DIP Switch Settings
When set from the factory (Figure 50), switches 1, 5, and 8 are in the On (Closed) positions. Switch 2, 3, 4, 6, 7 are
in the Off (Open) position. This should be considered the default positions and should not be changed.
Figure 50 - DIP Switch
• Each unit has a unique address based on the DIP switch 1-4 settings, 15 units max on a network.
• If address is 0 (all switches off), the unit will not accept or send any network traffic.
• The unit that has switch 5 set to on will be the “master” and will be in charge of polling all the units below it and
waiting for a reply. The lack of 3 replies in a row will cause an “interlock network supervision fault.” All units will
be polled in a burst every 3 seconds.
• For all non-master units, the lack of being polled for 10 seconds will cause an “interlock network supervision
fault.”
• Any unit detecting a fire condition will broadcast the notification once every second for as long as the condition
persists.
• When the Fire condition is cleared, 10 notifications will be sent, one every second.
• Any unit detecting a supervisory fault will broadcast the notification every 2 seconds until the condition is
cleared.
• When the supervisory fault condition is cleared, 10 notifications will be sent, one every 2 seconds.

Setting switch 8 to its On (Closed) position connects a 120 Ohm terminating resistor to the interlock network.
This switch must be On if this unit is at either physical end of the interlock network cable. Otherwise, it must be
Off (Open).
