Outstations
Each Outstation has 5 input channels. Up to 125 Outstations may be connected to the EMS-OS,
totalling up to 625 zones. See
8 Outstation Dip Switch Address Sheet

Outstation Panel
Install each Outstation as follows:
1.
Mount the enclosure in a suitable location.
It may be necessary to remove the PCB
from the enclosure temporarily whilst
mounting the enclosure and making
required cable entries. The PCB should be
handled with care and stored in a safe
environment whilst it is out of the
enclosure.
2.
Terminate the power & data bus cable
(RS485) into the top left terminals of the
outstation PCB (
).
For the first outstation, power & data into
the outstation terminals will be fed from
the outgoing terminals of the interface
board of the master panel.
Power and data for the next outstation will
be fed from the outgoing terminals of the
preceding outstation on the top right of the
outstation PCB.
3.
Sensor connections are as per the
instructions for the master panel
(
).
4.
Address the outstation using the DIP switch
on the PCB. The master panel will have
either 1 or 2 interface boards, which will
occupy either address 1, or addresses 1 and
2.
5.
Outstations should be addressed
sequentially, so the first outstation will be
either address 2, or address 3, depending
on the variant of master panel.
6.
If the 12/24v output is to be used,
complete necessary connections, and
ensure the correct voltage is selected. OC
output is for Aqualeak engineer use.
7.
Reinstate the lid.
