3.5.8 Alarm 1 and 2 Settings
The FP-524D has the ability to set alarm levels that are displayed on the front of the sensor via the LED’s
ALM 1 and ALM 2. These alarm LEDs can be set as latching or non-latching. In non-latching mode, the
LED is deactivated as soon as the sensor alarm condition is cleared. In latching mode, the LED remains active
even after the alarm condition has cleared. Once activated, the LED can only be deactivated by swiping a
magnetic programming tool above the PGM1 or PGM2 mark on the FP-524D face plate.
The alarm LEDs can be configured for ascending or descending mode. In ascending mode the LED will be
activated when the concentration is above the alarm threshold. This is the most common mode of operation
for the FP-524D. The alarm LEDs can also be activated in descending mode. In this mode, the alarm LEDs
will activate when the concentration is below the alarm threshold.
The menu item appears as: “Alarm X Settings”
From the “Alarm X Settings” text scroll, hold the programming magnet over PGM1 or PGM2 until the “▼”
prompt appears and continue to hold the magnet in place for an additional 3-4 seconds (until the display starts
to scroll “Set Level”). The display will then switch to “XXX“(where XXX is the current alarm level in ppm).
Swipe the magnet momentarily over PGM2 to decrease or PGM1 to increase the alarm level until the desired
level is displayed. Hold the magnet over PGM1 or PGM2 for 3 seconds to accept the new value (until the
display starts to scroll “Level Saved”).
The display will scroll “Set Ascending”, and then switch to “Yes” or “No”. “Yes” indicates the LED is in
ascending mode and “No” indicates the LED is in descending mode. Swipe the magnet momentarily over
PGM2 or PGM1 until the correct value is displayed. Hold the magnet over PGM1 or PGM2 for 3 seconds to
accept the new value.
The display will scroll “Set Latching”, and then switch to “Yes” or “No”. “No” indicates the LED is non-
latching and “Yes” indicates the LED is latching. Swipe the magnet momentarily over PGM2 or PGM1 until
the correct value is displayed. Hold the magnet over PGM1 or PGM2 for 3 seconds to accept the new value.
Hold the magnet over PGM1 or PGM2 for 3 seconds to accept the new value (until the display starts to scroll
“Saved”). Move to another menu item by executing a momentary hold, or, return to Normal Operation via
automatic timeout of about 15 seconds (the display will scroll “Alarm X Settings” 4 times and then return to
Normal Operation).
3.5.9 Fault Settings
The FP-524D Fault LED can be configured to change state when the sensor experiences a fault condition. This
LED can be configured as either latching or non-latching. In non-latching mode, the LED is deactivated as
soon as the fault condition is cleared. In latching mode, the LED remains active even after the fault condition
has cleared. Once activated, the LED can only be deactivated by swiping a magnetic programming tool above
the PGM1 or PGM2 mark on the TP-524D face plate.
The menu item appears as: “Fault Settings”
From the “Fault Settings” text scroll, hold the programming magnet over PGM1 or PGM2 until the “▼”
prompt appears and continue to hold the magnet in place for an additional 3-4 seconds. The display will scroll
“Set Latching”, and then switch to “Yes” or “No”.
“No” indicates the relay is non-latching and “Yes”
indicates the relay is latching. Swipe the magnet momentarily over PGM2 or PGM1 until the correct value is
displayed. Hold the magnet over PGM1 or PGM2 for 3 seconds to accept the new value.
