Lightsys LCD Keypad

Product Description

The Lightsys LCD Keypad is a graphic LCD keypad interface designed for controlling and interacting with a LightSYS or ProSYS security alarm system. It acts as the main user interface for arming, disarming, monitoring, and configuring the alarm system.

 Core Functions

• LCD Display: Shows system status, zone conditions, time/date, alerts, and event information on a clear screen.

• User Controls: Numeric and function keys let users arm/disarm the system, bypass zones, view logs, and navigate menus.

• Backlit Keys: Illuminated keypad supports use in low-light environments.

• Proximity Support: Some models include a proximity reader that lets users arm/disarm quickly with a tag held near the unit.

• Emergency Keys: Dedicated panic, fire, and medical buttons (on certain versions) for rapid alerts.

• Tamper Protection: Detects and signals if someone tries to access or remove the keypad without authorization.

• User Code Management: Supports multiple access codes for different users.

 How It Works

Installed typically on a wall near an entry point, the keypad connects by a 4-wire bus to the main alarm panel (up to ~300 m away) and communicates system status and commands between the user and control panel.

 Typical Uses

• Residential Security: Easily arm or disarm a home’s alarm system.

• Commercial Properties: Control access and monitor multiple security zones.

• Enterprise / Industrial: Manage larger setups with partitioned zones and more advanced options.
