Total system power and wire length guidelines
The panel can supply up to 1 amp (1,000 mA) in full load alarm condition for
system devices connected to panel terminals 4 (+12V), 7 and 8 (speaker
terminals), 9 (OUT1), 11 (+12V), 24 (2W SMK ZONE 8), and SnapCard
terminals.
For 24-hour backup, the total standby current draw for all devices connected to
panel terminals 4 (+12V), 9 (OUT1), 11 (+12V), 24 (if configured for 2-wire
smoke loop), and SnapCard terminals is limited to 90 mA (during normal standby
condition) using a 4.5 or 5.0 Ah battery, or 190 mA (during normal standby
condition) using a 7.0 Ah battery.
The total system wire length allowed can vary depending on devices powered by
the panel, the wire length between devices and the panel, and the combined wire
length of all devices.
