Caution: A nuisance alarm will result if the external
temperature sensor installation status is programmed
to “F In” (installed) and an external temperature
sensor is not installed.
The external temperature sensor installation status can be
programmed to “F In” (installed) or “F --“(not installed), depending
on whether an external temperature sensor is installed.
Programming the installation status requires the use of the jumper.
To program the external temperature sensor installation status,
follow these steps:
1.
Open the detector enclosure and move the service jumper to the
“ON” position.
2.
Install the jumper on the jumper pins (labeled “SET1”) located
below the rotary switch on the front panel-mounted circuit
board.
3.
Set the rotary selector switch to position “5”. Press the “UP” or
“DOWN” button until the display reads “F In” (installed) or “F
--” (not installed).
4.
Press and hold the “ENTER” button for at least 2 seconds. The
new external temperature sensor installation status is now
programmed.
5.
Remove the jumper and return the rotary selector switch to the
desired position.
6.
Be sure the external temperature reading is within the high
and low temperature set points
, then move the service jumper
to the “OFF” position and close the detector enclosure.
