Step 4: Connecting Relay Detectors
Wired non-bus detectors (“relay detectors”) can be connected to the system the
following ways:
• Connect relay detector(s) directly at the zone input terminals (Z1—Z8) on the
terminal block of the main panel PCB. See Main Panel Wiring Diagram, page 25.
• Connect multiple relay detectors onto 8-Zone Expanders and 16-Zone
Expanders (see the illustration below)
• Connect relay detector(s) onto RISCO bus lines, each using a dedicated Single
Zone Expander (see the illustration below)
• Connect a single relay detector directly onto bus devices which support an
input zone. For the Elegant keypad, connect a relay detector to ZONE IN and
ZONE COM terminals, and for the iWISE Bus detector connect to Z1 and
COM terminals.
