Introducing NRTL certification to the ICS Interlock System!

Updated: Jun 1, 2022

The new ICS 9 has NRTL Certification and is approved for use throughout the USA. OSHA’s Nationally Recognized Testing Laboratory (NRTL) Program recognizes private sector organizations so they can perform certification for certain products to ensure that they meet the requirements of both the construction and general industry OSHA electrical standards. The interlock has been tested by TÜV SÜD America Inc. to IEC 61010-1 Safety requirements for electrical equipment for measurement, control, and laboratory use. Part 1 General requirements.

The product fulfills the requirements of CAN/CSA C22.2 No. 61010-1:2012, UL 61010-1:2012, and EN 61010-1:2010


The ICS 9 is designed to achieve EN ISO 13849-1 PLe (to achieve performance level ‘e’)

The standard ICS-9 has a deep back box so that contactors can also be added to give interlocked 32A single phase and 3 phase mains supplies. The ICS-9 can be connected to other Lasermet Interlock® controllers to operate as a primary or secondary unit.

Details and Background

The ICS-9 Laser Interlock® Controller is the successor to the highly successful ICS-6 (which it directly replaces).

  • This compact unit can control laser interlocks, magnetic door locks, LED warning signs, and can operate laser shutters. It enables the laser to be powered by controlling the laser safety input. It has feedback monitoring and fault detection. It can be interfaced to Access Control and Fire Detection Systems and it is fitted with an Override to allow controlled access through interlocked doors while also accepting emergency stop inputs. The override is operated either by a push-button (on the inside of a laser-controlled area) or by a keypad-operated override. (e.g. KP-14)

  • The ICS-9 has full start-to-end dual-channel architecture and fault detection to meet the latest safety standards to a much higher level than single-channel systems.

  • It has a simple, easy-to-use control panel and can be connected directly to nine interlocks (or groups of interlocks). The standard ICS-9 has 9 volt-free interlock operator output contacts which may be used for various purposes including:

    • Switching laser power

    • Controlling beam shutters

    • Operating the laser’s interlock input

    • Controlling door locks
