14 Conventional Products—6424 Projected Beam Type Smoke Detector
When installing the beam smoke detector in applications where the
flexible conduit will be used (all Canadian applications), the Beam
Mounting Bracket (BMB) kit must be installed with the cable before
wiring the unit, as per the instructions supplied with the kit. For
applications that require the flexible conduit to be mounted to the
beam smoke detector, the model BMB kit can be ordered separately.
The BMB kit is included with the Canadian model 6424A.
In those applications where the model BMB kit is not used, the
two connectors with attached cable (6 conductor for the transmitter and
16 conductor for the receiver) can be wired before the detector is mounted.
1.
Remove the precut insulation from the conductor to be connected.
2.
Use a wire nut to connect the detector wire to the field wire.
If the insulation has been removed from any unused conductors, make
sure they are terminated properly to avoid short circuits.
3.
Wire the transmitter in either of two ways.
●
Use a connecting pair of wire to permanently connect the
transmitter to the receiver. The transmitter receives its power
along with communication for the alignment aid through the
connecting pair of wires (Figure 8). Temporary wiring can be
installed for the communication needed for transmitter alignment
aid.
●
Use a remote power source to power the transmitter as an
alternative wiring configuration. Make sure the remote power
source complies with all codes and directives of the authority
having jurisdiction (Figure 9).
