Health and Safety
IMPORTANT
When installing the hardware the following should be noted. Please read all these instructions and
save them for later use.
The installation of this system must meet the requirements of the country of installation’s National
Wiring Regulations (BS7671, IET National Wiring Regulations in the UK) and EN60950-1. It must
only be carried out by suitably competent, qualified and experienced personnel.
Failure to do so can result in injury or death by electric shock.
Installation must also comply with any local Fire, Health and Safety regulations. A secured door that
may be part of an escape route must always be fitted with the following.
lA fail-safe lock so that the door will be released if the power fails. Ideally a magnetic lock
should be used as these are less likely to jam or seize.
lA normally-closed break-glass or manual pull in the lock supply wiring so that in an emergency
the fail-safe lock can be immediately de-energised.
Failure to do so may lead to injury or death in the event of a fire.
The controller must be earthed. Isolate the controller power supply before working on the controller.
Failure to do so may damage the unit.
Cabling
The cabling used in the control systems should be routed in a manner to avoid running alongside any
heavy load switching cables.
If this is unavoidable, cross the cable at right angles every 3.3–6.6ft / 1–2m to reduce the
interference.
ESD Precautions
The product contains static-sensitive devices and an earth grounding strap must be worn when
handling the hardware.
RFID Devices
RFID technology is now widely used in a number of industries, it is possible that interaction between
your credential and other devices in the vicinity may cause incorrect operation or recognition. Should
you suspect that you have experienced such a problem, ensure the interfering device is out of range.
This only applies if any RFID devices have been fitted.
WEEE Directive and Product Disposal
At the end of its serviceable life this product should not be treated as household or general waste. It
should be handed over to the applicable collection point for the recycling of electrical and electronic
equipment or returned to the supplier for disposal.
