ELECTRIC LOCK AND VOLT FREE CONNECTIONS
An electric lock (fail safe or fail secure) cannot be connected directly to the
KR-AV
unit. The “
REL
” output can be connected to a
remote relay (
Art.506N
) which can then be connected directly to the lock. An additional 12Vac or dc power supply (depending on
the type of lock fitted) may also be required. Follow
Fig.4
for fail secure lock release wiring and
Fig.5
for fail safe lock release wiring.
If volt free wiring is required,
e.g.
volt free connections to a set of gate or barrier controls, then simply follow
Fig.4
but omit the lock
wiring and instead connect the
CO
/
NO
relay terminals directly into the appropriate trigger input on the gate or barrier controls.

PANEL CARE AND MAINTENANCE
As the panel is manufactured from 12 gauge brushed stainless steel it is important that the VR plate is cleaned on a regular basis
to prevent dirt build up and tarnishing. A clean and soft cloth can be used with moderate warm water or non-aggressive cleansers.
Additional care should be taken to follow the grain of the metal when polishing and always only polish in one direction to avoid
light scratching of the plate. Also try to avoid any polish build up around the panel’s button which may prevent the button from
operating correctly.
DO NOT USE ANY OF THE FOLLOWING:
• Abrasive liquids;
• Chlorine-based liquids;
• Metal cleaning products (including Sidol stainless steel cleaner as this can affect the engraving);
• Hydrochloride bleaches.
