3.0 Wiring
Apply power only after all connections are
made and inspected.
Install these detectors according to the
National Electrical Code, NFPA-70.
Table 7 is based on one set (transmitter and receiver)
connected to the same wire run from the power source.
When installing two or more sets on one wire run,
calculate the maximum length by dividing the
maximum listed wire length by the number of sets
installed.
Connect the transmitters and receivers to a UL Listed
power supply or control panel capable of providing
standby power for at least 4 hours.
Test this system at least once a week to ensure proper
operation.
