Connecting supervised inputs
Connect supervised input switches to INPUT1 and INPUT2, as shown in Figure 8
below.
Figure 8: Connecting supervised inputs
Nominal resistance values (including any cable resistance) are shown in Table 9
below.
Table 9: Nominal resistance values for supervised inputs
Input function Input Value [1] State
Fire routing acknowledgement (type 1,
100 seconds) 1 ≤ 220 Ω Short circuit
> 220 Ω to 8 k Ω Active [2]
> 8 k Ω to 10 k Ω Fault [3]
> 10 k Ω to 20 k Ω Standby
> 20 k Ω Open circuit
[1] Values between each state may vary, depending on tolerance.
[2] For EN 54-13 compliance, the active impedance should be in the range of 220
Ω to 3.9 k Ω .
[3] High impedance fault.

Input function Standby Fault (open)
Fault warning output: open circuit supervision ≤ 9 k Ω > 9 k Ω
[1] For the open circuit supervision of the fault warning output with the input, a 2010-FS EOL
board must be installed. See “Connecting the fault warning output” on page 18.
