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

Magnetic Lock Installation in Rialto: what to expect

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.

What we can do on-site

• Inswing doors, brackets and offset mounts. Bracket choice is where installs go wrong. Inswing doors, deep headers and thick doors all change the geometry, and a cheap bracket that flexes gives up holding force. We use rigid kits, check them against the actual door, and avoid stacking parts that introduce play.
• 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.
• 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.
• 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.
• 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.

How Rialto shapes the job

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 Rialto 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.

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 Rialto 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.

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.
• 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.
• 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 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

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. 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.
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.

Pricing factors

• 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.
• Cable route and header access. Where power comes from affects cost as much as hardware. A supply close to the door is cheap; one across the building means heavier wire and more labor. Sometimes moving the supply saves more than any other decision. We look for the nearest ceiling space or closet during the survey.
• Permits, inspections and timing. Multiple doors, rated corridors and tenant improvement projects involve more coordination. We flag early which parts need a licensed electrician or fire alarm contractor, so your budget reflects the whole job and not only ours. When several trades touch one door, someone should own the schedule, and we are glad to coordinate.

Mistakes to avoid

• 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.
• Powering the lock from a cheap plug-in adapter. Adapters sag, overheat and fail, and when they do the door opens or the lock buzzes. Use a fused, regulated supply with suppression, in a ventilated spot, with labeled wiring. Voltage that sags under load also weakens the magnet, long before the supply fails outright.
• 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.

What to do before we arrive

• 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.
• Test the exit button and sensor monthly. Press the button and confirm the door releases; walk toward the door from inside and confirm the sensor does the same. Put the test on a calendar, because exit devices are exactly the part nobody notices until it fails.
• 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.
• 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.
