Magnetic Lock Installation in Bellflower: Glass, Double and Office Doors
Short answer: A maglock has no latch, so exit rules drive the design. For people to leave without special knowledge, an exit-side motion sensor, a push button and a fire alarm release normally cut power to the lock, and a power failure frees the door. Your fire marshal or building department has the final say, and we design around it.

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 Bellflower 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.
How this works in Bellflower
A magnetic lock draws power the whole time the door is locked, usually from a 12 or 24 volt DC supply, and that supply becomes the heart of the system. A good install has a regulated, fused supply, suppression on the lock circuit so reader electronics don't pick up noise, and a relay arrangement that lets the fire alarm cut power. Battery backup keeps doors locked through short outages, but batteries age and need replacing every few years. A door-position sensor and a bond sensor, which confirms the magnet is actually seated, tell the system when a door is truly secure. In a sound design the reader or keypad tells the controller to release the lock, but the controller does not hold the only path to the exit. The sensor, the button and the fire alarm each have their own independent route, and that separation keeps the door safe when something fails.
How we can help in Bellflower
- Frameless and tempered glass doors. Frameless glass has no stile, no hole and no margin for error. A glass-door bracket holds the armature plate with a clamp and rubber gaskets, and the magnet goes on a header, a sidelight or a mounting plate. We check glass thickness and pivot condition, because a sagging pivot defeats any magnet.
- Double doors and paired magnets. A pair of doors can use two single magnets, a double-door unit on a shared header, or a magnet on one leaf with flush bolts on the other. The best choice depends on which leaves open, how often, and what the code expects. We map that out during the survey.
- Fire alarm release and code review. Where a fire alarm panel exists, the maglock must drop out when it sounds. We wire the lock's supply through a relay or listed release, document it, and coordinate testing with whoever services your alarm. The panel connection itself may need a fire alarm or low-voltage contractor.
- 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.
- 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 Bellflower shapes the job
Apartment complexes use maglocks on glass-door fitness rooms, leasing offices, package rooms and clubhouses. Residents' expectations are simple: the door opens when they badge, and it opens from inside. Management needs logs, easy credential changes and a way to find a door left ajar. We install door-position switches and clear exit buttons, and we ask early where the fire marshal wants alarm integration.
Downtown office buildings and older storefronts in Bellflower often have tall glass doors, narrow aluminum headers and landlord rules about visible changes. Magnetic lock installation there is as much about appearance as strength: a concealed shear lock or a slim surface magnet with tidy cable routing. We work out the landlord's requirements first, because many downtown leases require approval before anyone drills the frame or runs cable through common areas.
School offices, childcare centers, churches and youth-sports buildings in Bellflower 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.
Example situations
- Take a warehouse pedestrian door that opens outward onto a loading yard off Alondra Boulevard. 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.
- For example, a fitness studio has double glass doors off a shared hallway near T. Mayne Thompson Park. Members badge in, and the owner wants evening entry without handing out keys. We'd fit a magnet on each leaf, wire both to a card reader and controller, add sensors and a push button inside, and connect a fire alarm relay with the landlord's alarm contractor.
- Imagine an aluminum storefront in a strip center with a header only a few inches deep. The tenant likes the look of a concealed lock. We'd compare a surface magnet with a backing plate against a shear lock, explain the cost difference and the header depth required, and get the landlord's approval before drilling a frame they own.
- 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.
From your call to the finished job
- Survey the door, header and exit path. We look at the door type, how it swings, the header and frame, the glass, the closer and the hinges. Then we trace how a person leaves: where they stand, what they reach for and what could stop them. The exit comes first because everything else depends on it.
- Design the release path and quote. A good design starts with the exit. We list every way the door releases, then add the credential that lets people in. You see the quote door by door, with notes on what could change. Nothing is drilled until you have approved it.
- 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.
- 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.
- Program credentials and set the timers. We set the door-held-open alarm, the lock's release delay and the sensor's hold time so they work together. Then we check that a credential, a button press and a sensor trigger each behave properly when tried separately and in sequence.
- 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.
Pricing factors
- Door type and mounting hardware. A steel outswing door with a solid header is the simplest mounting. Glass doors need clamp brackets, inswing doors need offset kits, and aluminum storefronts may need backing plates or a concealed shear lock. Mounting hardware is often the biggest single part of the price, so we choose it first.
- Exit devices and fire alarm interface. Fire alarm interface varies. Some buildings have a simple relay available; others require the alarm contractor to do the work or sign off. We tell you which situation you are in during the survey, so the schedule and budget account for it.
- 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.

Advice before you book
- Keep the magnet and plate faces clean. Wipe them with a dry cloth. Paint, tape, stickers and grease all widen the gap and reduce holding force. Never paint the faces, and don't cover them with decorative trim. A magnet that seems to have lost its grip is often just dirty or misaligned, so check those first.
- 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.
- Stand at the door and ask yourself: if the lights went out and I had never been here, could I leave? If the answer needs a sign, a hidden button or a staff member's help, the design isn't finished. Say so when you call us in Bellflower; we start with the exit.
What not to do
- 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.
- 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.

Frequently asked questions
Can a maglock be used outdoors?
Only models rated for outdoor exposure. Rain, dust, salt air and sun wear out standard indoor magnets. Outdoor-rated units, sealed wire entries and drip protection help, and corrosion-resistant plates matter near the coast. Exterior doors also see more wind and slamming, so the mounting has to be rigid, with the wire entry sealed against water.
Should I choose a maglock or an electric strike?
If the door has a sound latch and you want free exit, key override and a door that stays locked in an outage, a strike is usually better. If the door is glass, double or has no frame to cut, or the latch can't be used, a maglock fits. We compare both for your door as part of access control installation.
How do you confirm I'm allowed to modify my door?
Before we modify a door or lock, we verify ID and proof that you own, lease or manage the property, and tenants should have their landlord's approval for drilling the frame. It protects you as well as us. Our license is LCO7891, issued by BSIS, and you can verify it at search.dca.ca.gov.
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.
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 I need a permit for a magnetic lock?
Possibly. Locking an exit door is a life-safety change, so some buildings require a permit, plan review or inspection, while others only want the fire alarm release tested. We tell you what we expect, and your Bellflower building department or fire marshal confirms. If a fire alarm or electrical contractor is needed, we flag that in the quote.
How far is Bellflower from your base?
Bellflower is about 57 miles from our San Bernardino base, roughly 62 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.
