10 Front Panel Controls Audible Alarm The audible alarm indicates alarm conditions. The audible alarm sounds continually when the room pressure is in an alarm condition. When the audible alarm is configured for alarm follow operation, the alarm continues to sound until the MUTE key is pressed or the room pressure returns to normal. When the audible alarm is configured for alarm latch operation, the audible alarm remains on until the MUTE key is pressed or the room pressure returns to normal and the RESET key is pressed. The audible alarm tone will beep on and off whenever an emergency condition has been annuciated. This will continue until the emergency condition has been terminated. SETBACK key The SETBACK key is used for in-house testing and has no function in the field. EMERGENCY Key The red EMERGENCY key is used to initiate the emergency mode. In this mode, the room is controlled at either maximum negative or maximum positive pressure, depending on the setpoint. In emergency mode, a controller with a positive control setpoint will open the supply or will close the exhaust, depending on what the SUREFLOW is controlling. Conversely, a controller with a negative control setpoint will close the supply or will open the exhaust, depending on what the SUREFLOW is controlling. The display will flash EMERGENCY, the red Alarm light will flash on and off, and the audible alarm will sound on and off. If the EMERGENCY key or the RESET key is pressed during an emergency condition, the unit returns to normal operation. TEST Key The TEST key is used to initiate an instrument self-test. A test sequence is started when the TEST key is pressed. The sequence displays current information including the software version and various setpoints, and tests the display, indicator lights, audible alarm, and internal electronics. RESET Key The RESET key is used to reset the Alarm light, the alarm contacts, and the audible alarm. If the alarms are in the latched mode, the Alarm light, alarm contacts or audible alarm are reset when the room pressure has returned to normal and the RESET key has been pressed. The RESET key is capable of taking the unit out of an emergency condition and is also used to reset error messages. See the troubleshooting guide in Chapter 11 for details.
