Maglocks – the Hardware of Last Resort
What happens to a maglock when you lose power? It unlocks! How does that sound to you when trying to create a secure environment?
Access Control systems rely on electronic door hardware to unlock a door based on the presentation of a valid card or credential. All electronic door hardware relies on power to function. Most equipment runs off a 12V or 24V low voltage power supply that requires a 110V power source. In the event of a power failure, the hardware can be designed to either fail secure (locked) or fail safe (unlocked), or as I prefer to call it “fail UNsecure.” In most cases, you would want your doors to LOCK when power fails, thus supporting the security of your facility.
In the following list of electronic door hardware options, only one UNLOCKS when it loses power – the maglock. That’s one of the reasons it should be the last resort.
Electric strike – ideal for single doors when paired with a storeroom function lockset or exit device.
Electromechanical lockset – appropriate for single doors when incorporated into the construction design and procurement process; as this solution also requires a raceway in the door frame, a wired hinge or cable transfer method, and a raceway through the door from the hinge to the lockset.
Electric Latch Retraction exit device – appropriate for single or double doors, but most conveniently and cost effectively incorporated into a project when new doors and frames are being procured. It’s not impossible to retrofit an existing set of doors, but it is more costly.
Electromagnetic locks, also known as maglocks – the least appropriate solution for locking a door, because maglocks unlock when they lose power.
It would be prudent to consider the former options, rather than the latter, when evaluating your electronic door hardware options. After all, the whole point of investing in an Access Control system is to improve the security of your facility – not increase its vulnerability.
There are other reasons to avoid maglocks, which I’ll provide insight into in my next blog…
