C3-400 Plus Buyer FAQs
How should I specify C3-400 Plus for 4-door access?
Send a door schedule showing readers on each side, lock type, exit buttons and sensors. Confirm the complete channel and reader arrangement before ordering.
Can my existing RFID and QR readers be reused?
Provide reader models, credential formats and required interface. Confirm compatibility, protocol settings and firmware for the proposed configuration.
Does an access controller power every door lock directly?
Do not size lock power from door count alone. Provide voltage and current for each lock and confirm power supply, relay wiring and backup requirements.
Are software and visitor QR credentials included?
Confirm the management software version, licence scope and credential-issuing workflow. Ask which services and accessories are covered by the quotation.
What should be tested during commissioning?
Test valid and invalid credentials, direction rules, exit inputs, door status and emergency behavior. Confirm logs, time settings and recovery procedures.
