The eSSL GL300 (KT code KTI010040GL300) is a commercial-grade digital electrical lock engineered specifically for frameless glass door applications. Fabricated in a black finish with an overall form factor measuring 131 mm in width, 200 mm in length, and 75 mm in depth, the lock assembly carries an overall unit weight of 1.6 kg. Designed for direct non-destructive deployment, the mechanical clamping system eliminates the need for glass drilling or specialized panel cutting.
Frameless Glass Panel Preparation and Clamping Setup
Before physical mounting, the glass door leaf must be cleaned and verified against structural thickness requirements. The eSSL GL300 mounting clamp and its paired strike box are designed exclusively for glass panels with a thickness between 10 mm and 12 mm. Because the mechanism uses surface clamping, no hole drilling is required on the glass panel during mounting.
Installers must position the main lock body on the active door leaf and align the strike box directly opposite on the adjacent glass panel or frame. Proper mechanical alignment ensures that the physical locking bolts smoothly engage the strike box cavity without binding or frictional drag during automatic locking sequences.
Power Supply Integration and Battery Installation
The internal drive electronics, visual screen, internal speaker, and touch keypad operate on an autonomous direct current source:
- Primary Power Source: The unit requires 4 × AA alkaline batteries (they are not included) installed into the internal chamber beneath the rear battery cover.
- Cell Compatibility: The manufacturer specifies standard alkaline chemistry; rechargeable and non-alkaline batteries (they are not included) are not recommended.
- Safety Precaution: Never detach the battery cover or remove batteries (they are not included) while the lock is in an active working state.
- Emergency Power Interface: If the internal alkaline batteries (they are not included) fully deplete, the lock features an external 5V DC micro USB emergency power port, allowing transient powering via an external power bank to complete biometric or keypad authorization.
Environmental and Site Installation Parameters
The lock is certified under CE, FCC, and RoHS standards and manufactured in ISO-compliant facilities. To maintain long-term operational integrity, installation sites must conform to the factory environmental ratings:
- Operating Temperature: Rated for functioning across an ambient thermal range of -25°C to 55°C.
- Atmospheric Restrictions: Do not install the lock in environments with corrosive substances, heavy airborne salinity, excessive ambient heat, intense radiation, or localized high magnetic fields.
- Power Management: The unit automatically powers off within 10 seconds without operation to conserve internal cell life.
Initial Setup, Administrator Enrollment, and Factory Reset
Once mechanically secured and energized, initial commissioning must be performed before enrolling general users:
- Default Administrator Verification: Initial access to lock programming requires entering the factory default administrator password: 0123456789. Once verified, the administrator can manage credential storage for up to 100 fingerprint, 100 password, and 100 RFID card slots (1 administrator and 99 standard users, up to 300 credentials total). Keypad password configurations support 6 to 10 digits, backed by random anti-peep coding up to 30 digits total.
- Normal Open Mode Setup: For continuous access during business hours, Normal Open mode can be toggled by rotating the interior thumb-turn knob or by pressing 2 and 8 sequentially following administrator verification. Pressing the * key immediately cancels Normal Open status.
- Hardware Initialization: To execute a factory reset, depress the physical reset button located on the back body of the lock, or navigate through the administrative menu on the visual screen until the internal speaker delivers the audible voice prompt "succeed".
