Zone Adder Module (Model ZA-42)
Figure 6: ZA-42 Zone Adder Module
Class A / B Selection:
JW2 & JW3 are connected from 1 to 2 for initiating circuit Class B (Style B) operation, and from 2 to 3
for Class A (Style D) operation.
Note:
The Class A/B selection affects all initiating circuits, and must be used with the correct Con
fi
guration DIP switch 9 #6.
P1 & P2:
Connections to P7 & P6 respectively on the main

Relay Modules (Models ARM-4 or ARM-8)
Figure 7: ARM-4 or ARM-8 Relay Adder Module (Zone Operated)
P1:
Connect to P1 on the main
fi
re alarm board.
By the factory setting, the four or eight relays are controlled by initiating circuits 1 to 8 respectively. This is con
fi
gured by
selecting:
JW1:
•
Initiating Circuit #1 controls Relay #1.
JW2
•
: Initiating Circuit #2 controls Relay #2.
JW8:
•
Initiating Circuit #8 controls Relay #8.
Alternately, each relay may be set as a Common Alarm or Common Supervisory Relay by removing the jumper from JW1 to
JW1A, etc. These jumpers have two
positions to select Alarm or
Supervisory each.
JW1A:
•
Alarm or supervisory
control for Relay #1.
JW2A:
•
Alarm or supervisory
control for Relay #2.
JW8A:
•
Alarm or supervisory
control for Relay #8.
Finally, there are jumpers
JW1.2
,
JW2.3
, up to
JW7.8
that allow a relay to
have the same control as an adjacent
relay. For example, starting with the
factory default setting, moving the
jumper from JW2 to JW1.2 will make
both relays 1 & 2 operate with Initiating
Circuit #1.Contact Potter Technical
Support for assistance if required.
