Magnetic Lock Installation in Devore: Glass, Double and Office Doors

Short answer: Magnetic lock installation in Devore puts an electromagnet on the door frame header and a steel armature plate on the door. Power holds them together; cut the power and the door is free. We choose the holding force, mount both parts squarely, wire the power supply and release devices, and test that the door opens every way it must.

Magnetic Lock Installation in Devore, CA — Installing an electric strike for access control

Glass doors look wonderful and give a locksmith very little to work with. There is no mortise to cut, no solid frame to hold a strike, sometimes no frame at all. Magnetic lock installation is the usual answer in Devore: an electromagnet on the header, an armature plate clamped to the door, and no moving parts between them. When power flows, the door is held tight; when it stops, the door is free. That simplicity is also why the details matter. The wrong bracket, a header that flexes or a missing exit button can turn a neat install into a safety problem. Julian's Locksmith surveys the door first and tells you what will work.

Magnetic Lock Installation in Devore: what to expect

A magnetic lock has two parts. The electromagnet, a steel housing with a coil inside, mounts to the frame, usually on the header above the door. The armature plate, a flat piece of steel, mounts to the door at the matching spot. When the coil is energized, the plate is pulled onto the magnet face with a rated holding force, commonly around 600 pounds on single-door models and 1,200 pounds or more on heavy-duty ones. Cut the power and the magnetism collapses, so there is nothing to retract and nothing to turn. The plate sits on a flexible bushing so it can seat flat against the magnet even if the door moves a little. Small things matter. A gap the thickness of a business card cuts holding force, paint or rust on the faces weakens the grip, and a plate that is out of alignment can leave a door that looks locked but pulls open with a firm tug. Good magnetic lock installation is mostly alignment, solid fastening and clean wiring.

What we can do on-site

  • Header-mounted maglocks on outswing doors. On an outswing door with a sound header, the magnet mounts on the frame above the door and the armature plate mounts on the door face directly beneath. This is the cleanest magnetic lock installation: a straight bolt-up, short wiring and good alignment. We check the header for strength and anchor into solid material, not drywall.
  • Inswing doors, brackets and offset mounts. When a door swings into the secured space, the magnet and plate can't meet face-to-face without help. Bracket kits offset one or both parts so they close squarely. We pick the kit based on door thickness, header depth and swing, then test with the door fully open, closed and under pressure.
  • Fire alarm release and code review. Codes treat locked exit doors seriously. We explain what your building probably needs, point out where a fire marshal or plan reviewer should approve, and build the release path so the door can be tested at any time. If your door needs delayed egress or leads to a stair, we raise it before work starts.
  • Power supplies, battery backup and surge protection. Battery backup keeps a maglock holding through short outages and brownouts, though the batteries wear out and the door will release once they are exhausted. We size the battery to your preferences, explain the limits, and put a replacement date on the enclosure so the backup is not forgotten.
  • Door position switches, bond sensors and monitoring. Without feedback, a maglock looks locked even when the plate has shifted, the door is ajar or the power is off. Monitoring contacts close that gap. We add them to the doors that matter most, such as server rooms, storerooms and exit routes, and set alerts to suit your staff.

What's different about Devore

Inland heat stresses power supplies, batteries and plastic parts. A supply in an unvented ceiling can run hot and fail, and backup batteries age faster. Glass and aluminum doors expand in afternoon sun, which can shift plate alignment slightly through the day. We mount supplies where air moves, check alignment hot as well as cool, and put a battery replacement date on the label.

Wind, brushfire and planned power shutoffs are part of life in foothill communities. A maglock releases when power fails, so a long outage can leave a door unlocked unless you plan for it. We add battery backup sized for realistic outages, suggest a mechanical key lock for off-hours security where the rules permit, and explain what the door will do at each stage so you are never surprised.

Example situations

  • A typical call: a small company keeps its network equipment in a closet with a hollow-metal door and a keyed knob that everyone has copied. The manager wants a keypad. We'd mount an inswing bracket kit, run cable above the ceiling, set a short release time, and discuss whether a strike on the existing latch might be a better fit.
  • Picture a records room in a clinic. Only certain staff should enter, and the door is rarely used but must be monitored. We'd install a maglock with a bond sensor and a door-position switch, a reader outside and an exit sensor inside, plus an entry log, so the office manager can tell when the door was opened and whether it was left unsecured.
  • Consider an office whose doors fell open during a blackout. The cause was a small plug-in adapter with no backup feeding two maglocks. We'd replace it with a fused, regulated supply, add battery backup so the doors hold through short outages, and recommend a mechanical keyed lock for off-hours security, so protection no longer hangs on one adapter.
  • Think of a boutique with frameless glass doors on patch fittings and a floor closer. The owner wants after-hours card access but doesn't want holes in the glass. We'd use a glass-door bracket to clamp the armature plate, mount the magnet on a header plate above the door, hide the cable in the soffit, and add a push button and sensor inside so the door always opens for anyone leaving.

From your call to the finished job

  1. Survey the door, header and exit path. Before choosing a magnet, we check what you're attaching it to. A header that flexes, a door that sags or a closer that slams will undermine any lock. We note the problems and, if necessary, fix them before the lock goes in.
  2. Design the release path and quote. We decide which magnet or magnets, which brackets and which release devices the door needs: sensor, button, fire alarm relay and credentials. The written quote shows each piece and flags anything that needs an electrician, fire alarm contractor or building official before work begins.
  3. Mount the magnet and armature plate. Mounting is about alignment and solid anchorage. We check that the plate meets the magnet fully with the door closed and under slight pressure, that fasteners are tight and that nothing rattles loose. Glass doors use clamps; metal and wood doors use through-bolts.
  4. Run the power, sensors and fire alarm release. Wiring decides reliability. We use wire of the right gauge for the distance, land connections on terminals instead of twisting wires together, and fuse the supply. Exit devices get their own path, so one failed component can't trap anyone.
  5. Program credentials and set the timers. We enter cards, fobs or codes, set the release time and schedules, and decide what happens if someone holds the door open. A short release time discourages tailgating; a longer one helps people carrying loads. We choose a sensible compromise for your door and write it down.
  6. Test every release and hand over. Handover includes a short checklist: monthly button test, periodic cleaning of the plate and magnet face, and battery replacement every few years. We write the lock model, voltage and holding force on a label inside the enclosure, so future service doesn't start with guesses.

What affects the cost

  • Door type and mounting hardware. The door decides the bracket, and the bracket decides much of the cost. A standard header mount is inexpensive; custom or concealed mounting costs more. We show the price of each practical option so you can compare the clean look of a shear lock with a surface magnet.
  • Holding force and number of leaves. Each additional leaf or door adds a lock, a plate, brackets and wiring. Several doors in one visit share survey time and programming, which lowers the cost per door, but we still quote each opening separately so you can approve some doors now and others later.
  • Power supply, backup and controller. Maglocks draw power continuously, so the supply is a real component. A fused, regulated supply costs more than a plug-in adapter and does the job properly. Battery backup, a controller and readers add more. We build the list so you can add or skip items.

Practical tips before you call

  • Don't plan a maglock for a door that must stay latched in a fire. Rated doors, stair enclosures and some corridors have specific rules. Ask your fire marshal or building department before you buy hardware, and tell your installer what the door is and where it leads.
  • Review who holds access a few times a year. Cards and codes pile up as staff, vendors and contractors come and go, and every extra credential is a door that opens for someone. Remove what you no longer need and keep a short list of current holders.
  • Replace backup batteries on a schedule. A sealed battery typically needs replacing every few years, and a tired one may carry the lock for a short time instead of hours. Write the install date on the battery itself and put the next replacement on your calendar.
  • Tell your alarm company before we test the fire alarm release. Tripping the panel can notify the monitoring station and even the fire department, so the alarm contractor needs to schedule it or put the system on test. That is why this part of the job is arranged ahead of time.

Common errors that cost time and money

  • Assuming holding force equals security. A 1,200-pound magnet on a door with weak hinges, a thin frame or a gap at the edge can still be forced somewhere else. The door, the frame and the hinges matter as much as the magnet.
  • Mounting the magnet to a hollow, thin or flexible header. It may feel solid when installed and then give way under a hard pull. Anchor into steel, solid blocking or a backing plate that spreads the load across the frame.
  • Using a maglock where the door must stay latched. Fire-rated doors, some stairwells and other openings need hardware that latches positively, which a maglock does not do. Ask your building department before you specify one. If you are not sure how your door is classified, look for a label on the edge of the door or frame.

Frequently asked questions

Why does my door seem to stick after the magnet turns off?

That is residual magnetism, often caused by a worn or rusted armature plate, an over-tightened plate, or a plate with no flexible mounting. Cleaning the faces, loosening or replacing the plate and checking alignment usually cures it. It can also point to a failing lock or voltage problems, so we test the magnet before replacing parts.

Can you fix a magnetic lock that another installer put in?

Often. We check the mounting, the power supply and the exit chain: sensor, button and fire alarm release. Missing exit devices, weak brackets and marginal power are common. We explain what we found, what needs changing to make the door safe, and what your building official may want to see.

How do I secure the door after hours if power can fail?

Pair the maglock with battery backup for short outages, and consider a mechanical keyed lock for longer closures, as long as the exit rules for that door allow it. For doors that must stay locked through any outage, an electric strike or electrified lockset is a better fit. We walk you through which setup suits your door.

Do magnetic locks use a lot of electricity?

A single lock draws only a few watts, but it draws continuously while the door is locked, unlike a strike. Several doors on one supply add up, which is why we size the supply and any battery backup for the total load. A properly sized supply also keeps voltage steady at the magnet, protecting holding force.

Can a magnetic lock work on double doors?

Yes. Double doors use either two magnets, one on each leaf, or a combined unit for pairs, with a plan for the inactive leaf. Both locks release together on one circuit, and the exit sensor and button must cover whichever leaf people will use to leave. We map that out during the survey.

Do I need both a motion sensor and a push button?

On most exit doors, yes. The sensor releases the lock when someone approaches; the push button is a second, independent route that interrupts power directly. Some jurisdictions require both, and a single device is a single point of failure. Your fire marshal or building department has the last word, and we build to what they expect.

How far is Devore from your base?

Devore is about 8 miles from our San Bernardino base, roughly 14 minutes in light traffic. Arrival time depends on traffic and on the job the technician is finishing, so we give you an estimate on the phone before you commit.
