Description
The bolt interlocks are designed to allow access to hazardous areas
when an appropriate key is inserted into the interlock. These bolt
interlocks are manufactured in 316L stainless steel to provide a
rugged, industrial grade method of helping prevent access through
gates.
One advantage of the bolt interlocks is that there is no need to run
power wires to the gate. Power is disconnected by a trapped key
rotary switch on a control panel and the key is then hand-carried to
the gate by the operator.
The Single Bolt interlock (SBL) is designed to be used to access
hazardous areas where partial body exposure is required. The SBL is
not shipped with a key. If two keys are needed for partial body
access, select the Dual Bolt interlock (DBL) that requires both keys
to be trapped to operate. This version of the DBL does not include
the keys.
When whole body access is needed, the DBL, with one primary key
and one secondary trapped key (included) should be used. The
secondary key serves the function of a personnel key. This DBL
allows the operator to carry the personnel key into the hazardous
area. When the operator returns from the hazardous area and
returns the personnel key to the DBL, the locking sequence can be
reversed and the process re-started.
