Control Terminal Wiring
ZONES 1-8:
Zones 1-8 are for connection of NO or
NC alarm contacts. These zones require a 2.21K ohm
resistor (P/N 25899) at the end of the loop. Power is
momentarily removed after a [PIN] [System Reset]
during a fire verification. Only zone 1 may be used for
compatible 2-wire smoke detectors (up to 20). Zone
programming is done in address 034 for zones 1-8.
