Set this switch to Closed (On) if this unit has the highest address on the interlock network. Otherwise, this

switch must be Open (Off)

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