HES UNL-24 – Frequently Asked Questions

1) Will the HES UNL electric strike fit an existing ANSI 4-7/8 inch strike cutout without cutting the jamb?
That's the whole point of the UnLatch. The UNL drops into a standard ANSI 4-7/8 inch strike prep with no cutting or altering of the jamb, and the install is fully concealed once the faceplate is on. Faceplate is 4-7/8 inches and the strike body depth is 1-1/2 inches, so confirm you have that much room behind the prep in the frame.
2) Does the HES UNL work with a cylindrical lockset, or do I need a mortise strike?
The UNL is built for cylindrical and tubular locksets with a latchbolt, and it takes a latchbolt up to 5/8 inch. If your opening has a mortise lock, use the Securitron MUNL Mortise UnLatch instead. The UNL will not accept mortise lock hardware.
3) Can I use the HES UNL on a fire rated door?
Yes. The UnLatch strike is UL 10C Listed for 3 hour single door, CAN/ULC Listed to CAN4-S104, and compliant with NFPA-252 and ASTM-E152 for fire doors. It carries ANSI/BHMA A156.31 Grade 1 with function codes E09321, E09322 and E09323. Note that on a fire door the strike must be fail secure, so if you order the FSUNL module set it accordingly.
4) Is the HES UNL fail safe or fail secure?
As shipped the UNL is fail secure. Adding the Securitron FSUNL Fail Safe UnLatch module makes it field selectable for either fail safe or fail secure, and on loss of power it runs a full unlatch or latch cycle depending on the mode you set. The FSUNL is a separate item, so add it to the order if you need fail safe on that opening.
5) What do I need to specify when ordering the HES UNL UnLatch strike?
Two choices: voltage and finish. Voltage is 12VDC or 24VDC, and finish is 626 satin chrome or 613 oil rubbed bronze, both offered on either voltage. Part numbers run UNL-12, UNL-24, and the bronze versions UNL-12-10B and UNL-24-10B. If you want fail safe capability, order the FSUNL module alongside it.
6) Can I mount the HES UNL on an exterior gate or a door exposed to weather?
No. The UnLatch is not outdoor rated, so keep it to interior openings and weather protected exterior frames. Operating range is -10 to +125F [-29 to +52C]. For a genuinely outdoor or gate application, the Camden CX-ED1959 Series is outdoor rated.
7) What else could I use instead of the HES UNL for a cylindrical lock on a fire rated frame?
A few Grade 1 fire rated options for cylindrical locksets: the Von Duprin 4211 in 32D is fire rated Grade 1 heavy duty with 12/24 VDC field-selectable voltage, and the Hager 2930 is a fire rated Grade 1 dual voltage strike that handles both cylindrical and mortise locks with field reversible fail safe/secure. The Adams Rite 7240 is fire rated for cylindrical locksets with 5/8 inch latchbolt projection. What none of those match is the UNL's motorized pre-load release and its windstorm listing, so if the opening is under stack pressure or on a windstorm spec, stay with the UnLatch.
8) The opening is an aluminum storefront jamb - can the HES UNL be used, or is there a better strike?
The UNL is built for cylindrical locksets with a latchbolt and drops into a standard 4-7/8 inch ANSI strike prep, which is hollow metal and wood jamb territory. For aluminum jambs, the Adams Rite 7100 Series and the Adams Rite 7160 are made for aluminum jambs with a 1-1/4 inch by 4-7/8 inch faceplate. Neither Adams Rite model carries a fire rating, so on a fire rated aluminum opening neither of those is the answer.
9) What is the mortise lock equivalent of the HES UNL UnLatch electric strike?
The Securitron MUNL Mortise UnLatch electric strike is the mortise counterpart. The HES UNL is built for cylindrical locks with a latchbolt, so on an opening with a mortise lockset the MUNL is the one to specify. Both are Grade 1 and fire rated, so a facility standardizing on UnLatch operation can run UNL on the cylindrical openings and MUNL on the mortise openings without changing platforms.
10) What is a straight cross-brand equivalent to the HES UNL for a cylindrical lock on a fire rated opening?
The Von Duprin 4211 32D is the closest like-for-like: a Grade 1 heavy duty electric strike for cylindrical locks with 12/24 VDC field-selectable operation and a fire rating. The HES UNL matches on Grade 1, fire rating, cylindrical lock type and 12/24 VDC. The Hager 2930 is another Grade 1 fire rated option and covers both cylindrical and mortise locks with 12/24 VDC dual voltage.
11) The door has a rim exit device, not a cylindrical lock - what should be used instead of the HES UNL?
The UNL is made for a cylindrical or tubular lockset with a latchbolt, so a rim exit device needs a different strike. The Hager 2945 is a fire rated rim exit strike with field selectable fail safe/fail secure and a latchbolt monitor. The SDC 30-4 Series is a rim mount electric strike for a 3/4 inch Pullman latchbolt in stainless steel construction.
12) What looks like a substitute for the HES UNL but will not work on the same opening?
Several strikes sit in the same category without covering the same job. The SDC 25 Series is built for a 1/2 inch latchbolt, where the UNL accommodates up to 5/8 inch. The RCI 15BS is an economy strike for a special offset latch entry with fail secure operation and no fire rating, so it neither matches a standard cylindrical prep nor a fire rated opening. The Von Duprin 6210 is a 24 VDC fail secure strike for mortise locks, not cylindrical. The Trine 004 runs on 8-16VAC with a 6-1/4 by 1-3/8 inch faceplate, which is a different power source and a different prep than the UNL's 12/24 VDC and 4-7/8 inch faceplate.
13) What is the alternative to the HES UNL for a pair of doors with an inactive leaf?
The Rockwood 310-1 Series double door electric strike with a 3/4 inch keeper is the double door option. It is Grade 1 and fire rated, matching the UNL's Grade 1 and fire rating, but it is configured for a double door opening where the UNL is a single door strike for a cylindrical lockset in a standard ANSI 4-7/8 inch prep.
14) Which electric strikes handle a door under pre-load or wind pressure the way the HES UNL does?
The HES UNL is preload capable, releases under pre-load, and is windstorm rated - UL listed to ANSI/SDI-BHMA A250.13 at 60 PSI windstorm, plus ANSI/BHMA A156.31 Grade 1. Within the same family, the Securitron MUNL is the mortise version and is Grade 1 and fire rated, and the description covers both UNL and MUNL under the windstorm latching hardware listing. For a cylindrical opening under pressure, the UNL is the one; for a mortise opening under the same conditions, the MUNL.
15) How much current does the HES UNL draw, and what size power supply do I need?
Continuous draw is 40mA on both 12VDC and 24VDC. Operating draw is a minimum of 300mA at 12VDC and 200mA at 24VDC. Size the supply with headroom for startup inrush, 1 to 3 amps, or the strike may not release cleanly against pre-load. It's continuous duty, so it can sit energized indefinitely in a fail safe configuration.
16) Does the HES UNL tell my access control panel whether the door is actually latched?
A latch status sensor is standard, wired as a SPDT contact. That's latch status, not door position, so it reports whether the lock's latchbolt is actually seated in the keeper. Run a pair back to your panel input if you want the monitor point.
17) Is the HES UNL approved for windstorm or hurricane rated openings?
Yes. The UNL is listed as Windstorm Latching Hardware (ZHEM) under UL ZHEM.R25219, and UL listed to ANSI/SDI-BHMA A250.13 at 60 PSI. That is unusual for an electric strike and it is the reason this one turns up on coastal and institutional specs where most strikes get rejected.
18) Does the HES UNL keep the deadlatch working, or does it defeat it like some strikes?
Deadlatch function is maintained at all times, including full deadlatch support during operation. That matters on an exterior or secured opening, because a strike that lets the deadlatch plunger drop into the keeper pocket opens the lock to a credit card attack. The UnLatch holds the plunger supported.
19) Is there a simpler or lighter duty electric strike than the HES UNL for a 5/8 inch latchbolt?
Yes. The SDC 15 Series is a value 5/8 inch latchbolt electric strike with 12/24 VDC operation, and the SDC 45F Series is a fire rated 5/8 inch latchbolt strike with a radius corner faceplate. The Trine 001 Series is a fail secure light commercial strike with a 5-7/8 inch by 1-1/4 inch faceplate and no fire rating. The HES UNL differs in that it is motorized rather than solenoid, releases under pre-load, maintains deadlatch function at all times and includes a latch status sensor as standard.
20) Which electric strikes work with more than one faceplate prep, if the jamb prep across a building is not consistent?
The HES UNL is a single prep design: it fits the standard ANSI 4-7/8 inch strike cutout with no cutting or altering of the jamb. Where the preps vary door to door, the Camden CX-ED1689L-4 is a fire rated universal low profile strike supplied with four faceplates, and the Camden CX-ED1799L-8 is a fire rated dual monitor Grade 1 strike supplied with eight faceplates. The Von Duprin 6400 32D is a Grade 1 modular strike for mortise or cylindrical locks in satin stainless steel.
21) Which electric strikes besides the HES UNL provide latch monitoring?
The HES UNL includes an SPDT latch status sensor as standard. The Dortronics 3300 Series is an electric strike with a latch bolt sensing switch, 12/24VDC, and a strike plate for ANSI prep at 4-7/8 by 1-1/4 inches. The Hager 2945 includes a latchbolt monitor, and the Camden CX-ED1799L-8 is a dual monitor Grade 1 fire rated strike.
22) For a high traffic entrance, which heavy duty electric strikes compare to the HES UNL?
The HES UNL is a Grade 1 commercial strike with 1500 lbs holding force, motorized operation with no solenoids, and continuous duty rating. Heavy duty peers 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 32D, which is Grade 1, heavy duty and fire rated.
23) Which strike should be specified for a fire rated cylindrical lockset opening if the HES UNL is not available in the finish required?
The HES UNL comes in 626 satin chrome and 613 oil rubbed bronze in both 12V and 24V. Where a different finish is needed on a fire rated cylindrical opening, the Adams Rite 7240 is a fire rated electric strike for cylindrical locksets with 5/8 inch latchbolt projection, matching the UNL's up to 5/8 inch latchbolt. The Von Duprin 4211 32D is a Grade 1 fire rated strike for cylindrical locks with 12/24 VDC field-selectable operation.
24) What is the HES UNL made of, and will it hold up in a high traffic commercial entry?
Stainless steel body, rated commercial, ANSI/BHMA A156.31 Grade 1, and 1500 lbs [680 kg] holding force. It's motorized rather than solenoid driven and rated continuous duty, so it can be held energized on a fail safe opening without cooking a coil. For an apartment or office entry cycled all day this is the heavy end of the range.
