Magnetic Lock Installation in West Covina

Short answer: Magnetic lock installation in West Covina 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 West Covina, CA — Installing an electric strike for access control

A maglock has no latch to wear out, no bolt to jam and no keeper to align, which is much of the appeal. It is simply a strong electromagnet and a steel plate. That design suits server rooms, records rooms, stockrooms and offices in West Covina where a door has to stay shut against a hard pull but open instantly when someone needs to leave. The tradeoff is a dependence on power and a design that must put the exit first. This page explains how magnetic lock installation works, what we check on site, what the code expects and what usually changes the price.

What to know first in West Covina

Doors dictate the hardware. An outswing steel door with a solid header takes a standard header-mount lock easily. An inswing door usually needs a bracket kit so the magnet and plate meet squarely. Aluminum storefronts have narrow headers and thin extrusions, so the magnet may need a through-bolted backing plate or may be better as a concealed shear lock. Tempered glass can't be drilled once it has been made, so glass doors use clamp-style brackets that grip the glass without any holes. Double doors need either two magnets or a combined unit, plus a plan for the inactive leaf. Wood doors need through-bolts long enough to resist pulling out. We look at the door, the header and the swing during the survey and choose the mounting kit before you see a price, because it is often the largest piece of magnetic lock installation. If the header cannot carry a magnet, we say so and suggest another route.

What we can do on-site

  • Frameless and tempered glass doors. Glass-front shops in West Covina often have patch fittings, floor closers and a lock never meant to be electronic. A maglock with a glass clamp adds access control without altering the glass. We position the magnet where it looks neat and run the cabling where it stays hidden.
  • Aluminum storefront doors and shear locks. Aluminum storefront frames have narrow headers and thin walls. A surface-mounted magnet can need a backing plate inside the extrusion, while a concealed shear lock hides in the header and clamps the top of the door. Shear locks cost more and need the right header depth, but they leave a very clean look.
  • Double doors and paired magnets. On a double door, one weak side defeats the whole opening. We match the holding force to the heavier leaf, mount each plate where the door is stiff, and test by pulling at the weakest point. Wiring both locks on a single release makes them behave as one door.
  • Exit sensors and push buttons. A motion sensor above the door detects someone leaving and cuts power so the door opens. A push button, mounted near the door and wired to interrupt power directly, gives a second route out. We aim the sensor at the exit side and test it with people walking, carrying items and moving slowly.
  • Readers, keypads and controllers. Standalone keypads handle one or two doors affordably; networked controllers manage many doors with schedules and logs. Either way the maglock follows the controller, and the exit devices stay on their own path. We write down codes, schedules and wiring so a new manager can take over.

How West Covina shapes the job

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.

School offices, childcare centers, churches and youth-sports buildings in West Covina often use maglocks on glass entry doors so staff can control who comes in. Children and visitors must always be able to leave, which makes the sensor, button and fire alarm release central. We design for substitute staff and volunteers, label the exit button plainly, and keep the system simple enough for anyone to understand.

Dealerships use maglocks on key rooms, parts cages and glass doors between showroom and service areas. A key room is the most sensitive, since it holds every key on the lot. We pair the lock with logging, door-position monitoring and a clear exit, and tie it into your key-control routine so a door left ajar draws attention before it becomes a problem.

Common situations

  • Take a warehouse pedestrian door that opens outward onto a loading yard off Barranca Street. Forklifts bump it, and the frame is thin. A maglock may not be the best choice, because the magnet needs solid anchoring and a flexing frame loses holding force. We'd weigh a strike or an electrified exit device first, and use a maglock only if the frame can be stiffened.
  • A common puzzle: the door releases, yet it feels stuck for a second. That is residual magnetism, often from a worn armature plate, rust, or a plate tightened too hard. We'd inspect and clean the faces, check alignment, replace the plate or fit a spacer if needed, and verify the door falls free the instant power is cut.
  • 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.

How the visit works

  1. Survey the door, header and exit path. On site we measure door thickness and swing, header depth and ceiling access for cable. We ask who uses the door, when and how, and where the fire alarm panel and power sources are. Photos before the visit help, but nothing replaces seeing the door.
  2. Design the release path and quote. We also confirm authority to modify the door. We need ID and proof that you own or manage the property, and tenants should have their landlord's permission, since mounting a magnet means drilling the frame.
  3. Mount the magnet and armature plate. The magnet face and plate must meet flat. We check the gap, adjust the plate until contact is even, and clean both faces so no paint, dust or tape sits between them. Small gaps cost large amounts of holding force.
  4. Run the power, sensors and fire alarm release. Low-voltage cable runs from the lock to the power supply, sensors, button and controller. We route it through the ceiling or a raceway, keep power and signal wires neatly separated, and label both ends. Fire alarm relays go in the lock's power line and are tested with the alarm contractor.
  5. Program credentials and set the timers. Programming depends on the controller. A standalone keypad takes a few settings; a networked system takes a user list and schedules. We create the first credentials with you, show you how to add and delete them, and leave the settings recorded.
  6. Test every release and hand over. We walk through the door as a stranger would, looking for anything confusing. Then we show your staff the button and the sensor, give you the wiring record and tell you who to call about the alarm panel.

How we quote the job

  • Holding force and number of leaves. More force isn't always better. A magnet rated beyond what the door and frame can take adds expense without adding security, since the door will fail elsewhere. We choose a force that matches the door's weight, the frame's strength and the value of what is behind it.
  • Power supply, backup and controller. A single-door keypad system is a small project; a networked controller with software and several doors is larger. Credentials such as cards and fobs are an ongoing cost. We plan the system so it can grow without redoing the wiring.
  • Permits, inspections and timing. Scheduling flexibility helps. Work done in one planned visit during normal hours is simpler than a rushed one. We start at 6:30 a.m. every day, so many installs can be finished before a business opens. Tell us about inspection dates, tenant move-ins and opening days early, because our proposed schedule works backward from those.

Practical tips before you call

  • If you rent, ask the landlord in writing before anyone drills the frame. A maglock may need removal when you leave, so keep a copy of the wiring diagram, the model information and any hardware that was taken out. The next tenant, and your landlord, will thank you.
  • 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.
  • 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.
  • Walk the door as it stands. Does it close fully by itself? Does it sag? Does the closer slam it? A maglock can't fix a door that doesn't meet the frame. Adjust the hinges and closer first, because the plate and magnet need to meet flat every time.

What not to do

  • Wiring the exit button through the controller only. If the controller hangs or loses power to its logic, the button does nothing. The push button should interrupt lock power directly, so the door opens even if the access system is dead.
  • Installing the lock without an exit plan. A maglock with a card reader and nothing else can trap people if the controller fails while the lock stays energized. A sensor, push button and fire alarm release aren't optional on exit doors, and an inspector will look for them.
  • 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.

Frequently asked questions

How strong is a magnetic lock?

Single-door models are commonly rated around 600 pounds of holding force, and heavier-duty units reach 1,200 pounds or more. The rating assumes the plate sits flat against the magnet, so alignment matters. The door, hinges and frame also limit what the lock can resist, which is why we look at the whole opening instead of the number on the box.

Will a card reader or keypad work with a magnetic lock?

Yes. A reader or keypad signals a controller, which releases the lock for a few seconds. Cards, fobs, PIN codes and mobile credentials all work, as long as the controller's relay is rated for the lock. We connect the reader, set release times and programming, and test each credential type before we leave.

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.

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.

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.

Does a magnetic lock connect to the fire alarm?

Where a fire alarm system exists, the maglock normally drops out when it sounds, using a relay in the lock's power line. Some buildings add sprinkler or smoke detector release. The panel connection may need a licensed fire alarm contractor, and the release should be tested with them. We coordinate so testing doesn't surprise your alarm monitor.

How far is West Covina from your base?

West Covina is about 42 miles from our San Bernardino base, roughly 47 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.
