They wrapped the coil with insulating paper tape which held the heavier flying leads to the delicate coil wires. This tape was dried out and fell apart when I began evaluating (touching) it.
Folger Adam has been a major player in the electric locking industry for decades. They are now an Assa Abloy company under the HES tent.
I was pleasantly surprised when I called HES tech support and was able to obtain the solenoid through distribution and was able to quickly rehabilitate the strike assembly to pretty much perfect working condition.
I forced the strike back into the frame, and remounted it. It was necessary to fabricate a cover plate for the door frame.
I replaced the interface relay because, knowing its age and observing its condition, I felt it prudent to do so rather than wait for it to fail.
When I re-applied power to the system, the door operator opened the doors. But the problem was I hadn’t triggered it yet.
After more troubleshooting I discovered the inner handicapped button was in a shorted state, so it was constantly telling the operator to remain open and the strike was constantly energized.
Again, based on dates written on the equipment, it appeared that this switch had been in service for 20 years, so it was not unreasonable that it finally was worn out.
Once I replaced the switch, the door worked properly, and the customer, with whom I had shared the steps involved, was ecstatic.
The troubleshooting of this system was mildly interesting, but the effort required to get the electric strike out of the frame ranks this job in the top ten of botched installs by others.
HES Electric Strike
The HES (Folger-Adam) 310-6 is an industrial grade electric strike used on a pair of doors (without mullion) which are equipped with concealed, vertical-rod exit devices having a 1/2” or 5/8” throw latchbolt, when the spacing of the vertical rods is between 4” and 4-3/4”.
- UL1034, burglary-resistant listed
- DOD approved
- ANSI/BHMA A156.31, Grade 1
- New York City accepted
- .51 Amps @ 12VDC continuous duty
- .25 Amps @ 24VDC continuous duty
- Tamper resistant, heavy-duty construction
- Constructed entirely of stainless steel for strength and corrosion resistance
- Static strength 1,500 lbs.
- Dynamic strength 70 ft-lbs.
- Endurance 500,000 cycles
- Adjustable keeper to allow for door and frame misalignment
- Fail Secure (standard)
- Plug-in connector
- Five year limited warranty
- Fail Safe
- LCBMA - Latchbolt & Locking Cam Monitor with Auxiliary Switch
Note: Double-door models are available with four different center-to center dimensions between latchbolt keepers. Keepers are wide enough to compensate for vertical-rod exit bolts which may be as much as 3/8” off center-to-center dimension, either way.
When using a header mounted electric strike in conjunction with a vertical-rod device, it is necessary that:
- The bottom rod of the exit device be removed or made inoperative
- The latchbolt of the exit device be the “Pullman” or beveled type
- The latchbolt be free-latching and remain projected while the door is open.
- Mechanisms that hold the latchbolt retracted while the door is open, and automatically release it when the door is closed, must be removed or made inoperative.

The MC-25 (10MC25) is a Delay on Make / Delay on Break Time Delay Module used when either a magnetic lock or electric strike is installed on an automatic door. The delay on break timer will release the lock and then the delay on make timer will enable the door to open and be held open for a set period of time.
When a momentary contact closure is applied at the input wires, RELAY 1 ( 0-7 seconds) will become active. Approximately 0.5 or 1.5 seconds after RELAY 1 becomes active, a second relay, RELAY 2, ( 0-15 seconds ) will become active. The time delay will begin as soon as the input signal is released. If another momentary contact closure is applied to the input wires during the output of RELAY 2, the entire timing cycle will begin again. RELAY 2 will not drop out, but it will be reset to the full time delay. Also, the input voltage can be supplied through the contacts of RELAY 1 by changing the position of two jumpers on the MC-25.
The Altronix Model 6062 programmable timer is suitable for many functions that require a timed operation, e.g. access control applications.
Larco has developed transmitters and receivers designed for compatibility with virtually all automatic door operators and control devices.
