Date: 2016/12/02
Conventional Fire Alarm System is manual controlled or automatically controlled Fire Security System. There are Fire Indication LEDs, Sounders on the alarm control panel. It is important for fire safety guard to read and understand the meaning of fire indication and sounders.
16 zone FACP (Fire Alarm Control Panel) CK1016 is an example. It has all LED indications and keypad on the panel to supervise all wiring, NAC (Notification Appliance Circuits), troubles and alarm.
AC Power – green or yellow LED
Battery – green or yellow LED
Mute – yellow LED
Silence – yellow LED
Fire Alarm – red LED
Fault – yellow LED
Supervisory – red LED
Activate – red LED
Zone Disabled – yellow LED
Sound Disabled – yellow LED
NAC Fault – yellow LED
Manual – red LED
Automatic – red LED
Sound1 to 4 – red LED or yellow LED
Zone Fire Alarm – red LED

Ground Fault – yellow LED
Status LEDs
AC Power LED
A green LED that remains on while the AC power supply is within correct limits. A yellow LED blinks under Battery powered condition. It turns on steady when Mute key is pressed. If this indicator fails to light under normal conditions, service the system immediately.
Battery LED
A green LED that remains on while the Battery power supply is within correct limits. A yellow LED that blinks is to indicate a low battery or no battery condition on the PANEL. It turns on steady when Mute key is pressed. If this indicator fails to light under normal conditions, service the system immediately.
Mute LED
A yellow LED that turns on to indicate that an Alarm or Fault condition exists in the system, but piezo sounder have been silenced.
Silence LED
A yellow LED that turns on to indicate that an Alarm condition exists in the system, but Notification Appliance Circuits have been silenced.
Fire Alarm LED
A red LED that turn on when a system fire alarm condition is detected.
Fault LED
A yellow LED that turn on to indicate that a system fault or abnormal condition exists and that the fire alarm system may be inoperative. It turns on steady when a signal Silence or Mute key is pressed.
Supervisory LED
A red LED that turn on to indicate the need for action in connection with the supervision or maintenance of sprinklers, extinguishing systems or other protective systems that connected in Supervisory Terminal.
Activate LED
A red LED that flashes when enter the directly activate mode. In this mode, the Notification Appliance Circuits (Sound1-Sound 4 Output) can be activated directly by manual. A red LED that turn on to indicate any of sound1 to sound 4 has been activated.
Zone Disabled LED
A yellow LED that turn on to indicate that one or more alarm zones have been disabled. The disabled zone(s) fault LED will also be on. When enter program mode, a flash LED indicates the program features.
Sound Disabled LED
A yellow LED that turn on to indicate that one or more Notification Appliance Circuits (Sound1-Sound 4 Output) have been disabled. The disabled Sound(s) yellow LED will also be on. When enter program mode, a flash LED indicates the program features.
Manual LED
A red LED that turn on to indicate that the panel is running in manual mode. In manual mode, All Notification Appliance Circuits (Sound1-Sound 4 Output) have been disabled, but Sound1-Sound 4 Output can be activated by manual.
Automatic LED
A green LED that turn on to indicate that the panel is running in automatic mode. In automatic mode, All Notification Appliance Circuits (Sound1-Sound 4 Output) have been enabled that can be activated by Zone alarms.
Zone1-Zone4 activates Sound1.
Zone5-Zone8 activates Sound2.
Zone9-Zone12 activates Sound3.
Zone13-Zone16 activates Sound4. A red LED that turn on to indicate that the corresponding Notification Appliance Circuits (Sound1-Sound 4 Output) is be activated. A yellow LED that turn on to indicate that the corresponding Notification Appliance Circuits (Sound1-Sound 4 Output) have been disabled or has some fault.Red LEDs that blink to indicate that an alarm exists on the corresponding zone. It turns on steady when Mute key is pressed.Yellow LEDs that blink to indicate that a fault or abnormal condition exist on the corresponding zone. It turns on steady when Mute key is pressed.LEDs on Main PCB board:A green LED that remains on while the batteries has been charging by AC power.A yellow LED that remains on while the panel has earth fault.A yellow LED that remains on while the panel has some fault.Normal Mode is the standard mode of operation. In this mode, the panel continuously monitors system status. The Notification Appliance Circuits will be off, all relays are in their normal state and the onboard piezo sounder will be off. 1. Alarms3. System Faults4.3.1 Fire Alarm Response
The control panel will, upon detection of an alarm condition, cause the following:
2. Supervisory Alarms
Higher priority events take precedence over lower priority events. Display and reporting of System Status is done on a priority basis. Priorities are, from highest to lowest:
All alarm and system fault conditions are annunciated on the control panel’s LEDs. The control panel will maintain a ‘last event list’ which will consist of all alarms, supervisory alarms and system faults currently active and not cleared, requiring immediate service. When the system is cleared and restored to normal, the LEDs will be off except for the AC Power LED and Battery LED and status LEDs.
Operation
System Fault LED
Ground Fault LED
Charger LED
Zone 1 through Zone 16 Fault LED
Zone 1 through Zone 16 Alarm LED
Sound1-4 LED
Turn on the system Alarm LED
Blink the Zone Alarm Red LED (? second On, ? second Off)
Turn the Notification Appliance Circuits on
Turn the piezo sounder on steady
Turn on alarm relayThe control panel returns to normal after all alarms have been cleared and a system reset key has been pressed (pull stations have been reset, smoke detectors have reset and no smoke is present, waterflow has stopped). The control panel will perform the following upon restoral of all active alarms:
Fire Alarm Restoral
Turn off the alarm LED
Turn off the Zone Alarm LED
Turn off the Notification Appliance Circuits
Turn off the piezo sounder
Turn off appropriate zone relay output
Turn off alarm relayThese Supervisory zones can be for supervisory in applications where a waterflow sensing device has been employed and the wiring to the waterflow valve and/or a tamper switch is to be monitored. If the tamper switch has been activated (normally open contacts close), a supervisory alarm condition will occur.
When a supervisory condition occurs, the control panel will cause the following:
System Supervisory Condition Response
Turn on the supervisory LED
Pulse system piezo sounders (? second On, ? second Off)
Turn on supervisory relayWhen the supervisory condition has been cleared and the reset key has been pressed, the control panel will perform the following:
System Supervisory Restoral Response
Turn off the supervisory LED
Shut off system piezo sounders
Turn off supervisory relayThe control panel will perform the following upon detection of one or more fault conditions:
Fault Condition Response
Turn on the trouble LED
Blink the Zone fault LED if fault condition is on the zone (? second On, ? second Off)
Activate fault relay
Sound system piezo sounders at a rate of 1? second On, 1? second OffThe control panel performs the following upon restoral of all trouble conditions:
Fault Condition Restoral
Shut off the fault LED
Shut off the zone fault LED(s)
Shut off the piezo sounder
Deactivate the fault relay
Local Sounde
A piezo sounder provides separate and distinct sounds for alarm, trouble and supervisory conditions:
Alarm – pulse ? second On and ? second OFF
Fault – pulse 1? second On and 1? second Off
Supervisory – pulse ? second On and ? second OFF
