strike as the release, not the accessibility solution.
11) Where do I get the wiring diagram and frame cut-out template for the RCI 4108?
RCI publishes installation instructions for the 4108 covering the frame prep and wiring, and the full RCI product catalog covers the 4 Series range. Pull the installation sheet before you cut the frame, since the 1-1/2 inch cut-out depth and the 7-15/16 inch faceplate prep have to be laid out from it rather than eyeballed against the old strike.
12) Is the RCI 4108 electric strike rated for commercial use or is it a residential part?
Commercial. The 4108 is a 4 Series strike built for commercial access control, and the Grade 1 certification to ANSI/BHMA A156.31 is the commercial-duty grade. It goes into office buildings, retail, healthcare, schools, and multi-tenant residential common area doors, not into a single family house.
