2.5.2 Verify Control
The Enhanced Model 3100-02, -03, -04, -
05 and -06 have the Verified Fire function.
The Verify Control switches allow the user
to select the verify level, disable the verify
function, or make the Verify Relay operate
in parallel with the Fire Relay. The verify
function in enabled when the detector de-
clares an alarm. The verify level sets the
degree of certainty required to declare a veri-
fied fire. The lowest level (1) is the lowest
certainty (fastest) and the highest level (6) is
the greatest certainty (slowest) of a fire. The
verify function enables an algorithm which
evaluates the fire signature over time to de-
termine the degree of certainty. When the
degree of certainty exceeds the level set by
the configuration switches a Verified Fire is
declared and the Verify Relay is energized.
Switches 3, 4, and 5 control the verify func-
tion.
The factory default is verify disabled
and set to level 0. (SW3, SW4 and SW5 are
off.)
2.5.3 Latching Control
The latching controls allow the detector or
individual relay outputs to be set to “Latch-
ing” or “Fire Following”. “Latching” causes
the relay to stay energized until power is re-
moved from the detector. “Non-latching” al-
lows the relay to reset (de-energize) when a
flame is not present for a short period of time.
For the detector to be set to "Non-latching"
both Fire Output and Verify Output must be
set to "Non-latching". If either the fire out-
put or the verify output is set to "Latching"
then the detector will be set to "Latching".
When the detector is set to "Latching" the
LED's will indicate an alarm until the device
is reset regardless of the fire or verify relay
output settings.
The Verify Relay is automatically configured
as “Latching” if the Fire Relay is set to “Latch-
ing”. SW6 sets the Fire Relay Output, SW7
sets the Verify Relay Output and SW8 sets
the Detector Mode. To set the detector to
"Non-latching", SW6, SW7 and SW8 must
be set to "Non-latching.
The factory defaults
are “Latching” (SW6 and SW7 are off.)
2.5.4 Other Configuration Switches
The last configuration switch (SW9) must be
in the off position.
The factory default set-
ting is off.
2.6 LED operation (See Figure 2-3)
The status of all versions of the flame detectors can
be determined from the LEDs located behind the
lens on the front of the detector. The LEDs will
flash at intervals or remain on to indicate the detec-
tors status. (Fault Mode, Normal Mode, Alarm
Mode, Verified Fire Mode, and on power up the
Configuration Settings).

2.6.1 Power Up
At power up all versions of the flame detec-
tor will begin flashing the LEDs. The LEDs
will flash 8 consecutive patterns which indi-
cates the positions of the configuration
switches. Each pattern indicates the position
