DynaLock 2800 Series Electromagnetic Door Holders

Model 2801 Floor Mount, Single Door

DynaLock 2800 Series Electromagnetic Door Holders are designed to hold self-closing fire or smoke barrier doors open until automatically released by fire alarm, smoke detection, or sprinkler systems. They can also be manually controlled wherever instant closing of doors is required for safety or convenience. Each door holder assembly consists of a floor or wall mounted heavy-duty electromagnet, a selfadjusting and pivoting armature, and all necessary mounting hardware. All models are field selectable to operate on 12 VDC, 24 VAC/VDC, or 120 VAC input voltage. Convenient screw terminals are provided for field hook-up. All holder models are UL listed. Optional Extension rods are available, to extend the armature projection, for installations where a wide standoff distance between the electromagnet and armature mounting locations exist. DynaLock 2800 Door Holders each provide 30-45 lbs. of holding force, allowing manual door closure when electromagnets are energized.

Standard Features
• 30-45 Lbs. holding force per door.

DynaLock 2801 – Frequently Asked Questions

1) Will the DynaLock 2801 door holder release the door automatically when the fire alarm goes off?
That is what the 2801 is built to do. It's a fail-safe electromagnet, so it holds a self-closing fire or smoke barrier door open and drops the door the instant power is cut by the fire alarm, smoke detection, or sprinkler system. Power loss of any kind releases it, so a building outage closes the doors too. It can also be dropped manually from a switch where staff need to close doors on demand.
2) Do I need to order the DynaLock 2801 in a specific voltage, 24V or 120V?
No, one part number covers all three. The 2801 is field selectable for 12 VDC, 24 VAC/VDC, or 120 VAC 60Hz, so you set it at install to whatever the fire alarm panel or building circuit gives you. Screw terminals are provided for field hook-up, and there's built-in spike suppression so de-energizing the magnet doesn't kick a transient back into the panel's solid state boards.
3) The gap between the floor magnet and the door is too big for the standard armature. What do I do?
Order an extension rod. DynaLock offers optional extension rods for the 2800 Series that lengthen the armature projection where there's a wide standoff between the electromagnet location and the point on the door the armature mounts to, which is common when the door swings well clear of the mounting point. They are a separate accessory, not included with the 2801, so they go on the order as their own line. The armature itself is self-adjusting and pivoting, so it takes up minor misalignment between the door face and the magnet without shimming.
4) I have a pair of doors in a corridor opening. Will one DynaLock 2801 hold both leaves?
No. The 2801 is the single door model and its 30 to 45 lbs of holding force is rated per door. A pair of doors needs a holder at each leaf, so that's two units on the order, each with its own armature on its own door. Check DynaLock's other 2800 Series models if you want a different mounting arrangement for the second leaf.
5) Should I use a floor mount or a wall mount electromagnetic door holder?
It comes down to what's behind the door when it stands open. The 2801 is the floor mounted single-door model in DynaLock's 2800 Series, which is what you want when the wall behind the open door is glass, glazing, a wainscot, or simply too far back to reach. A wall mounted holder is the cleaner install where there is solid wall at the right height and nothing to trip over, since a floor unit sits in the traffic path and in the way of mopping and floor machines. Corridor doors in hospitals and schools often go floor mount for exactly that wall reason.
6) How much holding force does the DynaLock 2801 have, and can staff still push the door shut while it's holding?
30 to 45 lbs of holding force per door, which is the point: it is strong enough to keep a self-closing door standing open against its closer, but light enough that someone can pull the door closed by hand without waiting for the alarm or cutting power. That matters in occupied buildings where a nurse or a teacher needs to shut a corridor door immediately.
7) What comes with the DynaLock 2801, and what else do I need to buy to finish the install?
Each 2800 Series holder assembly ships as the heavy-duty electromagnet, the self-adjusting pivoting armature that mounts to the door, and the mounting hardware, so the base install is covered out of the box. What isn't included is anything from the accessory line, extension rods included. You supply the power and the control wiring to the fire alarm relay; the unit has screw terminals waiting for it.
8) What finish does the DynaLock 2801 floor holder come in, and will it hold up in a busy corridor?
Satin Aluminum US28 is the standard finish on the 2800 Series holders, on heavy-duty die cast metal housings and faceplates. Optional sprayed finishes exist through the factory if you're matching something specific across a building. For a floor unit taking mop carts and foot traffic, the die cast housing is the part that matters, not the coating.
9) Will an electromagnetic door holder run up my power bill if I have dozens of them on standby?
Low power consumption is a design point on the 2800 Series holders, which matters exactly in the case you're describing: these sit energized 24/7 across every corridor door in a building, and on a system backed by batteries the draw is what sets how long standby lasts after the utility drops. Each 2801 also carries built-in spike suppression, so the moment they all de-energize on alarm, the collapse isn't putting transients into the rest of the access control and alarm electronics.
