Page 3: Generally
Device operators of must announce all changes and modifications of the monitored and protected device, any object that could influence the efficiency of the LES-RACK-M1 fire fighting system (e.g. shadowing of extinguishing nozzle when installing new equipment, adding or making new ventilation holes in the box.

DESCRIPTION Technical parameters Table No. 1 : Basic LES-RACK-M1 parameters: Value: Output voltage the AC network 100-240 VAC Frequency 50-60 Hz Current at 230V AC 0.9 A Current peak 70 A Efficiency Current leakage at 230V AC <1mA Input-output insulation voltage...
Page 6  Pressure switch (9) for inspecting the pressure on the pump output.  Smoke sensor (10) built-in to the left rear of the tank. Air, with combustion products are sucked by the radial ventilator (11) from the monitored space through the hole in the rear wall of the box. Using a system of curtains and partition walls (15) is is directed to the smoke sensor.
Page 7: Control - Activation
Control – activation Before activating and commissioning fill the tank with extinguishing agent or check the extinguishing agent top it up, if necessary. The equipment can be controlled by elements on the front panel or remotely by inputs on the rear panel.
Page 8: Extinguishing
Activation The signal to activate “Extinguishing ”can be done in several ways i.e.: - by the LES-RACK-M1 internal sensor - by the external manual button by a signal from the external sensors by a command through the network EXTINGUISHING...

VALVE After the extinguishing agent is discharged, the pump and the valve are disconnected. PUMP The extinguishing ends. For information about the EXTINGUISHING extinguishing, the extinguishing signal lamp continues to shine and because the system has no extinguishing FAULT SYSTEM agent, a system error is activated Termination After extinguishing , the smoke sensor is activated and...
Page 10 Fig. No. 4  Relay outputs. LES-RACK-M1 has 4 relay outputs with one switching contact. Individual relays switching during extinguishing can be user adjusted. The software can be set so that these relays also react in the “TEST ”mode.
Page 11: Signalling
 The external horn provides an acoustic signal in other premises away from the monitored space. The external horn is activated together with the extinguishing command. It can be disconnected by the “MUTE ”button on the LES-RACK-M1 front panel. The horn supply is 12V DC, maximum current 150 mA ...

Page 13: General Safety Provisions
General safety provisions Activation of the LES-RACK-M1 fire extinguisher may create risks for the user because of the natural form of the extinguishing agent or from decomposition products from the contact of the extinguishing agent with the fire or hot surfaces. The equipment user must prevent any affect on the operators by the extinguishing agent, as well as decomposition products, mainly by regular training.
