Safety switches should never be defeated or bypassed. It is imperative that all steps are taken to
ensure that any spare actuators are made unavailable, such that they cannot be used to defeat the
switch or reduce the protection offered by the system in any way.

Concept
The Laser Jailer system uses laser detecting tiles which are available in a range of sizes and are fitted
to the laser side of the enclosure. The tiles are electrically interconnected in series.
The tiles are wired to a monitoring and detection circuit board which is fitted inside a Interlock
Control System (ICS).
The ICS forms the heart of a laser interlock and apart from monitoring the Laser Jailer tiles also
monitors door contacts, emergency stop buttons etc. and provides control of illuminated signage,
override facility, door locking and so on. The ICS is usually connected to the interlock connector on
the laser, or to a beam shutter, so that the ICS can disable the laser beam if the enclosure is
breached.
In the case of Laser Jailer, if a powerful laser beam misses its target and hits a detection tile on the
enclosure wall, it is detected by the monitoring circuit, which in turn trips the ICS which disables the
laser beam.
The monitoring and detection circuit memorises such an event and prevents the system from being
re-armed, even if the power is cycled, until the damaged tile is replaced.
Lasermet provides a full range of laser interlock equipment including control systems, interlock
switches, illuminated warning signs, laser shutters, door locks, external power supplies etc. which
can be connected to provide a complete laser interlock system. Full support, design and installation
is available from Lasermet, please contact us for any queries. Contact details are given at the end of
this manual.
