Sounders connected to the circuits must be polarized, i.e. fitted with diodes so
that they operate with power in one polarity direction, and not in the reverse
direction.
The sounder lines are fused at 1 A each, and sounders 1, 2, 3, and 4 are fused
by F8, F7, F3, and F2 respectively.
See Figure 45 on page 62. The common fire and common fault relay outputs
provide voltage-free contacts, which can be set to be either normally open (NO,
closing on alarm), or normally closed (NC, opening on alarm). The NO or NC
settings are done in software in the Setup menu.
The common fire relay changes state on any fire alarm, and the common fault
relay changes state on any fault alarm. Relays restore when the panel is reset.
