COMPONENT DESCRIPTIONS
PROTECTION PANEL
The Protection Panel is located in the operator’s area and displays the current system
status. The Protection Panel contains “SYSTEM OK”, fire “ALARM” and “TROUBLE” lamps,
the audio alarm, the “TEST/RESET” switch, and the “ALARM SILENCE” switch.
The “SYSTEM OK” lamp indicates power is on to the system and that there are no
trouble conditions present. The “TROUBLE” lamp blinks if there is a fault in the detection
circuitry and illuminates solid if there is a fault in the extinguishing circuitry. When the
“TROUBLE” lamp is on, the “SYSTEM OK” lamp will be off and the audible alarm will sound
intermittently. The “SYSTEM OK” lamp will flash when the system is low on battery power.
Depressing the “TEST/RESET” switch tests the Protection Panel’s lamps and audio alarm. The
“ALARM SILENCE“ switch will disable the audio alarm.
When a fire detector automatically detects a fire, the fire “ALARM” lamp and audio alarm
activate. When the Manual Activation Switch is activated, the fire “ALARM” lamp blinks and the
audio alarm activates. The lamp will remain blinking until power is cycled to the system.
The engine shutdown output is a normally open contact (1 Amp maximum) which shorts
to ground 15 seconds after fire and/or significant gas leak detection. The “DELAY ENGINE
STOP” will be illuminated immediately following detection. Pressing the “DELAY ENGINE
STOP” will delay engine shutdown (and extinguisher discharge with fire detection only) an extra
15 seconds. The additional delay will be indicated by a flashing “DELAY ENGINE STOP”.
The Protection Panel also has other features which can be enabled via internal
configuration switches.
