Taking the Siren up the ladder safely, insert the
power cable into the Siren. Wrap the cable around
the cable management guide and push any excess
cable back through the hole, leaving enough slack to
fit the Siren onto the mounting plate. Now slide the
Siren onto the mounting plate.
Head back inside, pull though any excess cable
gently, placing in a safe location, out of the way, so
that it is not a trip hazard. Before finishing
installation, make sure that the power supply is
connected and switched on.
