Inputs - Bosch FPC-500-2 Installation Manual

20 en | Installation
Notice!
The screw terminals are designed for a cable diameter of
0.8 mm and for cable cross sections of up to 1.5 mm
The fire panel is designed for unshielded cable. If you do use
shielded cable, only connect the cable shielding to the earth
bar on one side above the power supply unit.
Terminal resistances
The zones of the fire panels must be terminated. Use either
resistors or in case of EN 54-13 (BOSEC certificate TCC 2 - 977)
the EOL modules.
Notice!
Only use resistors with a maximum 1% tolerance.
The 3.9 kOhm resistors are supplied.

Inputs

The fire panel offers two control inputs. You can assign different
functions to these depending on programming (see Configuring
Inputs, page 47).
The connection terminals IN1 and IN2 are available.
Notice!
Note that the maximum line resistance for inputs is 22.5 ohm.
Use 820 Ohm ±5% resistors for the alarm resistance (not
included in scope of delivery).
