Description
STROBE Installation
(Factory setting depends on
whether a strobe is supplied
with the Beacon 410.)
If set to STROBE IS INSTALLED, the strobe circuitry is functional
and items in the Configuration Menu that apply to the strobe
operation become active.
If set to NO STROBE INSTALLED, the strobe circuitry does not
function and items in the Configuration Menu that apply to the
strobe operation do not appear.
NORMAL RELAY STATES
(NORM DE-ENERGIZED)
If set to NORM DE-ENERGIZED, the gas alarm relays are de-
energized in normal operation and energize when the appropriate
alarm circuit is activated. The NO (normally open) relay contacts
are open during non-alarm operation and close when the
appropriate alarm condition occurs. The NC (normally closed)
relay contacts are closed during non-alarm operation and open
when the appropriate alarm condition occurs.
If set to NORMALLY ENERGIZED, the gas alarm relays are
energized in normal operation and de-energize when the
appropriate alarm circuit is activated. The NO (normally open)
relay contacts are closed during non-alarm operation and open
when the appropriate alarm condition occurs. The NC (normally
closed) relay contacts are open during non-alarm operation and
close when the appropriate alarm condition occurs.
NOTE: The fail relay is factory set as normally energized and is
not field adjustable.
