This is a particular electronic key usually used in those systems where operate only electronic keys.
MAIN FUNCTIONS:
1) To erase lost or undesired keys from the memory of the controller: how it works:
Control-box KV206 - Select on the numerical commutators of the KEY KILLER the number of the
location in memory of the key you want to erase. Send the controller in the erasing mode by the pushbutton
P2 or, from the reader, via Master key (see instructions of KV 206). Touch the KEY KILLER
against the reader for 1 sec. (red LED on KEY KILLER flashes): now the lost or undesired key has
been erased.
Control-boxes KB 324 MT and KB 304 MT - Select on the numerical commutators of the KEY
KILLER the number of the location in memory of the key you want to erase. Send the controller into
programme mode by the push-button P1 or, from the reader, via Master key (see instructions of the
controllers). Touch the KEY KILLER against the reader for 1 sec. (red LED on KEY KILLER flashes):
now the lost or undesired key has been erased.
| Examples: |
to erase the key n°3 in the memory: select on the KEY KILLER: 003 |
| |
to erase the key n°25 in the memory: select on the KEY KILLER: 025 |
| |
to erase the Master Key, select on the KEY KILLER: 001 |
2) To know how many locations are still available in the memory of the controller; this function is
possible only for the control-boxes KB 324 MT and KB 304 MT connected via interface PF 202 to any
desk printer (IBM compatible). Select on the numerical commutators of the KEY KILLER the number
799. Send the controller into programme mode by the push-button P1 or, from the reader, via Master
key (see instructions of the controllers). Touch the KEY KILLER against the reader for 1 sec. (red LED
on KEY KILLER flashes). The following message will be printed:
... FIRST COD. FREE # ...
... COD. FREE # ...
| Example: |
2 FIRST COD. FREE # 5 |
| |
507 COD. FREE # 5 |
| That means: |
The n°2 is the first location free in the memory of the controller n°5
There are 507 locations free in the memory of the controller n° 5 |
3) To change the identification number of the controller (#) – this function is possible only for the
control-boxes KB 324 MT and KB 304 MT connected via interface PF 202 to any desk printer.
In fact, it is possible that in one system exist several controllers (up to 8) dedicated to control a door, to
control a gate, and so on (for example in a hospital, in a factory, in a car-parking).
In such a situation it is possible to know from which controller the data come, by simply connecting in
parallel the serial outputs of the controllers, and identifying each unit with a different number to print
all the events on just one printer.
Select the number 79 on the KEY KILLER followed by the desired number, from 1 to 8. Send the
controller into programme mode by the push-button P1 or, from the reader, via Master key (see
instructions of the controllers). Touch the KEY KILLER against the reader for 1 sec. (red LED on KEY
KILLER flashes).
| Example: |
794 to identify the unit as n°4 |
| |
797 to identify the unit as n° 7 |
By this operation it will be possible to know every time from which controller come the data.
The number 790 on the KEY KILLER erases the identification number. |
