Safety Warnings
The technician attempting to repair a Laser Jailer system must familiarise himself with the following
hazards.
The repair must not be attempted if the technician is unable to satisfy both himself and relevant site
authorities that the work can be undertaken in a safe manner.
Site-specific safety instructions may cover some test and repair activities and must be observed as
applicable.
The diagnosis and repair of the Laser Jailer system will very likely require access to the inside of the
Interlock Controller in which the Monitor and Detection circuit board is fitted.
The Interlock Controller has mains voltages inside. Whilst these are generally
touchproof to IP2X the technician must be aware that hazardous voltages are
present and take appropriate precautions. This will include personal and site
safety requirements. In some cases, this may require a cordon or other
warning to others that exposed hazardous voltages may be present.
The Laser Jailer system operates on an earthed 24VDC supply produced by a power supply within the
interlock controller. Technicians should be aware that the Monitor and Detection board generates
up to 36V with respect to earth which may be felt on contact.
The technician must ensure that any laser that may be connected to the interlock system is disabled
so that it cannot be operated despite the interlock controller being armed. Preferably this means
isolating it from its power supply and ensuring that no one will reconnect it for the duration of work
on the interlock controller. The work in this manual does not require the laser to be operated.
Approved means of access may be required for tiles that are out of reach from floor level. Site
restrictions regarding working at height may be applicable. Personal protective equipment may be
required for some activities.
This device is intended to be used as part of a safety system which may be used to protect personnel
and equipment from possible injury, damage, or loss.
As such it must be installed and wired according to these instructions and tested by suitably qualified
persons. No attempt may be made to tamper with the parts, open them, or use them outside of the
parameters contained herein.
The units are only designed to be fixed to surfaces using their inbuilt fixing holes. They must not
come into contact with each other or any other moving part when in use. The parts should never be
subject to impact or mechanical strain.
