ACCESS CONTROL · CCB #249201 · MILWAUKIE, OR

Every door has to answer the same question: who's allowed through.

Card, fob, mobile credential or biometric — one door or a whole campus. We wire the readers, locks and controllers, commission the system and hand you a list of who has access to what.

SECTION 01 / WHAT WE INSTALL

Four ways through a door, one wiring job.

Every credential type runs on the same low voltage backbone: a reader, a lock or strike, a controller, and cable connecting all three back to a panel.

SECTION 02 / RESTRICTED-AREA WORK

Cannabis and lab facilities have restricted areas by design.

We provide security and lab-compliance-related low voltage work in the cannabis sector, which usually means access control on the rooms with product, records or equipment in them, not just the front door.

SECTION 03 / WHERE THIS SHOWS UP

Anywhere a door needs to say no.

SECTION 04 / READ THE LABEL

Credential types, in plain terms.

General reference on the technology, not a recommendation for your building — the right credential depends on the door, the risk and who needs through it.

General industry reference, not a design for any specific door.

SECTION 05 / WHY IT MATTERS

An access list nobody can produce is not access control. It's a lock.

The point of the system is knowing who has access to what, not just that the door is hard to open. We hand over an audit list you can actually read.

SECTION 06 / FAIL-SAFE OR FAIL-SECURE

What your door does in a power outage is a decision, not a default.

A fail-safe door unlocks when power drops; a fail-secure door stays locked. Life-safety and code requirements often decide which one a given door has to be — that's a conversation for your walkthrough and your local fire marshal, not a one-size-fits-all answer.

ON SITE

Every reader is a cable run before it's a door.

The keypad, the reader and the mag lock are the part you see. Behind the wall is the same run, dressed and tested, that feeds the rest of the building.

SECTION 07 / DUE DILIGENCE

Before you hire anybody for access control.

Four questions worth asking any bidder, including us.

  1. Who has admin access after installation?You should, by default — not just the installer.
  2. Fail-safe or fail-secure, and who decided?Ask what your local code requires and how the installer verified it.
  3. Will you get a credential audit list?Who has access to what, handed over at close-out.
  4. Does it integrate with your cameras, or sit alone?A silo system is a missed opportunity. Ask before you buy.

SECTION 08 / THE RUN

From door count to a working credential list.

One cable. Five stations.

  1. 01

    Walk the doors

    Count openings, decide credential type, check code requirements.

  2. 02

    Design & quote

    Reader, lock and controller per door, and a number you can compare.

  3. 03

    Install

    Readers, locks and controllers wired back to the panel.

  4. 04

    Program & test

    Every door tested with real credentials before handover.

  5. 05

    Hand over

    Admin access and a credential audit list, in your hands.

SECTION 09 / THE OTHER TRADES

Door hardware is a coordination problem. We're used to it.

Facility & security managers

One contractor for the reader, the lock and the wiring, instead of three separate vendors pointing at each other.

Cannabis & lab-compliance operators

Restricted-area access control that fits the security and compliance work we already do in the sector.

General contractors

Door hardware timing coordinated with framing, finish and the rest of the trade schedule.

SECTION 10 / WHAT SHOWS UP ON SITE

Materials staged before the first hole gets drilled.

Readers, controllers, cable and hardware, counted and staged against the door list before install day — so the crew is pulling cable, not making a supply run.

READER PROTOCOL

Wiegand was never meant to be secure.

Wiegand is the decades-old signaling standard between a card reader and the door controller, and it sends the credential number across the wire in clear text with no supervision. A handheld device held against the reader wiring can capture and replay that data — a wiring-layer vulnerability that has nothing to do with the card itself. OSDP is the answer: an encrypted, bidirectional, supervised protocol that lets one wire run carry credential data both directions, report reader tamper, and receive door status back to the reader for LED and beeper control. It also runs on a two-wire RS-485 daisy chain, which cuts the pulls at multi-reader openings. Older buildings often have Wiegand pulled everywhere; the decision becomes whether to replace the run or bridge it with an OSDP-capable panel that still accepts the legacy readers, depending on what conduit already exists.

  • WiegandOne-way, unencrypted, unsupervised, with roughly a 500 ft practical run limit.
  • OSDPEncrypted, bidirectional, and supervised for reader tamper or a cut conductor.
  • RS-485 daisy chainDrops the wire count at multi-reader openings versus a home run to each reader.
  • Retrofit choiceRip and replace the Wiegand run, or bridge it with an OSDP panel that still accepts the legacy readers.

POWER BUDGET

The power supply gets sized before the lock gets chosen.

A fail-safe mag lock draws holding current continuously for as long as the door has to stay locked, while a fail-secure strike only draws current at the moment it unlocks — that difference alone can swing a panel's steady-state load several times over depending on how many mag-locked doors share the circuit. Battery backup sizing follows the same logic: a fail-secure opening keeps working through a power outage without any battery at all, but a fail-safe opening will swing open the instant power drops unless the supply carries enough battery capacity to ride through it. Every power supply gets a load schedule — each door's lock type, holding current, and duty cycle, checked against the supply's rated output and the battery's amp-hour rating, with headroom left for the panel and readers sharing that same circuit.

  • Fail-safe vs. fail-secureFail-safe locks draw continuous holding current; fail-secure draws only momentarily to unlock.
  • Battery backupA fail-secure opening rides out a power outage with no battery; a fail-safe one won't.
  • Load scheduleLists every door's lock type, current draw, and duty cycle against supply capacity.
  • Shared circuitReaders, panel boards, and REX devices share the same power budget as the lock.
  • Undersized supplyShows up as slow relock, chattering strikes, or brownout resets under load.

LIFE SAFETY INTERFACE

The handoff to the fire panel is one relay, wired right.

On an access-controlled door in an egress path, a mag lock can't stay locked just because a card wasn't presented — it has to release the instant the fire alarm system calls for it, with nobody touching a badge. That release runs through a dry contact or a monitored relay output from the fire alarm panel landing directly at the access control power supply, wired to drop power to the lock circuit on alarm, and on some systems on loss of AC power too. This isn't fire alarm design — it's making sure the access control side of that opening uses fail-safe hardware where code requires it, that the interface wiring is supervised so a cut conductor reports a trouble condition instead of failing silently, and that lock release gets tested and logged in the same drill that tests the alarm itself.

  • Access-controlled egress doorsRequire fail-safe locking hardware, released by the fire alarm signal.
  • Relay interfaceA dry contact or monitored relay runs from the fire panel into the access control power supply.
  • Supervised wiringReports a cut or shorted interface as a trouble condition instead of failing silently.
  • Tested with the drillLock release gets verified during the same fire drill/test cycle as the alarm system itself.
  • Loss-of-power releaseSome jurisdictions also require release on loss of building AC power, not only on alarm.

AUDIT TRAIL

The system's real output is a report, not a door opening.

A card reader unlocking a door is the visible part; the part a facility actually depends on is the log behind it — which credential opened which door, at what time, and whether access was granted or denied. That log is what gets pulled after an incident, what a lab compliance inspector or a healthcare surveyor asks to see, and what tells a building manager whether a terminated employee's badge is still active somewhere in the building. Getting that report right depends on how the system was configured from day one: permission groups built around job function instead of one-off exceptions per person, schedules that actually match occupancy hours, and anti-passback logic on controlled zones so a credential that's badged in can't be used to badge in again from a second door until it's badged out. None of that shows on a walkthrough — it only shows up when someone needs the report.

  • Event logRecords credential, door, timestamp, and granted/denied status.
  • Permission groupsBuilt by job function, not one-off per-person exceptions.
  • Anti-passbackRequires a badge-out before that credential can badge back in, blocking reuse at a second door.
  • SchedulesMatched to actual occupancy hours instead of left at factory-default 24/7.
  • Export formatMatters when an outside auditor or investigator requests records.

EGRESS HARDWARE

Free egress doesn't mean free of monitoring.

Code requires that anyone can leave through a controlled door without a key, a card, or special knowledge — but free egress doesn't mean the door goes dark on the inside. A request-to-exit device, usually a passive infrared sensor or a mechanical bar, releases the lock when it senses someone approaching from the secure side, and that release has to be reliable without being fooled by someone standing near the far side of the door or a draft moving a ceiling tile. Door position switches feed the panel a signal separate from the lock itself, so the system can tell the difference between a door propped open, a door forced open without a valid credential, and a door that unlocked normally and closed on schedule. Delayed-egress hardware, where code allows it, adds a fifteen-second alarm-and-delay before release — a narrow exception, not a default.

  • REX sensorReleases the lock automatically from the secure side, no credential needed.
  • Door position switchSeparate from the lock — tracks open/closed independent of lock state.
  • Forced vs. held-openThe system distinguishes a forced door (no valid credential) from a held-open door (propped past threshold).
  • Delayed egressCode-limited to about fifteen seconds, and a narrow exception, not a default.
  • Field tuningREX sensor placement and sensitivity get field-tuned to avoid false releases from adjacent motion.

PANEL ARCHITECTURE

How many doors live on one controller.

A multi-door panel in a head-end closet handles a bank of openings off one board, with door modules that each take a reader, a lock output, a REX input, and a door position input — efficient when the doors sit close together and the wire runs back to that closet are short. An IP-based single-door controller flips that: each opening gets its own small controller at the door, powered and networked over the same cable, reporting back over the building network instead of a home run of low-voltage cable. The choice isn't a brand preference — it's wire distance, closet capacity, and how the doors are laid out across the building. A single remote door two floors from the nearest panel is usually cleaner as a standalone IP controller than as a long pull back to a closet that's already full.

  • Multi-door panelOne board serves several openings, each with its own reader/lock/REX/DPS module.
  • IP single-door controllerPowered and networked at the door itself, no long low-voltage home run.
  • Decision driverWire distance and closet capacity, not brand preference.
  • Distance limitsTraditional reader wiring has practical distance limits that network-based doors don't share.
  • Expansion boardsGrow a panel in fixed door increments, not one door at a time.

DOCUMENTATION

Every opening gets a line on the door schedule.

Before any wire gets pulled, every controlled opening in the building gets a line on a door hardware schedule: door number matched to the architect's plans, lock function (fail-safe or fail-secure), reader type, whether it carries a REX device and a door position switch, which power supply circuit feeds it, and which panel and door module it lands on. That schedule gets walked door by door during rough-in to confirm the hardware ordered matches the opening it's going on, because a fail-safe lock on the wrong door is a life-safety problem, not a callback. It's also the document that outlives the installation — when a facility manager calls two years later about one door not releasing, the schedule tells whoever answers the phone which panel, which circuit, and which module to check before a truck gets dispatched.

  • Schedule contentsDoor number, lock function, reader type, REX/DPS presence, power circuit, and panel/module address.
  • Rough-in walkChecked door by door against the architect's opening schedule.
  • Mismatch riskA fail-safe/fail-secure mismatch on the wrong door is a life-safety error, not a punch-list item.
  • As-built referenceBecomes the reference for every service call after occupancy.
  • Door numberingMatches the architect's schedule, not an installer's own shorthand.
