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.

•  The earth stud connection inside the back box should then be connected in the same way to the building’s earth connection.

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.
