Prosafe Trapped Key Interlock Switches Access/Chain Interlocks Specifications Standards Category Approvals Single Dual 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.

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.
