HES HES-740-75 24D – Frequently Asked Questions
1) Will the HES Folger Adam 740-75 electric strike work with my mortise lock, or is it only for cylindrical locks?
Both. The 740-75 strike body accepts cylindrical and mortise latchbolt locks, so one part number covers the lever locks on your office doors and the mortise locks on your main entries. It is a commercial strike for hollow metal frames, not a residential product, and it is not intended for rim exit device latches.
2) Can I use the Folger Adam 740-75 electric strike on a fire rated door?
Yes, in the fail secure configuration only. The strike is UL 10C fire rated for 3 hours on a single door and 1-1/2 hours on a double door, fail secure only, and it conforms to CAN4-S104 (ULC-S104), NFPA-252 and ASTM-E152. Order the fail safe version and you lose the fire label, because a fail safe strike releases the latch when power drops. On a fire opening, specify fail secure and control egress with the lock trim.
3) Should I order the fail safe or fail secure version of the 740-75 electric strike?
Fail secure keeps the door locked when power is lost and is what you want on a perimeter or fire rated opening. Fail safe unlocks on power loss, which suits stairwell re-entry and doors that must free up during an alarm or outage. Both are offered in 12V and 24V DC. The fire ratings and the burglary listing apply to the fail secure build, so on a labeled door the choice is made for you.
4) Is a 740-75 electric strike strong enough for a high abuse door like a detention corridor or a school back entry?
Rated to 1500 lbs holding force and built entirely of stainless steel, this is an industrial grade strike meant for extreme heavy duty service. It is ANSI/BHMA A156.31 Grade 1 and carries the UL 1034 burglary resistant listing, which also makes it suitable for outdoor use. That combination is why it shows up on abuse prone openings where a standard commercial strike gets kicked apart.
5) Do I order the 12 volt or 24 volt version of the HES 740-75 strike?
Voltage is a fixed choice at order time, not a field selectable dual voltage board: pick 12 VDC or 24 VDC to match the power supply feeding the door. Access control panels and most dedicated door supplies run 24 VDC; standalone keypads and older intercom releases are often 12 VDC. Every combination of fail safe or fail secure, with or without the monitor option, is available in both voltages.
6) What does the LBMLCM option on the Folger Adam 740-75 do, and do I need it?
LBMLCM is the latchbolt and locking cam monitor. It reports two things back to your access control panel: whether the latchbolt is actually in the keeper, and whether the strike cam has relocked. Without it the panel only knows it energized the strike, not that the door secured behind the user. Specify it on monitored perimeter doors, secure storage, and anywhere you need a positive locked signal for an audit trail. On an unmonitored interior door it is cost you do not need. It is available on both fail safe and fail secure builds, in 12V and 24V.
7) What exactly am I getting when I order an SB740-75 strike body, and what else do I need for the job?
You are buying the strike body itself, the electrified keeper mechanism that mounts in the frame. It does not include the lockset, and it does not power itself: you supply a 12 or 24 VDC source and the release device (card reader, keypad, panel output, or push button) that switches it. The lock stays as is, since the strike works with the cylindrical or mortise latchbolt already on the door.
8) Which model number do I actually put on the purchase order for a Folger Adam 740-75 strike?
The base designation is HES-740-75 with the voltage appended: 740-75 12D or 740-75 24D for fail secure. An F in the string denotes the fail safe build (740-75 F 12D, 740-75 F 24D), and LBMLCM on the end adds the latchbolt and locking cam monitor. That gives eight orderable combinations in total. Distributors quoting this should confirm voltage, fail safe or fail secure, and monitor before the frame is prepped.
9) Is the HES 740-75 the right strike for a pair of doors, or is it single door only?
It works on either, but the fire label changes. Fail secure, the strike is UL 10C rated 3 hours on a single door and 1-1/2 hours on a double door. So a labeled pair carries the shorter rating from the same part. Confirm the pair's required label duration against that 1-1/2 hour figure before you commit the frame prep.
10) Will the 740-75 strike work on an access control system with door position and latch monitoring already spec'd?
Yes, and that is what the LBMLCM version is for. The strike is UL 294 (6th Edition) listed as an access control system component, and the latchbolt and locking cam monitor gives the panel a latch secured signal separate from your door contact. Match the strike voltage to the panel output, 12 or 24 VDC.
