Model 3100 Series Flame Detector (11/04)

Instruction Manual
(“on” or “off”) of a switch (SW1-SW8).
The first flash pattern indicates the position
of the first switch (SW1), with each consecu-
tive flash indicating the position of the next
switch in order. The flash pattern is as fol-
lows: only one LED “on” indicates a switch
in the “off” position, both LEDs “on” indi-
cates a switch in the “on” position. The po-
sition of SW9 is not indicated. If SW9 is in
the “on” position the detector will power up
in fault mode.
2.6.4 Fault
When the detector has power and is in Fault
Mode LED1 (the left LED when facing the
detector with the configuration switches be-
low the LEDs) will be on for 5 seconds while
the LED2 (the right LED) will be off see
Table B.4 on page 12. The LED will turn
"off" and LED 2 will begin flashing 1/2 sec-
onds "on" and 1/2 second "off" a number of
times. The number of times LED2 flashes
indicates the type of fault. This cycle is re-
peated until the fault is corrected. Only the
highest number fault is indicated. Once a
fault is corrected the next highest level fault
will be indicated until all faults are cured.
Except for fault level 2 and 3, a fire indica-
tion will override a fault indication. The de-
tector is disabled if a fault 2 or 3 is indicated.
2.7 Relay operation (See Figure 2-4)
The Model 3100-01 has two relays, the enhanced
Models 3100-02, -03, -04 and -05 have four relays.
The function of the Fire and Fault Relays is the
same on all models. The Verify Relay and Aux.
Relay is only available on the enhanced models. All
relay connections are made at the connectors lo-
cated on the back of the flame detector module.
2.7.1 Fire Relay
The Fire Relay will energize whenever the
detector declares a fire. Depending on the
configuration setting, the relay will: “Latch-

2.6.2 Normal
In Normal Mode the LEDs will flash briefly
every 8 seconds. Whenever the device is in
any other mode the “flash every 8 seconds”
is suspended until the detector returns to
Normal Mode.
2.6.3 Fire
When any version of the Model 3100 de-
clares a fire, both LEDs will come “on” and
stay “on”. If the detector is set to "Latching"
the LED's will remain "on" and stay "on"
until the detector is powered down. If the
detector is set to "Non-latching" the LED's
will reset to "Normal Mode" when the fire is
no longer being detected. If the Verified Fire
is declared (Verify Fire is only on the En-
hanced Models) the LEDs will blink “off”
briefly every second. If the detector is set to
"Latching" the LED's will remain in this state
until the detector is powered down.
