Display and Controls
Alarm LEDs (Red)
For all unit configurations except Master Repeater units, each
alarm LED corresponds to an input and illuminates on alarm
(after the programmable alarm delay expires). For Master
Repeaters, its LEDs illuminate with the corresponding alarm
point from the unit in alarm: ie, Master Repeater alarm 1 will
illuminate when any of points 1, 9, 17 or 25 is in alarm. When a
connected unit goes off-line from the EIA-485 bus, all eight
LEDs flash, indicating a problem.
Normal LED (Green)
When input power is OK, the Normal LED illuminates (solid). If
the RCM8 is running on the NiCad backup battery, the Normal
LED blinks.
Audible Alarm
When any alarm is active, an audible alarm sounds. If alarms are
non-latching (not requiring acknowledgment to reset), the beeper
stops when the alarm situation no longer exists. If the alarm is
latching, the beeper continues to sound until an operator
acknowledges the alarm condition and resets the beeper.
You can disable the audible
beeper by removing the P1
connector on the RCM8
circuit board. See Figure 3
in Chapter 2.
