The eSSL GL300 digital electrical lock (KT reference KTI010040GL300, HSN 83014090) is an electronic access control solution engineered specifically for frameless glass door applications. Designing an access infrastructure around the GL300 requires evaluating structural glass dimensions, multi-modal credential verification parameters, power supply specifications, and operational environmental limits to ensure seamless site integration.
Glass Panel and Physical Mounting Compatibility
The eSSL GL300 is compatible with frameless glass doors featuring a glass leaf thickness between 10 mm and 12 mm. Because tempered architectural glass panels cannot be altered or cut after manufacturing, the GL300 utilizes a direct clamp-on installation assembly paired with a matching strike box. This mounting architecture requires no hole drilling through the glass leaf, preserving the structural integrity and tempered surface of the door.
Physical space planning on the door leaf must accommodate the lock body envelope dimensions of 131 mm in width, 200 mm in length, and 75 mm in depth (131 mm × 200 mm × 75 mm). With an overall unit weight of 1.6 kg, the assembly exerts minimal physical load on standard commercial hinges, pivots, and glass clamp fittings. The lock body is delivered in a Black color finish, aligning with contemporary commercial office partitions, conference room entries, administrative workspaces, and retail storefronts.
Credential and Access System Interoperability
The lock assembly functions as a standalone multi-factor authentication terminal supporting four distinct electronic verification modes: biometric fingerprint scanning, touch keypad numerical passwords, RFID card credentials, and wireless remote control access. This versatility allows commercial facility administrators to configure flexible authorization tiers across user groups.
- Biometric Compatibility: The integrated optical fingerprint sensor stores and validates individual user fingerprints within the device memory.
- RFID Card Compatibility: Integrated contactless card reading allows rapid credential validation for regular office personnel.
- Password and Keypad Compatibility: The touch keypad accommodates numerical passwords between 6 and 10 digits in length. It features full compatibility with anti-peeping virtual password strings, permitting up to 30 digits total entered before or after the true sequence to prevent passcode observation.
- Remote Control: Supports paired wireless remote controllers for administrative or reception-desk remote door release.
- Capacity Constraints: The internal memory stores 1 designated administrator credential and up to 99 regular user entries per credential mode, supporting a maximum combined credential capacity of 300 credentials across fingerprint, card, and password types.
- Auxiliary User Interface: The front exterior body includes an integrated doorbell button directly integrated into the verification interface, allowing visitors to signal personnel without secondary chime hardware.
Power Infrastructure and Electrical Compatibility
Primary electrical operation is powered by 4 × AA alkaline batteries (they are not included). The internal power management circuitry is configured specifically for standard alkaline chemistry; rechargeable batteries (they are not included) and non-alkaline primary cells (they are not included) are not recommended by the manufacturer due to voltage discharge curves. To maximize operational longevity between replacements, the device features an integrated power-saving circuit that automatically powers off the unit within 10 seconds without operation.
For emergency power supply during depleted battery conditions, the front lock assembly incorporates an external Micro USB emergency power port compatible with standard 5V DC mobile power banks. When internal batteries (they are not included) fall to low voltage levels, an audible low battery prompt alerts operators, and standard access operations are restricted until batteries (they are not included) are replaced or external 5V DC power is interfaced via the micro USB port.
Environmental and Operational Limitations
The eSSL GL300 is rated for ambient operational temperatures ranging between -25°C and 55°C. System planners must ensure the lock is not deployed in environments featuring high atmospheric salinity, severe industrial radiation, high magnetic fields, or ambient chemical vapors, as corrosive substances impair the internal touch keypad, visual screen, speaker, and optical biometric sensor. The hardware is certified under ISO, CE, FCC (FC), and RoHS manufacturing and technical compliance standards.
