CHAPTER 7: HARMONY ALARMS
This chapter describes the Harmony alarms and what you should do if an alarm occurs.
7.1 INTRODUCTION TO ALARMS
The Harmony provides three alarm levels: high, medium, and low priority.
High Priority These alarms require immediate response.
The alarm signal consists of a red LED indicator and a sound that is either continu­ous or a pattern of three beeps, a pause, and then two more beeps. The display has the message ALARM at the top of the screen.
Medium Priority These alarms require prompt response. The
alarm signal consists of a yellow LED and a sound that repeats a pattern of three beeps. The display has the message ALARM at the top of the screen.
Low Priority These alarms require your awareness. The
alarm signal consists of a yellow LED and a sound that repeats a pattern of two beeps. The display has the message ALARM at the top of the screen.
Some audible alarms are self-cancellable. This means that the alarm sound stops when the cause of the alarm is corrected.
The alarm LED indicators are located on the right side of the keypad, as shown in Figure 7–1.
