Figure 20 - Wiring the I/O line as an input
The diagram above illustrates a line wired as an input. The EOL resistor will allow the control panel to
supervise the wiring, and the resistor connected in series to the activation contact will allow it to
discriminate between an activation signal and short-circuit.
Figure 21 - Connecting 4-20 mA gas detectors
The diagram above illustrates a I/O line wired as a 4-20mA gas input, this wiring method allows the line to
interface with a 4-20mA gas detector.
The example shows a gas detector from “industrial” series, “-42” version.
Note:
In order to validate the IMQ-SECURITY SYSTEMS certification, this output should not be used as a type C, E
or J output (EN 54-1), and must not be used to command Fire-alarm or Fault transmission devices.
6.5.3 Wiring
1. Use 2 pole cable with Fire code compliant flame class.
Note:
In order to validate the IMQ-SECURITY SYSTEMS certification:
the total number of fire detectors and/or manual call points connected to a zone using the split method
(terminals + with - and I/O with -), must not exceed 30 units;
t
he maximum wire length must not exceed 3000m and the wire resistance must not exceed 100 ohm.
