FSL wiring (DEOL)
Enables individual monitoring of a wire tamper (see
Installation Instructions).
Anti-masking wiring:
If the sensor has the anti-mask attribute, three resistors can
monitor all states (OK, alarm, tamper, masked). The zone
can be programmed just like any other zone (e.g. "Normal
Alarm"), but it must be given the "Masking" attribute.
Important: For wiring examples, see the Installation
Instructions.
3.) Bus input
Normally an 8 x 0.22mm² alarm cable is used. Use
screened cables in areas with interference frequencies (see
also Installation Instructions).
Important: The maximum distance to the furthest extension
must not exceed 1km.
Important: The voltage supply on the extensions must not
fall below 10.5V DC (recommendation: min. 12V). If the
voltage is too low, duplicate the voltage leads with
remaining cables or use an additional voltage supply.
The first extension to the bus is connected to the alarm
centre via the NODE NETWORK IN connector (bus input).
Each successive extension is connected to NODE
NETWORK OUT (bus output) of the previous extension.
4.) AUX error LED
Lights when the fuse blows.
5.) AUX connector
Additional voltage connector for supplying external sensors
and outputs.
6.) Power LED:
Blinkt, wenn die Kommunikation über den Bus gestört ist.
7.) Operating panel error
Lights when the fuse blows.
8.) Connecting operating panels (optional)
The voltage supply on the operating panels must not fall
below 10.5V DC (recommendation: min. 12V). If the voltage
is too low, duplicate the voltage leads with remaining cables
or use an additional voltage supply.
