The plug-in loop driver card provides power for and
handles communications to the addressable devices.
The loop driver card 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
driver card. Each Apollo device has either an XPERT key
(in the detector base) or a Dual-In-Line (DIL) Switch (on
the module) to allow a unique address, in the range 001
to 126, to be selected.
The loop driver card can support class-A and class-
B wiring configurations. Short-circuit isolation
and double address detection are built into the
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.
The fire alarm panel performs a calibration and
contamination check once every 24 hours. If the
detector zero point falls outside of specific limits
or approaches the pre-alarm point, the panel will
indicate a trouble. A calibration is automatically
performed each time an Auto-Learn is performed.
A manual “Calibrate” option is also available on
the configuration menu
