SDC 45-4RV – Frequently Asked Questions

1) What latchbolt throw does the SDC 45 strike accept?
It takes a 9/16 inch throw latchbolt, or up to a 5/8 inch throw latchbolt where you have a 1/8 inch door gap. It's a centerline latch entry strike for cylindrical and mortise locksets without a deadbolt, so if the lock on the door throws a deadbolt into the frame this is the wrong strike for it.
2) Can I use one SDC 45 strike on both aluminum and wood frames?
The 45F radius corner faceplate versions are made for aluminum and wood applications. If your frame is hollow metal with a square ANSI cutout, look at a strike prepped for that instead, such as the Dortronics 3300 Series with its 4-7/8 x 1-1/4 inch ANSI prep plate or the Adams Rite 7170 for hollow metal and wood jambs.
3) What do the K and RMB options on the SDC 45 strike do, and do I need one?
Three device configurations are orderable: None, K for keeper open status, and RMB for a buzzer. Choose K when the access control panel needs to know the keeper is open or deadlocked, using the SPDT switch. RMB gives an audible buzz at the door when the strike is released, which is what people expect on an apartment or office entry with a phone or intercom release. If your panel doesn't monitor the door and nobody needs the audible cue, order None.
4) Is the Adams Rite 7100 a substitute for the SDC 45 electric strike?
Not on a fire door. The SDC 45 Series is UL 10C Positive Pressure certified and ANSI/BHMA A156.31 Grade 1. The Adams Rite 7100 Series carries no fire rating in its specifications, and the same is true of the Adams Rite 7160 and the 7170. Those are aluminum jamb strikes with a 1-1/4 inch by 4-7/8 inch flat faceplate, dimensionally close to the SDC 45 4R faceplate at 4-7/8 inch with radius corners, which is what makes them look interchangeable. If the opening is a fire door assembly, the Adams Rite fire-rated option is the 7240, a fire-rated strike for cylindrical locksets with 5/8 inch latchbolt projection - the same latchbolt throw the SDC 45 accepts.
5) The SDC 45 will not work with the rim exit device on my door - what fire-rated strike will?
The SDC 45 Series is a centerline latch entry strike for cylindrical and mortise locksets without deadbolt, so an exit device opening needs a different strike. For a rim exit device, the Hager 2945 is a fire rated rim exit strike with field selectable fail safe/fail secure and a latchbolt monitor - a monitoring feature comparable to the latch status output on the SDC 45. For surface vertical rod devices, the HES Folger Adam 310-4-2 is a complete Grade 1 electric strike pac, and for a pair of doors the Rockwood double door strike with 3/4 keeper is fire rated Grade 1 on the 310-1 platform.
6) What is the closest equivalent to the SDC 45F electric strike from another manufacturer?
The SDC 45 Series is a fire-rated Grade 1 strike for cylindrical and mortise locksets without deadbolt, running field selectable 12/24 VDC. The Hager 2930 is the nearest match in the same terms: it is a fire rated Grade 1 electric strike for cylindrical and mortise locks with 12/24VDC dual voltage. The Von Duprin 4211 is another Grade 1 fire rated strike for cylindrical locks with 12/24 VDC field-selectable operation, in a heavy duty build. Where they part company is function handling - the Hager 2930 is field reversible fail safe/fail secure, while the SDC 45 is specified for latch status and keeper deadlocked monitoring with an SPDT switch.
7) Which electric strike should I use on a mortise lock instead of the SDC 45?
The SDC 45 Series is specified for cylindrical and mortise locksets without deadbolt, so it already covers mortise openings. If you want a strike built specifically around a mortise lock, the Von Duprin 6210 is a heavy duty Grade 1 strike for mortise locks, UL 10C fire rated, running 24 VDC fail-secure, and the Securitron MUNL Series Mortise UnLatch is a fire rated Grade 1 mortise strike. The Von Duprin 6400 is a Grade 1 modular strike that covers either mortise or cylindrical locks, fail-secure, with a 3-hour UL 10C rating in satin stainless steel. Note the 6210 is single voltage 24 VDC where the SDC 45 is field selectable 12/24 VDC.
8) I need latchbolt monitoring on a 12/24VDC strike - what else does that besides the SDC 45?
The SDC 45 Series provides latch status and keeper deadlocked status monitoring through an SPDT switch device on field selectable 12/24 VDC, and can be ordered with the K keeper open status option or the RMB buzzer. The Dortronics 3300 Series is the direct alternative: an electric strike with a latch bolt sensing switch on 12/24VDC, with a strike plate for ANSI prep at 4-7/8 by 1-1/4 inch. The Hager 2945 also carries a latchbolt monitor and is fire rated, though it is a rim exit strike rather than a latch entry strike.
9) What fire-rated strike runs on AC power instead of the SDC 45 DC input?
The SDC 45 Series is a DC device, field selectable 12/24 VDC with voltage and current spike protection. If the transformer on the job is AC, the Trine 004 is a fire rated fail secure strike at 8-16VAC with a 6-1/4 inch by 1-3/8 inch faceplate and up to 5/8 inch throw, and the Trine 2001 is a fire rated fail secure strike at 16-24VAC/DC with a 5-7/8 inch by 1-1/4 inch faceplate and up to 5/8 inch throw. Both take the same 5/8 inch maximum latchbolt throw the SDC 45 accepts.
10) Is an electric strike rated tough enough for a busy commercial entrance?
The SDC 45 is built for that duty: 1,500 lbs holding force, 70 ft-lbs dynamic strength, and 250,000 endurance cycles, with stainless steel components in a die cast body. That's the commercial-grade end of the range. A light commercial opening with low traffic doesn't need it, and the Trine 001 Series is a light commercial fail-secure strike by comparison.
11) My jamb has very little depth. Will an electric strike fit?
The SDC 45 uses a compact low profile body with fewer moving parts, which is why it goes into aluminum jambs where depth is tight. If you can't cut the jamb at all, that's a different problem, and the Locknetics NC450 is a no-cut electric strike built for that case. For low profile with multiple faceplates in the box, the Camden CX-ED1689L-4 is fire rated and ships with 4 faceplates.
12) What's the closest alternative to an SDC 45F fire-rated strike if I need a different faceplate?
For the same job, a fire-rated strike taking a 5/8 inch latchbolt on a cylindrical lock, the Adams Rite 7240 is the direct counterpart. If you need dual monitoring rather than the single SPDT switch, the Camden CX-ED1799L-8 is a fire rated Grade 1 dual monitor strike shipping with 8 faceplates. For a mortise lock specifically, the Securitron MUNL mortise unlatch strike is fire rated Grade 1.
13) Can the SDC 45 strike signal the access control panel when the door is secure?
Yes. It provides latch status (LS) monitoring and keeper deadlocked status through an SPDT switch, so the panel can see both that the latch is in the keeper and that the keeper is deadlocked. Order the K device option if you also want keeper open status reported. That's the feedback an integrator needs for door-forced and door-held alarms.
14) Which Grade 1 heavy duty electric strikes compete with the SDC 45 for a high-traffic entrance?
The SDC 45 Series is rated to 250,000 endurance cycles with 1,500 lbs holding force and 70 ft-lbs dynamic strength, and holds ANSI/BHMA A156.31 Grade 1 with UL 1034 burglary-resistant listing. In the same Grade 1 heavy duty class, the Alarm Controls AES-100 is a Grade 1 heavy duty strike, the Von Duprin 4211 is heavy duty Grade 1 and fire rated for cylindrical locks at 12/24 VDC field-selectable, and the Von Duprin 6400 is a heavy duty Grade 1 modular strike covering mortise or cylindrical locks with a 3-hour UL 10C fail-secure rating. The Camden CX-ED1410 and CX-ED1420 are universal Grade 1 ANSI fire-rated strikes in the same tier.
