The Model AM-KP keypad is designed for use with Linear's access control systems. The keypad is housed in a rugged cast aluminum enclosure. The die-cast keys have bright, easy-to-read yellow graphics. Each key has a positive tactile click feel when pressed. An internal sounder signals when a key is pressed. The keypad can be mounted to a pedestal or directly to a wall. A keylock secures the keypad to the mounting backplate. An incandescent panel lamp lights the keypad for nighttime use. Red, green and yellow indicators show power, access and lockout conditions. The AM-KP is normally powered from the control, or it can be powered locally from a 12 VDC power supply. Robust static and lightning protection circuits safeguard the keypad's electronics.
