DSC LCD-4501 MAXSYS Programmable Message LCD Keypad

Put clear, actionable security information at your users’ fingertips with the DSC LCD-4501 MAXSYS programmable message LCD keypad. Designed as a professional MAXSYS security keypad for commercial and institutional alarm systems, the LCD-4501 displays plain-language status, trouble conditions and event buffer messages on a large 2-line, 32-character backlit display, reducing confusion and improving response times. It connects to PC4010/4020 control panels via the 4-wire Combus, which both powers the keypad and provides a supervised communications channel, and supports up to 16 keypads for scalable monitoring across multi-door or multi-zone sites. Five programmable function keys and four keypad-activated alarms (Panic, Auxiliary, Fire and Duress) let operators trigger the right action quickly while recorded event logs aid incident review. Rugged, tamper-supervised construction and adjustable backlight/contrast make it suitable for security, surveillance, access control and alarm monitoring applications.
