Norco Magnetic Lock Installation Built Around a Safe Exit
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.

Many maglock calls start after something goes wrong: an inspector flags a door, a tenant says the exit button doesn't work, or a staff member finds a door that won't release. Magnetic lock installation in Norco should begin with the exit, not the lock. We identify how people leave, which devices release the door, what happens when the fire alarm sounds or the power fails, and whether your building department will want to see it. Then we choose the magnet, mount it, wire it and test it. If a lock someone else installed isn't right, we'll tell you what has to change.
How this works in Norco
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.
Work included on a typical visit
- 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.
- Frameless and tempered glass doors. Glass-front shops in Norco 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.
- 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. A maglock pairs well with almost any credential: cards, fobs, PIN codes, mobile credentials. What matters is that the controller's relay is rated for the lock and that the exit path never depends on that relay. We match the pieces, then test each credential type.
What's different about Norco
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 Norco 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.
Situations this covers
- Take a warehouse pedestrian door that opens outward onto a loading yard off North Drive. 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.
- 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.
- 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.
- A coworking space in a converted storefront wants evening card access on its double entry doors, while the landlord insists on no visible damage. We'd choose surface magnets with brackets mounted to existing holes where possible, hide cable behind trim, keep the work reversible, and give the landlord a simple drawing of what changed so the lease terms stay intact.
From your call to the finished job
- 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.
- 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.
- Mount the magnet and armature plate. We mark the layout, drill and anchor the bracket or backing plate into solid material, and mount the magnet square to the door. The plate goes on the door with through-bolts and a flexible bushing so it can seat flat against the magnet face, and we tighten everything to specification.
- Run the power, sensors and fire alarm release. The push button interrupts lock power directly, the sensor does the same through its relay, and the fire alarm relay does it for the building. We test each one independently by operating it with the others disconnected.
- 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.
- Test every release and hand over. Testing covers power on, power off, credential, push button, motion sensor and fire alarm release, with the door pulled hard against the magnet. We also test the batteries, if installed, and show you how to check the system monthly.
How we quote the job
- 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.
- Power supply, backup and controller. Backup power is the most common optional upgrade. It keeps doors secure through short outages, but the batteries need replacing and the door still releases when they run out. We explain the tradeoff and price it separately. Decide what you are protecting, and for how long, before choosing battery size.
- Cable route and header access. Short, accessible cable runs through a drop ceiling go quickly. Long runs, finished walls, concrete or fire-rated barriers take longer and may need other trades. We trace the route during the survey and quote the cabling as its own line.

What not to do
- 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.
- Skipping the alignment check. A plate that sits at an angle, or a gap wider than a business card, delivers only a fraction of the rated holding force. Tighten the plate with the door closed, then confirm the faces meet fully.
- Drilling tempered glass. Once glass is tempered it can't be drilled or cut, and any attempt can shatter the panel. Use glass-door clamps that grip the edge. If a door was drilled previously, we can judge whether existing holes can be used safely.
Practical tips before you call
- 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.
- 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.
- 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.
- 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.

Frequently asked questions
Can you put a maglock on a glass door?
Yes. Tempered glass can't be drilled, so we use glass-door brackets that clamp the armature plate to the glass without holes, and we mount the magnet on a header, sidelight or mounting plate. We check the glass thickness, the pivot or hinge condition and the closer first, because a door that sags won't seat against the magnet.
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.
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.
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.
What is magnetic lock installation?
Magnetic lock installation means mounting an electromagnet on the door frame and a steel plate on the door, wiring power to the magnet, and adding the release devices that let people leave. When the magnet is powered it holds the door shut; when power is removed, the door is free. We also program any reader or keypad and test every release path before we leave.
How far is Norco from your base?
Norco is about 29 miles from our San Bernardino base, roughly 33 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.
