The initial call came in late on a Friday. The facilities management company wanted us to adjust the exit device controlling the main entry to a building housing a retail bank branch as well as eight floors of tenant’s offices. I was familiar with the building, since we had installed a HID Solo on...

Rather than allowing us to methodically troubleshoot the system, and rather than accept that there were major issues with the door itself, the client asked us to replace items in the exit device one at a time then see if that would do the trick. I recognized pretty quickly that doing the repair this way was going to run up the bill and probably not result in a happy ending, and asked my boss to intervene as a benevolent benefactor since the client was pretty much ignoring me.
It took about a month before the property manager finally got tired of the complaints from the end-user.
I have been dealing with old doors on banks for a long time, and realized that rather than dropping the door and either straightening it or replacing it ($$$); replacing the damaged the exit device (a discontinued model) and replacing and rewiring the special power supply specified for the exit device, a more cost effective solution would be to switch over to a electromagnetic lock solution.
The client finally said yes. We had the door converted in a day. The property manager reported that his phone stopped ringing as if by magic.
I selected the LOCKNETICS 390+ for this door. The 390+ exceeds ANSI/BHMA A156.23 Grade 1 standards with 1650 pounds of direct holding force, is UL listed as an auxiliary lock for a three-hour fire-rated opening and for burglary resistance
The 390+ surface-mounted electromagnetic lock is ideal for high security applications. My first experience with the unit was when it was still offered by Security Engineering, and I have been installing them for several years
The 390’s modular design employs a standardized circuit board with easy-to-install connectors, adjustable mounting brackets, integrated mounting screws, and slide-in architectural finish plates. A new armature housing holds the armature in place, eliminating the noise and sagging known with armatures, increasing the overall reliability of the product.
The armature housing also provides an aesthetically pleasing look, blending into the surrounding environment. Finally the armature housing holds the magnets for the DSM option without having to mount an additional plate to the armature, ensuring quicker, more reliable installations.
The 390+ is available for single, inswinging or outswinging, hollow metal, aluminum, and wood doors and frames and glass doors. The 392+ is available for pairs of hollow metal, aluminum, and wood doors and frames and glass doors without a mullion. The 391+ with split armature is used with pairs of hollow metal, aluminum, and wood doors and frames without a mullion.
LOCKNETICS #672 TouchBar
The 672 TouchBar is a request-to-exit device which releases electromagnetic or electronic locks when the bar is depressed. It is designed for easy installation, smooth operation and maximum durability.
I selected the illuminated version of the product to add for improved visibility, safety and appearance of the opening.
The “Push to Exit” signage provides an obvious exit indication for building occupants and the simplified design allows for reversing the signage in the field. The new pivoting bar design allows 1/4” activation and the 2 1/4” low profile provides ample clearance through the door.
The device’s rugged cast ramped end caps deflect blows and provide extra durability. The 672 uses switches and mechanical movement to actuate, providing a reliable solution for egressing. The 672 is also available with a DPDT output, so you can switch both the electromagnetic lock as well as send a REX signal to your electronic access control System if required.
ESSEX pushbuttons are highly reliable, and attractive. Using this pair of outputs, you can switch the lock and send a REX.
The bright LEDs are also configurable to indicate status of the locking device which is what I did on this project. The button responds to pressure rather than capacitance, and I’ve never gotten a complaint regarding sensitivity or operation.
SCHLAGE LOCKNETICS 510 POWER SUPPLY
The SCHLAGE LOCKNETICS 510 Series Power Supply is suitable for a wide range of applications, and I cannot recall one of them EVER failing on me. The output voltage is field selectable with an on board switch: 3amp @ 12 VDC and 2 amp @ 24 VDC.
The 510 is UL listed, filtered and regulated, has a built in battery charging circuit and is housed in a sturdy lockable metal enclosure.

Electromagnetic locks are sometimes regarded as an “idiot-proof locking solution” for unskilled installers or for use on problem doors.
