Every opening matters
A reader is only one part of a controlled door. Review lock or strike, closer, hinge, egress, position switch, request-to-exit and fire interface.
Manage who can enter, when they can enter and how that access is audited.
Greater Denver and the Front Range

Products, interfaces and exact scope are confirmed after reviewing the facility.
A complete opening includes hardware, egress, power, programming and the network; video and identity workflows may add useful context.
Every controlled opening is a mechanical, electrical and software assembly. Verify lock behavior, safe egress, door position, request-to-exit, backup power and the credential workflow for new and departing users.
Train administrators on credential changes, reports, overrides and the process for a failed door.
We confirm existing conditions and customer responsibilities before finalizing products, interfaces, tests and the documentation needed to support the installed system.
A useful design connects components, people, failure conditions and a testable handoff.
A reader is only one part of a controlled door. Review lock or strike, closer, hinge, egress, position switch, request-to-exit and fire interface.
Compare local and cloud administration, controller resilience, credential type, mobile access, offline behavior, integration and lifecycle cost.
Map who approves a credential, where schedules and groups come from, how temporary access expires and how departures are handled.
Test valid and invalid credentials, forced and held door events, network loss, power loss and safe egress at each opening with the owner.
Five possible applications to explore during discovery. These describe capabilities and design scenarios, not completed customer projects.
Give a vendor time-limited access to a loading entrance without sharing a master key.
Separate staff, tenant and visitor permissions across multiple office floors.
Link a held-open door alert to the corresponding entry camera and response team.
Modernize a legacy controller while preserving safe egress and an approved migration path.
Remove departing employee credentials centrally and verify the audit record.
Representative equipment and working environments relevant to the scope.



Our pre-site safety review, field documentation and customer acceptance process help keep the installed condition visible to the people who will operate and maintain it. For access control, the closeout conversation should include: Test valid and invalid credentials, forced and held door events, network loss, power loss and safe egress at each opening with the owner.
We ask for the existing drawings, device inventory, network and power ownership, known deficiencies and the people who will use the system. The final scope and acceptance criteria follow those answers.
| Decision | What to confirm |
|---|---|
| Scope | Confirm the devices, areas and operating modes included in the work; record exclusions. |
| Dependencies | Every controlled opening is a mechanical, electrical and software assembly. Verify lock behavior, safe egress, door position, request-to-exit, backup power and the credential workflow for new and departing users. |
| Handoff evidence | Test valid and invalid credentials, forced and held door events, network loss, power loss and safe egress at each opening with the owner. |
