Prosafe Trapped Key Interlock Switches

Access/Chain Interlocks

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.
