Redlands Magnetic Lock Installation Built Around a Safe Exit

What to know first in Redlands

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.

Work included on a typical visit

• Header-mounted maglocks on outswing doors. The standard configuration puts the magnet on the secure side of the header and the plate on the matching spot of the door. Through-bolts give the plate a firm grip. We set the plate loose enough to float and seat itself, then tighten the fasteners so nothing walks loose with slamming.
• 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.
• Aluminum storefront doors and shear locks. A storefront in the shopping centers around Redlands usually belongs to the landlord, so we plan the mounting around what is allowed. We measure the header, look at glass stops and hardware, and recommend surface or shear mounting based on depth, appearance and budget.
• 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. 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.

Local factors in Redlands

Wind, brushfire and planned power shutoffs are part of life in foothill communities. A maglock releases when power fails, so a long outage can leave a door unlocked unless you plan for it. We add battery backup sized for realistic outages, suggest a mechanical key lock for off-hours security where the rules permit, and explain what the door will do at each stage so you are never surprised.

Campus-area buildings use maglocks on study lounges, labs, maker spaces, bike rooms and glass-front student services offices. Heavy traffic and slamming are hard on plates and brackets, so we favor rigid mounting and bond sensors that report a magnet that isn't seating. Credentials turn over every term, which suits cards or mobile access better than keys. We also plan installation windows around the semester calendar.

Downtown office buildings and older storefronts in Redlands 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.

Common situations

• Say an earlier installer put a maglock on an office door with a card reader and nothing else. There is no exit button, no sensor and no link to the fire alarm. We'd survey the door, explain what is missing, add a sensor, a push button and a release relay, and tell you honestly which parts the building official will care about.
• 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.
• For example, a fitness studio has double glass doors off a shared hallway near San Bernardino County Museum. 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.
• Take a warehouse pedestrian door that opens outward onto a loading yard off Alabama Street. 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.

Step by step with Julian's Locksmith

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. 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. 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 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.
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.

What affects the cost

• 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.
• 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.

Mistakes to avoid

• 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.
• 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.
• 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.

What to do before we arrive

• 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.
• 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.
• 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 Redlands; we start with the exit.
• Keep banners, window film and signs off the header and away from the lock. Heat and adhesive can affect the magnet face and the sensor, and a sign can hide the release button. A tidy, visible door is a safer door.
