Controller Call 4 Zone No Power Supply Unit

The 4 Zone Call Controller is a versatile and efficient emergency call management unit designed to support up to four separate zones. Featuring dedicated RESET and MUTE buttons along with four zonal alarm LEDs, it offers clear status monitoring and control. This controller requires a separate 12V 250mA power supply unit (NC930) for operation and supports the connection of up to two controllers per PSU, allowing the creation of a mini-call system with up to eight zones. Designed for easy installation, it mounts neatly onto a standard 25mm UK double gang back box, making it ideal for centralized fire alarm or emergency call systems.
