CODED KEYBOARD MODULE

Technical features:

Supply voltage: ....................................................................................12Vdc or 12Vac 250mA

Acoustic indication: .............................................. confirms the pressed button has been entered

Luminous indications - Green led :

- in stand-by indicates power is on

- switches off to confirm the button has been pressed

- supplies useful information during codes programming

- Red led:

- indicates RL2 relay status

- supplies useful information during programming

Timing: .................................................................................. adjustable from ca. 2s to ca. 30s

Storable codes: .......................... 29 different codes (made of a min of 1 to a max of 7 digits) stored

even during mains failure. Each code can be allotted to either RL1 or RL2 relay during programming.

1 secret code to run programming.

Operation

The MCC 70 digital coded keyboard module energizes two different relays through the 29 codes to be

stored in its EEPROM. During programming it will be decided, code by code, if RL1 or RL2 (fig. 2) relay

shall be energized. If the code digited by the user has been allotted to RL1 relay, when the user digits it

and presses button

to confirm, RL1 relay will be energized for a time that can vary from 2 to 30

sec. according to what was set by means of trimmer TIMER. If the digited code had been allotted to RL2

relay, when the user digits it and presses button

Operation of RL2 relay depends on the position of J2 bridge. If J2 is NO, RL2 relay will operate in mono-

stable way ( like RL1 relay ); if, on the contrary, J2 is YES (bi-stable), RL2 relay will change status every

time a valid code allotted to RL2 relay itself is digited.

Programming with J1 bridge

In order to set the 29 codes it is sufficient to proceed as follows:

a) place J1 bridge on YES. The green led switches off indicating the device is in "programming".

b) digit the progressive number of the location where the number shall be stored (included between 02

and 30). The green led blinks at 5 Hz to indicate the system is awaiting the code to be stored.

c) digit the code to be stored (min. 1 to max 7 digits).

d) press button

to confirm the code to be stored. The red led will start blinking at 0,5 Hz to invite

the user to allot correspondance of the code to RL1 or RL2.

e) press button 1 if code has to be allotted to RL1 or button 2 if it has to be allotted to relay RL2.

Pressing button 1 the red led will switch off to confirm code has been allotted to RL1; pressing button 2

it will light up.

f) press button

to confirm. The green led will make a series of 2 subsequent blinks to confirm the

code has been stored.

Note 1: if the green led switches off instead of sending the 2 series of blinks, this means the

chosen location was already engaged; therefore it will be necessary to erase it before

inputting new data.

Note 2: if during codes dialling more than 5 sec. elapse between pressure of one button and the

following one, the green led will switch off to indicate the stored data were lost and that it is necessary to

re-start the procedure (from point b).

INSTRUCTION MANUAL

to confirm, RL2 relay will be energized.

Attention: the code stored in location 01 is the secret code to run programming without acting on J1

bridge. No relay shall be allotted to this code.

At the end of programming put J1 jumper back to position NO.

Erasing of one location

a) Place J1 bridge on YES and then select the location to be erased digiting the related code (included

between 01 and 30). The green led will start blinking at 5 Hz frequency.

b) Press

button three times to cancel the selected location. The green led will blink for about 2

sec. at 5 Hz frequency to confirm.

At the end of programming and/or erasing operations it will be sufficient to move J1 bridge back to NO,

in order to resume the standard operation.

The device also has two terminals P and P1 for the connection of a button which allows quick release of

the lock during pre-determined hours; this is possible only if the two terminals T and T1 (foreseen for the

possible contact of an external clock, see fig.1) are short-circuited. Doing that, RL1 relay will be

energized (exactly as if a correct code had been digited) for the time pre-set by the trimmer TIMER.

Programming by secret code

All previously described programming and erasing operations can be made without acting on J1 bridge

(and therefore without opening the MCC 70 module), simply digiting the secret code stored in location

01. In this way the green led will switch off to indicate the device is in the " programming " mode. It will

then be sufficient to proceed as previously described.

If required, it is also possible to cancel and re-write a secret code acting on location 01.

At the end of programming it will be sufficient to press button X. The system will, in this way, end the

"programming" mode to enter the "standard operation" one, thereby switching the green led on.

NOTE: If, during these operations, the secret code (location 01) is cancelled, a new one is

not entered, but the X button is pressed, in order to go back to programming it will be

necessary to act on J1 bridge as described in the appropriate paragraph.

The MCC 70 module is supplied with a clean (empty) memory. In order to enter the "programming"

mode, it will therefore be necessary to use the J1 bridge.

Operation during mains failure

The correct operation of the MCC 70 device, even during mains failure, in ensured by the Bitron power

supply with buffer battery (AK 5079).

ATTENTION - IMPORTANT NOTE !!

Install the supplied VDR in parallel to the electric lock in order to prevent spikes generated by

the coil of the lock itself from cancelling the stored codes.
