Answer:
No, the eSSL GL300 requires no hole drilling or cutout modification on the glass panel. It features a surface-clamping bracket design that mounts directly to 10 mm–12 mm glass panels, complemented by an integrated doorbell button, visual display screen, and random anti-peeping password protection.
A primary mechanical advantage of the eSSL GL300 Fingerprint Glass Door Lock is that it requires no hole drilling or specialized machining of the glass pane. Frameless tempered architectural glass cannot be drilled or cut on-site once cured; the GL300 resolves this challenge by utilizing a precision clamp-on mounting mechanism that grips standard 10 mm to 12 mm thick glass leaves securely.
Additional integrated hardware and functional differentiators include:
- Built-in Doorbell Ring: Front-facing capacitive doorbell trigger that sounds an internal chime through the integrated speaker, eliminating the need to install a standalone door chime.
- Anti-Peeping Virtual Password: To prevent onlookers from observing PIN codes, the system allows users to enter arbitrary numbers before or after their actual 6–10 digit code (up to 30 total keystrokes).
- Integrated Visual Screen & Voice Prompts: Provides visual and audible configuration feedback during administrator setup, credential enrollment, and volume adjustment.
- Normal Open Passage Mode: Can be activated via the interior thumb-turn knob or keypad commands (keys 2 and 8 after administrator unlock) for continuous unrestricted entry during high-traffic events.
