Check system’s 120 VAC circuit breaker at the building’s power distribution
box. Remove overlay (Fig. 4 on page 10) and check fuse Fl (Fig. 4). If Fl is
open, contact Simplex for service. Check input wiring at TBl-1 (XMER) and
TBl-2 (XMER).

will be connected to the suppressor, disconnect or combination board, if used).
Remove the resistors and reconnect the zone wiring after testing. If indicators
