SDC 45-4SU – Frequently Asked Questions

1) Will an SDC 45 Series electric strike work with my cylindrical lockset, or do I need a mortise strike?
The SDC 45 Series is a centerline latch entry strike built for cylindrical locksets and for mortise locksets without a deadbolt. If the mortise lock on your opening has a deadbolt, this is the wrong strike, because the strike only releases the latchbolt and a thrown deadbolt would still hold the door shut. For a mortise lock with a deadbolt you want a strike built for that prep, such as the Securitron MUNL mortise unlatch strike or the Von Duprin 6210 for mortise locks.
2) My lockset has a 3/4 inch latchbolt throw. Will the SDC 45 strike still accept it?
The 45 Series takes a 5/8 inch throw latchbolt, and it will take up to a 3/4 inch throw as long as you have a 1/8 inch door gap. So a 3/4 inch latch works only if that gap is there. Tight up against the stop with no gap, the keeper will not clear the longer latch and you should be using a strike cut for a 3/4 inch throw, like the HES Folger Adam 310-1(X) body, which covers 1/2, 5/8 and 3/4 inch throw latchbolts.
3) Does the SDC 45 Series electric strike fit a standard ANSI hollow metal frame prep?
It ships with a 4-7/8 inch square corner faceplate for hollow metal, which is the standard commercial ANSI strike prep, and the description covers both metal and wood frames. The faceplate is interchangeable and mounting tabs are included, and the body allows horizontal alignment adjustment so you can line the keeper up with the latch after the frame is prepped. For an aluminum jamb this is not the strike; an Adams Rite 7100 or 7160, both with a 1-1/4 x 4-7/8 inch faceplate, is built for aluminum.
4) Do I have to order the SDC 45 strike handed for a left or right hand door?
No handing to specify. The 45 Series is a non-handed design, so one part covers left and right hand openings. That is useful if you are stocking spares for a building with doors swinging both ways, since one strike on the shelf fits any of them.
5) What voltage does the SDC 45 electric strike run on, and can it run off my existing 24V access control power supply?
12 or 24 VDC, field selectable on the strike itself, so it drops onto either a 12V or a 24V supply without ordering a different part. It also carries voltage and current spike protection. If your panel or supply is AC rather than DC, this is not the strike for it; the Trine 001 series runs 8-16VAC and the Trine 2001 runs 16-24VAC/DC.
6) Can I use an SDC 45 strike with a rim exit device or a pair of doors with vertical rods?
No. The 45 Series is a centerline latch entry strike for cylindrical and mortise locksets, not for exit device hardware. A rim panic latch needs a rim exit strike such as the Hager 2945, which is fire rated with a latchbolt monitor. For surface vertical rods on a pair, the HES Folger Adam 310-4-2 is the complete strike pac built for that, and the Rockwood double door strike with a 3/4 keeper covers the pair application.
7) What fire rated electric strike alternatives are there to the SDC 45F?
The SDC 45 is offered as the 45 and the fire rated 45F, which carries UL 10C. Fire rated peers include the Camden CX-ED1410 and CX-ED1420 universal Grade 1 ANSI fire-rated strikes, the Camden CX-ED1689L-4 fire rated universal low profile supplied with 4 faceplates, and the Von Duprin 4211, a Grade 1 heavy duty fire rated strike for cylindrical locks at 12/24 VDC field-selectable.
8) What is the closest equivalent to the SDC 45 electric strike for a cylindrical lockset in a hollow metal frame?
The Von Duprin 4211 is the nearest peer for that opening. It is an electric strike for cylindrical locks with 12/24 VDC field-selectable operation and Grade 1 rating, which lines up with the SDC 45 running 12/24 VDC and meeting ANSI/BHMA A156.31 Grade 1. The Hager 2930 is a second route, a fire rated Grade 1 strike for cylindrical and mortise locks with 12/24 VDC dual voltage. Both cover the same dual-voltage cylindrical duty the SDC 45 is built for.
9) The frame is aluminum, not hollow metal. What electric strike should be used instead of the SDC 45?
The SDC 45 uses a 4-7/8 inch faceplate for hollow metal and wood frames. For a narrow aluminum jamb, the Adams Rite 7100 is built for aluminum jambs with a flat 1-1/4 inch by 4-7/8 inch faceplate, and the Adams Rite 7160 is also an aluminum jamb strike with a 1-1/4 inch by 4-7/8 inch faceplate. Adams Rite also makes the 7170 for hollow metal and wood jambs if the job includes a mix of frame types.
10) The frame cannot be cut for the SDC 45. What electric strike goes in without new prep?
The SDC 45 is a compact low profile strike with an interchangeable faceplate and mounting tabs, but it still needs a jamb cavity. Where cutting the frame is off the table, the Locknetics NC450 is a no cut electric strike. If the frame is already prepped to ANSI, the Dortronics 3300 Series ships with a strike plate for ANSI prep at 4-7/8 by 1-1/4 inches, which matches the SDC 45 faceplate width.
11) The SDC 45 is going on an exterior gate. Is that the right choice?
The SDC 45 is a commercial strike built for metal and wood frames, with stainless steel parts and a die cast body. For a gate in the weather, the Camden CX-ED1959 Series is an outdoor rated electric gate strike, which is the purpose-built answer for that application.
12) Does the SDC 45 switch between fail safe and fail secure like the Hager strikes?
The SDC 45 has field selectable operation and field selectable 12/24 VDC. The Hager 2925 and the Hager 2928 are both described as field reversible fail safe or fail secure, as is the Hager 2930. By contrast the Von Duprin 6210 is fail-secure at 24 VDC, and the RCI 15BS is fail-secure operation, so those two are fixed rather than switchable in the field.
13) What are the SDC 45 Series device options, and which one do I need to monitor the door at my access control panel?
Three choices when you order: no device option, K for keeper open status, or RMB for a buzzer. Pick K if you want the panel to see whether the keeper is standing open, which is how you confirm a release actually happened rather than trusting the relay fired. The RMB buzzer gives an audible cue at the door on release, common on a delivery or tenant entry where someone needs to hear the buzz and pull. The switch device is SPDT, and latch status monitoring and keeper deadlocked status are part of the strike.
14) Is the SDC 45 electric strike strong enough for a high traffic entrance that gets abused?
1,500 lbs holding force, 70 ft-lbs dynamic strength, and 250,000 endurance cycles, with all stainless steel parts in a die cast body. It also meets ANSI/BHMA A156.31 Grade 1 and is UL 1034 listed for burglary-resistant electric locking mechanisms. That covers a main entry, a school corridor, or a healthcare access point taking constant use.
15) I have very little room in the jamb. Will an SDC 45 strike fit where a bigger strike won't?
The 45 Series is built low profile and compact with an internally mounted solenoid and fewer moving parts, specifically for jambs where space is tight. Pigtail connectors come off the body for the wiring. If the jamb still will not take a cut, look at the Locknetics NC450, a no-cut electric strike, or the Camden CX-ED1689L-4 low profile unit that ships with four faceplates.
16) What is the closest alternative to the SDC 45 electric strike from another brand?
For a cylindrical lock on a hollow metal frame, the Von Duprin 4211 is the nearest match: Grade 1, heavy duty, fire rated, with field-selectable 12/24 VDC like the SDC. The Hager 2930 is another Grade 1 fire rated strike for cylindrical and mortise locks at 12/24 VDC dual voltage, and it adds field reversible fail safe or fail secure operation. The Adams Rite 7240 is a fire rated strike specifically for cylindrical locksets with a 5/8 inch latchbolt projection, matching what the SDC 45 accepts.
17) What is a simpler electric strike than the SDC 45 for a light duty interior door?
The SDC 45 is a commercial strike rated for 250,000 endurance cycles with 1,500 lbs holding force. Where that duty level is more than the opening calls for, the Trine 001 Series is a fail-secure light commercial strike with a 5-7/8 inch by 1-1/4 inch faceplate, and the RCI 15BS is an economy strike for special offset latch entry with fail-secure operation. Both are fail-secure only, while the SDC 45 offers field selectable operation.
18) The SDC 45 needs to monitor the door. Which other electric strikes offer monitoring?
The SDC 45 carries an SPDT switch device with latch status monitoring and keeper deadlocked status, and the K option adds keeper open status. Comparable monitored strikes include the Dortronics 3300 Series, which has a latch bolt sensing switch, 12/24VDC operation, and a strike plate for ANSI prep at 4-7/8 by 1-1/4 inches, and the Camden CX-ED1799L-8, a fire rated dual monitor Grade 1 strike supplied with 8 faceplates.
19) Which heavy duty electric strikes compare with the SDC 45 for a high traffic opening?
The SDC 45 is rated for 250,000 endurance cycles with 1,500 lbs holding force and 70 ft-lbs dynamic strength. Peers carrying a heavy duty rating include the Alarm Controls AES-100, a Grade 1 heavy duty strike, the Locknetics MDS100 and MS100 heavy duty strikes, and the Von Duprin 4211 and 6400, both Grade 1 heavy duty.
20) Are HES 1500 and 1600 accessories usable with an SDC 45 electric strike?
No. The HES 1500 and HES 1600 offerings are electric strike accessories for the HES 1500 Series and 1600 Series respectively, both Grade 1 and fire rated, and they belong to those HES strike bodies. The SDC 45 comes with its own interchangeable faceplate and mounting tabs for its 4-7/8 inch prep.
21) What finishes does the SDC 45 electric strike come in, so I can match the other hardware in the building?
Three finishes: 606 dull brass, 613 oil rubbed bronze, and 630 satin stainless steel. All three are available fire rated or non-rated, and with any of the device options. 630 is the usual pick on commercial hollow metal openings where the rest of the hardware is satin stainless.
