Adams Rite 7240-340-630-00 – Frequently Asked Questions

1) Will the Adams Rite 7240 electric strike work with my cylindrical lockset?
Yes, the 7240 is built for cylindrical locksets, and the limit to check is latchbolt projection: it accepts latchbolts up to 5/8 inch (15.9 mm). If the lockset on the door throws a longer bolt, or if the opening uses a mortise lock, the 7240 is the wrong strike. Note it is fail-secure only, so the latch stays held when power drops and the outside lever or knob still needs a key.
2) What size cutout does the Adams Rite 7240 strike need in the jamb?
The faceplate measures 1-1/4 inch by 4-7/8 inch (31.8 mm x 123.8 mm), which is the standard ANSI strike prep footprint, and the case behind it is 1 inch x 3-3/8 inch x 1-5/8 inch deep (25.4 mm x 85.7 mm x 41.3 mm deep). The 1-5/8 inch depth is the number that matters on a retrofit: the jamb pocket has to take it and still leave room to route the wiring.
3) I need a strike that can be switched to fail-safe in the field. Is the Adams Rite 7240 the right one?
No. The 7240 is fail-secure only, so if the design calls for the door to unlock on power loss (a stair door on a mag-lock scheme, or an egress requirement written that way), pick a field-selectable unit instead. The Hager 2930 is a fire rated strike for cylindrical and mortise locks with field reversible fail safe/secure operation, and the Trine EN430 is fire rated with field selectable FS or FSE on a 4-7/8 in x 1-1/4 in faceplate. Keep in mind a fire-rated opening still has to be set fail-secure regardless of which unit you buy.
4) What is the closest equivalent to an Adams Rite 7240 electric strike for a cylindrical lock on a fire-rated opening?
The Von Duprin 4211 is the nearest one-for-one swap. Like the Adams Rite 7240, it is built for cylindrical locks and carries a fire rating, and it is a Grade 1 heavy duty strike with field-selectable 12/24 VDC. The 7240 is fire-rated and fail-secure for cylindrical locksets with up to 5/8 inch latchbolt projection, in a 1-1/4 inch x 4-7/8 inch faceplate. Where they differ is voltage handling: the 4211 is field-selectable between 12 and 24 VDC in one unit, while the 7240 voltage is fixed by the part you order, with 12 VDC, 24 VDC, 12 VAC and 24 VAC all available.
5) Can I use an Adams Rite 7240 on an exterior gate or a door with vertical rod exit hardware?
No. The 7240 is a fire-rated fail-secure strike for hollow metal jambs with cylindrical locksets and a latchbolt up to 5/8 inch projection. For a gate, the Camden CX-ED1959 Series is an outdoor rated electric gate strike, though it is not fire rated. For surface vertical rod exit hardware, the HES Folger Adam 310-4-2 is a complete Grade 1 strike pac built for surface vertical rods, also not fire rated. Neither is a substitute for the other, and neither belongs on a rated opening.
6) I need a fire-rated electric strike that will take either a cylindrical or a mortise lock. What should I use instead of the Adams Rite 7240?
The Adams Rite 7240 is a cylindrical-lock strike for latchbolts up to 5/8 inch projection. If the openings on the job mix cylindrical and mortise locks, the Hager 2930 is a fire-rated Grade 1 strike for cylindrical and mortise locks with 12/24 VDC dual voltage, and the Von Duprin 6400 is a Grade 1 modular strike for mortise or cylindrical locks with a 3-hour UL 10C fire rating in fail-secure. Either lets you standardize one strike model across both lock types instead of stocking two.
7) Which strikes look like alternatives to the Adams Rite 7240 but will not work on a cylindrical latchbolt?
Several strikes in the same family are prepped for different hardware. The Securitron MUNL is a mortise unlatch strike, Grade 1 and fire rated, but it is made for mortise locks rather than cylindrical. The SDC 30-4 Series takes a 3/4 inch Pullman latchbolt on a rim mount, and the SDC 25 Series is built for 1/2 inch latchbolt compatibility. The RCI 15BS is an economy fail-secure strike for a special offset latch entry and is not fire rated. The Adams Rite 7240 is specifically a fire-rated fail-secure strike for cylindrical locksets with up to 5/8 inch latchbolt projection, so none of those four cross over.
8) Can I get a latch monitor on the Adams Rite 7240 strike?
Yes, a monitored version is offered alongside the plain fail-secure one, in every voltage and both lip lengths. Order the monitored version when the access control head end or building management system needs to report door secure status, which is typical on healthcare, education and government openings where the panel logs whether a door actually relatched. The monitor option has to be specified at order time, so decide before you buy.
9) What kind of door frame does the Adams Rite 7240 electric strike mount into?
Hollow metal jamb, with the strike aligned to the cylindrical lockset latchbolt and enough clear space behind for the wire run. The keeper and strike lip are stainless steel, which is what you want on a high traffic commercial opening that gets pushed through hundreds of times a day.
10) Can I put the Adams Rite 7240 electric strike on an exterior gate or an outdoor opening?
The 7240 is specified for hollow metal jambs on interior commercial and fire-rated openings, so for a gate or a weather-exposed frame use a strike built for it. The Camden CX-ED1959 Series is outdoor rated for gate applications, though it is not fire rated, so do not use it where a fire label is involved.
11) I have to cover several different frame preps across a building. Is the Adams Rite 7240 a one-part-number solution?
Not quite. The 7240 comes with one faceplate size, 1-1/4 inch by 4-7/8 inch, so each opening has to already match that prep or get modified. If you are standardizing across mixed frames, a universal strike shipped with multiple faceplates covers more openings from one stocked item: the Camden CX-ED1689L-4 is a fire rated low profile universal with four faceplates, and the CX-ED1799L-8 is a fire rated dual monitor Grade 1 unit with eight. Where cutting the frame is off the table entirely, the Locknetics NC450 is a no-cut strike.
12) What else do I need to order to get an Adams Rite 7240 strike working?
Beyond the strike itself, you need a power supply matched to the version you order (12 or 24 volt, AC or DC, at 0.17A to 1.42A), the wire run to the jamb, and whatever releases it, a card reader, keypad, or push button on the access control side. If you ordered the monitored version, run the extra pair back to the panel for the status contact. The strike does not include the lockset, and the lockset on the door has to be cylindrical with a latchbolt of 5/8 inch or less.
13) Is the SDC 45F a substitute for the Adams Rite 7240?
They cover the same job on paper. The SDC 45F Series is a fire-rated electric strike with 5/8 inch latchbolt compatibility, matching the 5/8 inch latchbolt projection the 7240 is designed for. The difference is the faceplate: the 45F has a radius corner faceplate, while the 7240 uses a 1-1/4 inch x 4-7/8 inch plate. On a retrofit, the corner profile of the existing cutout decides which one drops in without rework.
14) What is a simpler alternative to the Adams Rite 7240 for a 5/8 inch latchbolt where fire rating is not required?
The SDC 15 Series is a value 5/8 inch latchbolt electric strike with 12/24 VDC operation, which matches the 7240 on latchbolt projection and voltage family without the fire-rated construction. The Trine 001 Series is a fail-secure light commercial strike with a 5-7/8 inch x 1-1/4 inch faceplate and is not fire rated. Keep the 7240 or another fire-rated strike anywhere the door assembly is rated; those two are for interior non-rated openings only.
15) I do not know the exact jamb prep yet. Is there a fire-rated strike with multiple faceplates instead of committing to the Adams Rite 7240?
The 7240 ships with a fixed 1-1/4 inch x 4-7/8 inch faceplate and a choice of 1-1/16 inch or 1-3/8 inch lip extension, so the prep has to be known. If you are specifying before the jambs are surveyed, the Camden CX-ED1689L-4 is a fire-rated universal low profile strike supplied with 4 faceplates, and the Camden CX-ED1799L-8 is a fire-rated Grade 1 dual monitor strike supplied with 8 faceplates. The Camden CX-ED1410 and CX-ED1420 Series are universal Grade 1 ANSI fire-rated strikes as well.
16) What else offers latchbolt monitoring like the monitored Adams Rite 7240?
The 7240 is available in a fail-secure/monitored configuration alongside the plain fail-secure version. For monitoring from another maker, the Dortronics 3300 Series is an electric strike with a latch bolt sensing switch, 12/24 VDC, with a strike plate for ANSI prep at 4-7/8 inch x 1-1/4 inch, which is the same faceplate size as the 7240. The Camden CX-ED1799L-8 is a fire-rated Grade 1 dual monitor strike, and the Hager 2945 is a fire-rated rim exit strike with a latchbolt monitor. The Dortronics unit mounts to ANSI prep; confirm the rating requirement of the opening before choosing among them.
17) The Adams Rite 7240 runs on AC as well as DC. Which other strikes accept AC power?
The 7240 is offered in 12 VAC and 24 VAC as well as 12 VDC and 24 VDC, so it can run off a transformer for buzz-in service. Among fire-rated peers, the Trine 004 is a fail-secure strike at 8-16 VAC with a 6-1/4 inch x 1-3/8 inch faceplate for throws up to 5/8 inch, and the Trine 2001 is a fail-secure strike at 16-24 VAC/DC with a 5-7/8 inch x 1-1/4 inch faceplate, also up to 5/8 inch. Both use a longer faceplate than the 4-7/8 inch x 1-1/4 inch on the 7240, so the jamb cutout is not the same.
18) Is there a fire-rated 24 VDC alternative to the Adams Rite 7240 for a pair of doors or a mortise lock at the same voltage?
For 24 VDC on a mortise lock, the Von Duprin 6210 is a heavy duty Grade 1 electric strike for mortise locks at 24 VDC fail-secure with a UL 10C fire rating, which matches the fail-secure operation and UL 10C certification of the 7240. For a double door, the Rockwood ESK-DBL is a Grade 1 fire-rated double door electric strike with a 3/4 keeper. The 7240 itself is available in 24 VDC as well as 24 VAC, 12 VDC and 12 VAC, so voltage alone is not a reason to move off it if the lock is cylindrical.
19) I want to avoid cutting the jamb. What is the alternative to the Adams Rite 7240 for a retrofit with no new prep?
The 7240 needs a 1-1/4 inch x 4-7/8 inch faceplate cutout in a hollow metal jamb with clearance for the 1 inch x 3-3/8 inch x 1-5/8 inch deep case and wiring access. The Locknetics NC450 is a no cut electric strike, which is the direction to go when the existing frame cannot be modified. The Locknetics MDS100 and MS100 are heavy duty strikes if the traffic level is the concern rather than the prep. Confirm the fire rating requirement of the opening separately, since the 7240 carries the UL 10C rating.
20) For a high traffic entrance, is there a heavier duty option than the Adams Rite 7240?
The Adams Rite 7240 uses a stainless steel bolt retaining keeper and strike lip and carries UL 10C fire rating for 3-hour single door installations. If the specification calls out a heavy duty rating explicitly, the Alarm Controls AES-100 is a Grade 1 heavy duty strike, and the Von Duprin 4211 is Grade 1 heavy duty and fire rated for cylindrical locks with 12/24 VDC field selection. On a rated opening, the fire rating narrows the choice to the 4211 or the 7240.
21) Is the Adams Rite 7240 strike rated for commercial or residential use?
Commercial. The 7240 is an ASSA ABLOY / Adams Rite product built for commercial building security, fire-rated openings, healthcare, education, government, industrial and multi-tenant residential access control. It is not a residential-grade door hardware item, and the fail-secure-only operation plus the UL 10C fire listing are what put it on specified commercial work.
