1.3 Controls and Indicators
Front Panel Membrane User Buttons
Acknowledge
This function, also abbreviated to "ACK", is used to acknowledge an abnormal situation such as an
alarm or trouble condition. The acknowledge function tells the panel that building personnel or
emergency responders are aware of the alarm, trouble, or supervisory condition. Acknowledging the
alarm or trouble condition also normally silences the panel's own sounder.
Alarm Silence
Also known as "audible silence". Depending on the configuration of the alarm system, this function
will either silence the system's notification appliances completely, or will silence only the audible
alarm, with strobe lights continuing to flash. Audible silence allows for easier communication
amongst emergency responders while responding to an alarm. This can also be used during
construction as a means of a preliminary test, before the final full test.
Reset
This resets the panel after an alarm condition. All initiating devices are reset, and the panel is
cleared of any alarm conditions. If an initiating device is still in alarm after the system is reset, such
as a smoke detector continuing to sense smoke, or a manual pull station still in an activated
position, another alarm will be initiated.
LED Indicators
AC Green LED
AC power (green light) when this indicator is lit, power is being provided to the system from the
building's electrical system, and not from the backup battery. When an AC power condition changes,
the Trouble indicator comes on and the AC power indicator goes off and the screen alerts building
personnel of a power failure. If the AC power indicator is lit without any other indicators also lit, then
the system is in a normal condition. If no LEDs are lit, there is no power source feeding the panel.
ALARM Red LED
Alarm (red light) This indicator is lit when an alarm condition exists in the system, initiated by smoke
detectors, heat detectors, sprinkler flow switches, manual pull stations, manual call points, or
otherwise. Along with the indicator on the panel, notification appliances, such as horns and strobes,
are also activated, signaling a need to evacuate to building occupants. In an alarm condition, the fire
alarm panel indicates where the alarm originated. The alarm panel can be reset once the device
which initiated the alarm is reset, such as returning the handle of a manual pull station to its normal
position.
TROUBLE Yellow LED
Trouble/Fault (yellow light) When held steady or flashing, it means that a trouble condition exists on
the panel. Trouble conditions are often activated by a contaminated smoke detector or an electrical
problem within the system. Trouble conditions are also activated by a zone being disabled
(disconnected from the system), a circuit being disabled, low power on the backup battery, the
disabling of a notification appliance, the ground faults, or short or open circuits. The alarm panel's
sounder will activate if a trouble condition exists. In a trouble condition, the panel displays the zone
or devices causing the condition. The "Trouble" indicator goes out automatically when the situation
causing the trouble condition is rectified.
