System Description

INTER-CONNECTION & STRUCTURE (CONTINUED)
The relay LEDs simply follow the zone LEDs in the same order that they occur in the
modules. E.g. a system with three 8 Zone Modules and two 8 Relay Modules would require
3 Display bds. Relay 1 would be annunciated on the 25th row of LEDs and the last 8 rows
would be unused as shown in Fig 2.3.3.
Mapping zones and relays to LEDs in other patterns is programmable.
