The Key receptor strips come standard with 10 key positions and 8 key positions. Locking key slots strip lock key tags in place and will only unlock them to authorized users. As such, the system provides the highest level of security and control for those with access to the protected keys and is recommended for those who need a solution that restricts access to each individual key. Dual-colour LED indicators at each key position guide the user to quickly locate keys, and provide clarity as to which keys a user is allowed to remove. Another function of the LEDs is that they illuminate a pathway to the correct return position, should a user place a key set in the wrong place.
