Ansul INERGEN User Manual

Description
The pull box on an INERGEN
™
system is used to provide
mechanical release of the system from a manually operat-
ed remote station. Two types of pull boxes are available.
The latched door type has a solid cast brass door which
must be opened to reach the pull handle. The second type
has a break glass window and a spring mounted handle
which rotates forward for use when the glass is broken. A
3/8 in. female NPT opening is provided at the back of each
enclosure for connection of the cable housing. Both types
are painted red.
A pulley elbow may be attached directly to the back of the
pull box, if necessary, to provide immediate changes in pull
cable direction. With this option, the pull box can be
extended an additional 3 1/2 in. (8.9 cm) from the mounting
surface by using support legs attached to the back of the
pull box (one set for latched door type, two sets for break-
glass type).
