Section 1 — General Information
Remote Annunciator Panels
3. Latch Select: The lamps and horn can be selected
to be latched by on-board switch. Unlatched signals
activate the lamp only; the lamp is de-energized if
the fault signal is cleared. Latching provides an
audible signal plus keeps the lamp energized as an
indicator even if the pre-alarm fault has been
cleared.
4. Rearm: The rearm clears the horn but not the
lamps. The lamps are held active by either latch or
fault signal. After rearm, horn is enabled to sound if
another fault occurs.
5. System Ready Lamp: This lamp indicates the
genset is operational. The lamp is energized when-
ever power is applied to the annunciator circuit and
no generator stop signals are present.
6. Line-Power/Gen Power Lamps: This indicates the
position of the transfer switch. When load is trans-
ferred to the genset, the “Generator Power” lamp is
lit and the horn sounds.
7. Horn Switch Off Lamp: This lamp indicates that
power to the horn has been disconnected by a horn
disable switch.

the exist for the following minimum times:
• Not in Auto, Horn Off, 100 seconds.
