RTBC-FS is a power connection kit with an
integral line-sensing thermostat which is used
to monitor the temperature of the fire sprinkler
branch lines for compliance with IEEE 515.1.
The NEMA 4X power connection enclosure is
constructed of corrosion resistant Ryton®, that
features an oblique-sided box to allow easy access
to terminal block and thermostat settings.
The enclosure includes a 3/4" opening on the
side for customer provided conduit hub. The
RTBC-FS base features a waterproof cableway
for the heating cable and capillary to enter
the enclosure from underneath to protect the
cables and thermostat from damage. The base
includes a stainless steel tie down to mounting
tab to strap the kit to the fire sprinkler piping
with a stainless steel pipe strap (PS). Inside the
enclosure is a three position terminal block for
connecting the line voltage and heating cable
together and the line-sensing thermostat that
includes a dial temperature control knob. The
RTBC-FS lid is sealed with a gasket and screws
on each corner.
