2.
It is recommended that you use an end-of-line resistor at the far end of each
hardwired zone (16 x 2.2K resistors are supplied).
3.
In the LightSYS you have the ability to define separately the end-of-line resistance of
the zones on the main unit and of the wired zones for each eight-unit expander block
(Quick key
). Selection is done by the software with the following available
options:

Wiring Auxiliary Devices
Use the
Auxiliary Power
AUX (+) COM (-)
terminals to power PIRs, glass-break detectors
(4-wire types), smoke detectors, audio switches, photoelectric systems and/or any device
that requires a 12V DC power supply.
The total power from the
AUX
terminals should not exceed 800 mA.
Notes:
If the auxiliary outputs are overloaded (exceed 800mA) and are shut down, you must
disconnect all loads from the outputs for a period of at least 10 seconds before you
reconnect any load to the auxiliary outputs.
LightSYS supports 4-wire smoke detectors. To connect a 4-wire smoke detector or
device that requires resetting after an alarm condition, connect the auxiliary power
AUX and output terminals. Use a power supervision relay to supervise the 4-wire
smoke detectors. Loss of power to the detector(s) de-energizes the relay, causing a
break in the zone wiring and a “Fire Fault” message at the panel. Remember to define
the Output as Switched Auxiliary.
In addition, when connecting a 4-wire smoke detector, observe the wiring guidelines
mentioned in the previous sections, along with any local requirements applicable to
smoke detectors, as per the following diagram:
