Description
The access interlocks are designed to allow access to hazardous areas
when an appropriate key is inserted into the interlock. These access
interlocks are manufactured in 316L stainless steel to provide
rugged, industrial grade method of helping prevent access through
gates. They are actuated by either a lever or a rod which is connected
to chain.
One advantage of the access 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 key Access interlock (SAL) and Single-key Chain lock
(SCL) are designed to be used to access hazardous areas where
partial body exposure is required. If two keys are needed for partial
body access, select the dual-key access interlock (DAL) or dual-key
chain lock (DCL) with both keys trapped.
When whole body access is needed, the DAL or DCL, with one key
trapped and one key free should be used. The secondary key serves
the function of a personnel key. The DAL and DCL allow 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 DAL or DCL, the locking sequence can be
reversed and the process restarted.
