Notes:
(1).
The detector offers four (4) sensitivity settings. The settings refer to the n-Heptane fore of
33 cm-sq.
(2).
When an Alarm (Detection) level condition is encountered, the detector delays the
execution of the Alarm output relay by the specified period of time. The detector will then,
additionally, evaluate the fire condition during the specified Alarm Delay Time. If the Alarm
level is still present, the Alarm outputs will be activated. If this condition no longer exists,
the detector will return to its standby state. The LED will indicate warning level during the
delay time only if the fire condition exists.
(3)
The detector has a selectable latched alarm output capability, which operates according to
the selectable function. If selected, upon the detection of a fire, the detection signal is
latched until manually reset (disconnecting the power supply or performing a manual BIT).
