Connection advice
The unit should be connected to the Honeywell Galaxy
panel as shown in figure 9, RS485A to A1 and RS485B
to B1. Do not use the secondary data line (if your panel
has one – A2/ B2) as it will not work. Ensure that the
GND of the unit is connected to the GND terminal on
the panel.
It is recommended that good quality screened
cable (Belden type, CAT5e or equivalent) is used in all
wiring of this type to avoid interference on the panel's
data bus. A 680Ω resistor should be used at the end
of the 'daisy chain' line of devices in the normal way,
taking care not to exceed the maximum number of
devices allowed on that data line. If the unit is fitted
less than 5m from the alarm panel then an additional
termination resistor is generally not required.
The unit does not have a terminating resistor.
