A maximum of 1,500 meters (5,000 feet) of 18 AWG (0.82mm) wire can be used,
(maximum resistance between detectors 50 Ohm). The units are interconnected by
wiring all the terminals marked 1 together, and all the terminals marked 2 together
(as in figure 2 before screwing to ceiling). Draught from wiring openings, conduit, or
mounting boxes/holes, may blow smoke away from the sending chamber, making it
insensitive. It is essential that all such openings be closed by silicone sealant or
similar.
After wiring together the interconnect smoke detectors, test the first unit by
pressing the test button. All the detectors should alarm and the test button on the
first unit will flash about once a second. Check all the other units similarly.
