Door-controller, reader and credential choices for new Keri systems and responsible upgrades of existing Keri hardware.
What this product family does
Keri offers NXT controller families, NXT-MSC Mercury-powered controllers, supported Authentic Mercury hardware and expansion/I/O options. The correct panel is chosen by software platform, door count, reader protocol, elevator or automation needs, enclosure/power design and the features required at the edge.
Products and decisions
| Product area | What it includes | Selection guidance |
|---|---|---|
| NXT / KB | Keri controller paths for Borealis and selected Keri deployments | Check cloud/software compatibility; the KB controller is Borealis-specific and does not simply substitute in every Doors.NET design |
| NXT-MSC | Mercury-powered Keri controller architecture with OSDP support in applicable designs | Useful where Mercury interoperability and advanced reader communications are project priorities |
| Readers | Keri and compatible Wiegand/OSDP reader families, including mobile-capable choices | Select by credential, environmental rating, mounting, keypad and secure-channel requirements |
| I/O and elevators | Expansion modules and supported elevator/control interfaces | Build an input/output schedule instead of assuming every panel supports every workflow |
Questions to answer before quoting
- List panel and module part numbers before recommending reuse
- Verify standby power and lock-power calculations
- Plan a credential-security upgrade rather than preserving weak badges by default
- Confirm supervised inputs, OSDP secure channel and offline behavior
- Who owns administration, backups, updates and recurring services?
- What must continue working during network, internet or power failure?
- Which opening, egress, accessibility and life-safety requirements apply?
- What training, documentation and preventive maintenance are required?

How to compare and specify this product family
For Keri NXT and Mercury Controllers, Readers and Credentials, the right model and architecture depend on the site, existing infrastructure and operating policy. A proposal should clearly document the following access-control system decisions before equipment is ordered:
- Number and type of controlled openings
- Controller, reader, lock and credential compatibility
- Cloud or on-premise administration and ownership
- Offline behavior, backup power and emergency operation
- Directory, HR, video, visitor and elevator integrations
- Licensing, cybersecurity, training and lifecycle support
Installation, testing and handoff
A site survey records each opening, door hardware, cable path, power, network, credential policy and integration requirement. The design then maps readers, controllers, locks, inputs, outputs and administrator roles to the operational workflow. Commissioning includes door-by-door functional tests, failure-mode and backup-power checks, permission and schedule tests, event verification, administrator training and as-built documentation. Product availability, subscriptions and supported integrations are confirmed for the current project before procurement.

Official Keri Systems software, firmware and support
Use the manufacturer links below for current software, firmware, release notes, manuals and technical resources. Boston High Tech links directly to official manufacturer portals and does not copy or host firmware files.
Before installing an update: verify the exact model, region, hardware revision, current version, required intermediate releases, licensing or support entitlement, backup and rollback plan, integrations and maintenance window. An incorrect firmware package or upgrade sequence can interrupt service, invalidate compatibility or prevent a downgrade. Coordinate updates for monitored, life-safety-adjacent or business-critical systems with the system administrator and an authorized specialist.
Some resources require a customer, dealer, certified-technician or active-support login. Cloud-managed products may update automatically and may not provide a public firmware file.
