Coded Access Locks

A code lock can be used in conjunction with any type of electronic locking, such as an electric strike, mag-lock, motorised lock mechanism. Quite often coded access is combined with a door entry system to allow residents of an apartment or office block a way to unlock the door without having keys or fobs. A code can be given to people such as postal workers or carers to gain access.One problem with coded access can be that the code is found out by too many people, which reduces  the security to a point where it is no longer effective, however most systems allow an authorised person, with the correct master code to be able to easily change the user code. All coded access systems fitted by ADI can have the user codes changed by the end user without the need for a visit by an engineer. We can of course do this for you if you prefer or have lost the master code.

  • Backlit keypad - this illuminates the numbers to make it easier to see at night

  • IP Rated for outdoor use in extreme weather conditions

  • Supply voltage 12v /24v AC/DC

  • Audible tones to indicate lock state

  • Visual indication to indicate lock state (usually green and red LED's)

  • Surface / recessed mounted on the wall

  • Multiple codes (some can hold 1000 different codes)

  • Single or multiple relays (can control 2 doors or 1 door with a lockout code to prevent it working when entered)

  • Relay contacts inside the unit (less secure)

  • Relay contacts inside the building (more secure)

  • Anti-vandal

A code lock can be used added to most existing door entry systems to give an alternative way to unlock the door.

It can be combined with a time clock to control when the codes can be used. Making it ideal for offices or factories to restrict access to employees outside of working hours.

With a 2 relay system, a second code can be used as a 24 hour or managers code which works all the time, even when the 1st code is inactive.
