Two different questions a maglock can answer for the panel

A plain electromagnetic lock does one job: hold the door shut with a set amount of force until power is cut. It doesn't tell the access panel anything about its own condition. On an integrated job, the panel usually needs to know one of two things beyond that: is the door actually closed and the mag engaged, or has someone tampered with the lock or bracket. DynaLock builds separate monitor options for those two different questions, and picking the wrong one means the panel is watching for a condition that was never wired to report it.

The 2000 Series baseline

The DynaLock 2000 Series covered here is a 1200 lb holding force electromagnetic lock, designed for rated or nonrated doors and frames, with field selectable 12 or 24 VAC/VDC input, adjustable mounting, and a convenient wiring compartment. It's offered in single, double, and split-armature configurations for both outswinging and inswinging doors, which is the same base hardware whether or not a monitoring option gets added.

DSM2: door status, reported to the panel

The DSM2 configuration adds a door status switch to the base 2000 Series body. That switch reports whether the door itself is in a closed position, independent of whether the mag is powered or engaged. On a job where the access panel needs to distinguish "door is closed" from "door is unlocked but still sitting in the frame," or flag a door that's propped open past a set time, DSM2 is the option that actually feeds that logic.

HSM2: high security monitoring, a different signal entirely

The HSM2 configuration adds a high security monitor instead. Rather than reporting the physical door position, this option is built around confirming the lock's own secured condition, the kind of signal a facility specifies when the security concern is tampering with or defeating the mag itself, not just whether the door swung open. Don't treat DSM2 and HSM2 as interchangeable "monitor" checkboxes; they're answering different questions for the panel.

Matching the option to what the panel is actually programmed to do

Before specifying either monitor option, confirm what the access control panel's programming actually expects on that input. A DSM2 door-position signal wired into an input configured to expect a security-tamper signal won't produce useful data, even though the wiring will physically carry a signal either way. This is a coordination step between the door hardware spec and the access control programmer, not something the hardware alone resolves.

Single, double, or split armature: a separate decision from the monitor option

The 2000 Series is offered in single, double, and split armature models for both outswinging and inswinging doors, and that configuration choice is independent of whether the unit carries DSM2, HSM2, or no monitor at all. A double armature covers a pair of doors from one mag body; a split armature accommodates a gap or offset between the door and frame that a standard flush mount can't close cleanly. Pick the armature configuration for the opening's physical layout first, then decide which monitor option, if any, the panel needs on top of it.

Voltage flexibility is shared across the line

Both the DSM2 and HSM2 configurations, along with the base 2000 Series, carry the same field selectable 12 or 24 VAC/VDC input. That flexibility means the same mag body can be wired into different power supply setups without a different SKU for each voltage, but it also means confirming the field-selected voltage matches the actual power supply feeding it, the same discipline that applies to any electrified locking hardware on the job.

Adjustable mounting and a wiring compartment, on every configuration

Every unit in this line, monitored or not, ships with an adjustable mounting base and a wiring compartment built into the body. The adjustable base gives some tolerance for a frame that isn't perfectly square or a mounting surface that's slightly off from the original spec, which matters more than it sounds on a retrofit where the new mag has to land on hardware installed years earlier for a different unit. The wiring compartment keeps the low-voltage and monitor-switch wiring contained and serviceable rather than exposed at the head of the door.

Holding force doesn't change with the monitor option

Adding DSM2 or HSM2 monitoring doesn't change the 1200 lb holding force rating of the base 2000 Series body. The monitor is reporting status; it isn't adding or subtracting holding capacity. Size the holding force to the door and code requirement first, independent of which monitor option, if any, the job also calls for.

Pro tip from the counter: if a spec calls for "a monitored maglock" without naming which type, go back to whoever's programming the panel before ordering. It's a five-minute question that avoids pulling the wrong monitor option back off a door after it's already mounted. For sizing holding force across the DynaLock line generally, see our DynaLock holding force guide; for a gate application on the smaller 2013 body, our DynaLock 2013 gate guide covers that case.

Common questions

What's the difference between DSM2 and HSM2 on a DynaLock maglock?

DSM2 adds a door status switch reporting whether the door is physically closed. HSM2 adds a high security monitor focused on the lock's own secured condition rather than door position. They answer different questions for the access panel.

Does adding a monitor option change the holding force?

No. The 1200 lb holding force rating on this 2000 Series body is the same whether it's the base unit, DSM2, or HSM2. The monitor adds a status signal, not additional holding capacity.

Can I use DSM2 and HSM2 on the same lock?

Specify the option that matches what the access panel is programmed to receive. Confirm with whoever is programming the panel which signal type the installation actually needs before ordering.

What voltage does the DynaLock 2000 Series run on?

It's field selectable for 12 or 24 VAC/VDC input, which applies to the base unit and both the DSM2 and HSM2 monitored configurations.

Is this maglock rated for a fire door?

The 2000 Series is designed for both rated and nonrated doors and frames, but always confirm the specific fire door listing requirements with the door and frame manufacturer's documentation for the actual opening.
