Answer:
The Biomax SA72 features an integrated digital backlit keypad and supports three distinct verification modes: Proximity Card, numerical PIN Code, and dual-authentication Card + Code. It also features rapid short-circuit protection on the lock output triggering within 100 microseconds.
The Biomax SA72 combines both credential reading and numerical PIN authorization in a single standalone security housing. Key differentiating hardware and operational capabilities include:
- Digital Backlit Keypad: Integrated backlighting ensures clear numeric visibility and trouble-free operation in dark, unlit, or low-ambient indoor/outdoor entryways.
- Triple Verification Logic: The controller can be programmed for three distinct authentication workflows: entry via Proximity card only, entry via numerical keypad PIN code only, or dual-factor entry requiring both Card + PIN code sequentially for higher security perimeters.
- Circuit Safety Protection: Built-in electronic short-circuit protection safeguards the internal switching circuit and power supply, responding in 100 µs or less during line fault conditions.
