Ontario Magnetic Lock Installation Built Around a Safe Exit

How this works in Ontario

Because a maglock has no latch, nobody leaving a building can operate a handle to get out; the lock has to let go for them. That is why magnetic lock installation on exit doors follows a pattern. A sensor above the door detects someone approaching from the exit side and cuts power. A push button near the door, wired to interrupt power directly instead of relying on a software setting, gives a second way out. The fire alarm system, and where required the sprinkler system, also cuts power so the door opens in an emergency, and losing power releases the lock by itself. Those requirements come from the building code California adopts, with local amendments, and the building department or fire marshal decides how they apply to your door. Delayed-egress locks, used in some care and retail settings, follow separate rules. We design to your jurisdiction's expectations and note which parts need review, so you aren't guessing when someone with a clipboard visits.

What we can do on-site

• Header-mounted maglocks on outswing doors. Most outswing steel and wood doors in Ontario can take a standard header-mount lock with little drama. The two tasks that matter are anchoring the magnet to something that won't flex, and aligning the plate within a small fraction of an inch. A weak anchor or a loose plate is where holding force disappears.
• Inswing doors, brackets and offset mounts. Not every door suits a maglock, and inswing doors are where we are most careful. Sometimes a bracket solves it neatly. Sometimes the geometry points toward an electric strike or other electrified hardware instead. We tell you which before anything is drilled.
• Aluminum storefront doors and shear locks. Surface magnets on aluminum can look bulky, and thin extrusions flex when the door is pulled hard. Backing plates spread the load. A shear lock hides the whole mechanism in the header, which many retailers prefer. We explain the tradeoffs and the cost difference before you choose.
• Power supplies, battery backup and surge protection. Nothing ruins a maglock install like a weak supply. If voltage sags, the magnet loses holding force; if the supply overheats, it quits. We mount supplies in ventilated spots, check voltage at the lock under load, and avoid sharing power with devices that could add electrical noise.
• 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.

How Ontario shapes the job

Shopping-center tenants use maglocks mostly on stockroom, back-of-house and office doors, and sometimes on glass entry doors after hours. The storefront frame belongs to the landlord, and exit rules apply to the rear corridor too. In Ontario centers we check delivery routes, fire alarm tie-ins and the way back doors are really used, because a maglock that traps an employee carrying inventory is a problem waiting to happen.

In new buildings, the best time for magnetic lock installation is during construction, when conduit, power and fire alarm relays can be planned before drywall. If your Ontario project is still going up, we'd rather coordinate with the electrical and fire alarm contractors from the start. Retrofits cost more and risk damaged finishes, while new work lets us choose mounting hardware to suit the frame.

Warehouse and industrial doors are heavy, often outswing steel on thin frames, and exposed to forklifts, dust and temperature swings. A maglock needs solid anchoring and a plate that stays aligned despite vibration. Many pedestrian doors on industrial sites in San Bernardino County fall under stricter life-safety rules because workers need dependable exits, so we check that early and may recommend a different lock.

Common situations

• 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.
• 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.
• 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.
• For example, a fitness studio has double glass doors off a shared hallway near Ontario Convention Center. 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.

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. 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.

Pricing factors

• Door type and mounting hardware. Heavy glass, wide double doors and odd headers all add to hardware needs. We would rather quote a solid kit that holds than a cheap bracket that flexes, because a flexing bracket costs holding force and, sooner or later, trust.
• Holding force and number of leaves. Maglocks come in different holding forces, and heavier-duty models cost more. Double doors need two locks. We match the magnet to the door and the risk instead of reaching for the biggest number, and we explain what holding force does and doesn't say about security.
• 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

• Take photos of the top of the door, the header above it and the edge of the door. Include any glass stops, closers or conduit in view. With those we can often pick the bracket kit and the mounting approach before we arrive.
• 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.
• 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.
• Think about off-hours security. A maglock lets go when power fails, so a blackout can leave a door unlocked. If that matters overnight, consider battery backup, a separate keyed lock where exit rules allow it, or an electric strike. Each has tradeoffs, and we will walk through them.

Common errors that cost time and money

• 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.
• 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.

Service in Ontario

Ontario is about 25 miles from our San Bernardino base, roughly 33 minutes in light traffic via I-215 North to the I-15 junction at Devore. When you call, you get an arrival estimate based on where the technician is and the traffic at that moment.

Rush hour on Archibald Avenue can stretch a drive considerably. We'd rather give you a realistic arrival window than an optimistic one, and we'll call you if a closure or a crash changes the plan.
