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
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.
