The automatic extinguisher control panel is designed in accordance with European standards EN54-2 and EN54-4 Fire Detection and Fire Alarm systems - Control and Indicating Equipment and EN12094-1 Fixed firefighting systems - Components for gas extinguishing systems
Part 1:
Requirements and test methods for electrical automatic control and delay devices.
The control equipment is a combined fire alarm control panel and extinguishing
system and has four detection zones, any or all of which are capable of contributing
to the extinguisher release decision.
Control panels have an integral, mains powered battery charger and power supply
designed in accordance with the requirements of EN54-4.

Conventional Fire Fighting Panel
Key Specifications/Special Features
Four Style B(Class B)Initiating Device Circuits(IDCs)。
All zones accept two-wire smoke detectors and any normally-open contact devices.
One built-in Fire Fighting Ouput.
24-volt operation.
Resettable four-wire smoke detector power@500 mA.
Non-resettable power@500 mA.
One-man walk-test programmable for silent or audible test.
Disable/Enable control per IDC.
Reverse polarity protection
There are 6 buttons on the panel, Emergency evacuation, external muffler, Self-test/Reset, Internal muffler, exhaust fan, Emergency Stop
Control lock allows and disables key function, manual and automatic switching modes
The standby 12V/4.5A power supply is placed at the bottom of the chassis. If the battery polarity is incorrect, the yellow battery fault message is displayed on the panel.
Emergency gas release: Pull out the yellow plastic box panel on the panel, and there is a red button inside. Press the button, the controller will enter the "emergency start" delay state, showing a countdown of 10 seconds, and send a start signal after the countdown is over.
L Controller has 4 independent alarm area (ZONE1-ZONE4), can be connected with multi-line smoke, temperature, manual alarm
Button and other input equipment, can independently complete equipment fault detection and alarm function.
L The controller has three sound and light alarm outputs (SounD1-SOUND3), which can be easily used for external emergency alarm in case of fire
.
L the controller has one 24VDC/1A POWER output (power-24 v,0V) to supply POWER to external devices.
L Controller has 1 way fault, 1 way fire alarm relay output.
L The controller has remote mute, remote alarm test, remote fault test and remote reset functions.
L The controller has remote emergency start, remote emergency stop and remote hand/automatic mode switching functions.
L The controller has cylinder pressure undervoltage signal receiving function and gas release feedback signal receiving function.
L The controller has valve function.
L The controller can set 0-75s delay valve function.
L The controller has the function of manually opening and closing the exhaust fan.
