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

What to know first in Bloomington

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. 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.
• Double doors and paired magnets. Double doors need two locks or a combined unit, one per leaf, plus a plan for the inactive leaf. We align both plates and magnets so each pulls evenly, then check that the meeting edge keeps the leaves from flexing apart. Both leaves release together when power is cut.
• Fire alarm release and code review. A fire alarm release uses a relay from the panel to cut lock power when the alarm activates. We install the relay on the lock's power line and test it with your fire alarm contractor, who has to trigger the panel. When building rules require sprinkler release too, we plan for that.
• Readers, keypads and controllers. A reader or keypad tells the controller to release the lock for a few seconds. We connect the reader, controller and lock, set the release time, and configure schedules and credentials. Cards or codes can be canceled instantly, which is far easier than rekeying a door.
• Door position switches, bond sensors and monitoring. Propped doors defeat access control. A door-position switch with a timer can chirp or notify when a door has been left open too long, and a bond sensor flags a magnet that isn't holding. Both are inexpensive additions at installation time and tedious to add later.

How Bloomington shapes the job

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.

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 Bloomington 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.

Common situations

• 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.
• Take a warehouse pedestrian door that opens outward onto a loading yard off Alder Avenue. 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 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 I-10 and Cedar Avenue interchange. 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.

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. 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.
4. 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.
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

• 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. 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.
• Cable route and header access. Headers can hide surprises: steel, conduit, glazing channels or nothing solid to anchor into. We probe before committing, and our quote notes what we found and what might change once the frame is open. A header that turns out to be thin drywall or hollow aluminum means backing plates or a different mounting plan, and we would rather tell you that before drilling than after.

What not to do

• 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.
• 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.
• 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

• 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.
• Aim the exit sensor with care. It should see people approaching from inside, not passers-by outside or sunlight on a glass door. Seal gaps at the bottom of the door and keep paper, signs and decorations out of its view.
• 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.
• 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.

Getting to Bloomington

Bloomington is about 14 miles from our San Bernardino base, roughly 22 minutes in light traffic via Belmont Avenue and Palm Avenue to I-215 South, SR-210 West to the Riverside Avenue exit. When you call, you get an arrival estimate based on where the technician is and the traffic at that moment.

Commercial jobs on busy stretches like Valley Boulevard sometimes need a parking plan, especially for storefront doors or roll-up gates. Let us know about loading zones, red curbs or parking structures before we arrive.
