2.1 Timer Reset Panel BR-530, BR-550
The Timer Reset Panel BR-530 is installed on the bridge, and the Watertight Timer
Reset Panel BR-550 is installed on the wing when it is necessary to have a unit there.
A total of six can Timer Reset Panels can be installed.
If the RESET button is pressed within the selected watch time interval, the watch timer
is reset. If operation on the bridge is not confirmed within the time interval, the ALARM
LED flashes (in yellow) every second for 15 seconds after the selected time interval
ends. The ALARM LED flashes an additional 15 seconds after the PREWARNING
phase ends, accompanied by a 15-second audible alarm. Reset can be done at the
PREWARNING and 1st stage.
You can reset the watch alarm at the 1st stage (before the alarm is sent to the next
stage) with the RESET button on the Timer Reset Panel. If the alarm is sent to the 2nd
or 3rd stage, the alarm cannot be stopped from the Timer Reset Panel. To acknowl-
edge the alarm from the 2nd or 3rd stage, use the RESET key on the Main Alarm Pan-
el.
The RESET LED lights (in green) continuously when the unit is powered.
Note 1: Press the RESET button with a touch-and-release action to reset the watch
timer. The watch timer is not reset if the button is pressed and held.
Note 2: When the RESET button is pressed and held, the connection between the
Processor Unit, Cabin Panel and Timer Reset Panel is checked. The buzzer sounds
when the test is started. See section 3.4.
