
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

The manual activation button activates extinguishing from other places than the monitored space.
The integrity of manual activation button is continuously monitored.
The connection diagram for the door contact is in Fig. No.:6
The resistance values in the diagram are as follows:
Rp: 1K8 Ohm, 0.1 W
Rs: 470 Ohm, 0.1 W

External sensors. The extinguishing process can be remotely activated by signals for the other
detectors or other extinguishing equipment. The inputs marked with the text “Sensor 1 ”to “Sensor 3 ”
are for this.
The sensitivity of the external sensors circuits is also
continuously monitored.
The connection diagram for the external sensors is in Fig.
No.:7
The resistance values in the diagram are as follows:
Rp: 1K8 Ohm, 0.1 W
Rs: 470 Ohm, 0.1 W

External temperature sensor - installed in the space where the temperature must be monitored. The
temperature sensor checks the temperature in the monitored space. If the default temperature limits
are exceeded, the user selected relay is activated.
Signalling
Local signalling is by multi-coloured LED diodes under the labels of the function description of the
respective device or the system state. Individual statuses are described in Table No. 5.
The meaning of the letters in the “colour ”column are as follows:
R - red
G - green
Y - yellow
B - blue
