Mechanical installation
Refer to “Inside the detector” on page 9 for conduit, pipe interface information, and
mounting hole locations.
The detector is connected to the installed sampling pipework and fixed to the mounting
surface using three screws of a type appropriate to the mounting surface. Ensure that
the sampling and exhaust pipes are securely seated in the pipe ports before securing. If
using a piped exhaust connection, be sure that the sampling and exhaust pipe are fitted
into the relevant port as shown in “Inside the detector” on page 9.
Electrical installation
In keeping with good wiring practice, keep cables and individual stripped conductors as
short as possible while allowing stress-relieving cable forming.
Power cables should be current-rated at 1 A or greater. Signal cable should be 120 Ω or
less twisted pair.
Figure 9 on page 22 shows the terminal block connections that connect the ReadySET
detector to other electronic components. It is recommended that all connection wires be
marked with suitable identification labels or colored rings to aid in the connection
process.
