Connecting supervised inputs
Connect supervised input switches to INPUT1 and INPUT2, as shown in Figure 8
below.

Nominal resistance values (including any cable resistance) are shown in Table 8
below.

Input function
Input Value [1] State
Fire routing acknowledgement (type 1,
100 seconds)
1 ≤ 220 Ω Short circuit
> 220 Ω to 8 kΩ Active [2]
> 8 kΩ to 10 kΩ Fault [3]
> 10 k Ω to 20 kΩ Standby
> 20 kΩ Open circuit
[1] Values between each state may vary, depending on tolerance.
[2] For EN 54-13 compliance, the active impedance should be i n the range of 220 Ω to 3.9 kΩ.
[3] High impedance fault.

Fault warning output: open circuit supervision ≤ 9 kΩ > 9 kΩ
[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 17.
