The plug-in loop driver card provides power for and handles communications to the addressable devices. The loop controller continuously checks the analogue values of all sensors and displays this value on the control panel as a percentage of the alarm threshold value. Both the alarm and pre-alarm threshold levels can be adjusted from the control panel if required. Up to 126 devices can be connected to a single loop controller. Each Hochiki device has either a Dual-In-Line (DIL) Switch on the device or is programmed using a special tool to allow a unique address, in the range 001 to 126, to be selected. The loop controller can support class-A and class- B wiring configurations. Short-circuit isolation and double address detection are built into this module. The AUTO-LEARN facility provided in the ZX series control panels saves considerable time and effort when installing a new loop or when changing sensor configuration. It allows the system to learn for itself what devices have been installed on the loop.
