Fig. 8. The ways to connect detectors to zones. The detector outputs are designated with
letters: A - alarm, T – tamper. R=R1+R2.
5.7.1 End-of-line resistors
The value of R1 and R2 resistors is programmable within the range from 500 Ω to 15 kΩ (the
sum of preset values may not exceed 15 kΩ – see PROGRAMMING manual). The factory preset
values are as follows:
R1 = 1.1 kΩ;
R2 = 1.1 kΩ.
If the resistor value in the keypad or expander is not programmable, in Single EOL
configuration, the 2.2 k Ω resistor is required, and in Double EOL (2EOL) configuration
– two 1.1 k Ω resistors.
5.8 Connecting the sirens
If high-current output is not used, the 2.2 k Ω resistor should be connected between the
output and common terminals.
