Night depository ASK 50

Night depository ASK 50

The need for maximum security, simplicity and rapidity of use, the certainty of a cross-check between bank and customer of a successful deposit and memorization of transactions have led to the construction of this modern night depository.
The salient points of the ASK-50 model night depository are:

  • maximum opening and depositing simplicity
  • the certainty of a successful deposit, a record of who has made a deposit
  • selective cancellation of customer’s key in the event of loss
  • the solidity of the hopper which makes it impossible to wrench out or smash in, and above all is proof against “fishing”.

As well as the above functions, the depository is equipped with the most modern locking systems such as electronic keys for deposits, interchangeable digital combination keys for opening the safe with all features for anti-theft and anti-robbery and handling of withdrawal by valuables transporters.
If the safe door is external for valuables transport, an anti-vandalism door covers the open/close device (only ASK-50 with sack). A motorized hopper with special sensors to record the positive movement of the deposit into the receiving safe is situated on the outside.

The night depository has been certified to European standard EN 1143-2:2001, N-III rating. As well as strength of the safe, these standards provide for all security tests on the hopper.


The container sack is solidly anchored to the safe. A special shutter has to close to allow the sack to be extracted from the safe. If the shutter is not closed, the sack is mechanically blocked and cannot slide out on its runners.
In addition, an electrically controlled catch prevents extraction when there is a container in the hopper above the sack.
A double bitted key is required to open the shutter which closes the sack. The shutter is held by a special catch which is unlocked with a push button. The push button itself is protected to prevent accidental closure of the shutter during transport.
A special anti-blinding electronic sensor verifies that the sack is actually present, so preventing the hopper being opened if the sack is not inserted or if the safe is not closed.
The sack is made of tear-proof, waterproof fabric fixed to the frame with screws that can be loosened only when the sack is open. Seams are protected with additional straps to ensure against any fraudulent opening of the sack without the correct keys. br> The sack can hold 40 containers, even if the control electronics will prevent the deposit of more than 38 pieces per sack. If self-sealing envelopes are used, the capacity of the sack is around 250 deposits.

Deposits can be made with either rigid containers or suitably-sized envelopes.

The system is based on the principle of providing the customer with an electronic smart key (controlled access) to allow identification and recording of each deposit. The system includes a reader, a transactions recording system and an alphanumeric keypad.
Two essential factors have been taken into consideration in the design of this night depository: SECURITY and PRATICALITY.


  • Due to its high mechanical solidity, the loading hopper is absolutely immune to tampering and either wrenching out or smashing in.
  • In the event of a mechanical attack, a special irreversible diaphragm automatically slides into place between the outside and the inside of the receiving safe.
  • A further effective defence is provided by the configuration of the hopper drum in acetylene torch-proof steel filled with a corundum conglomerate.
  • It is equipped with two photocells (ANTI-BLINDING), one which controls the inside of the loading hopper and one in the chute to the safe below, so allowing control of all the stages of the deposit to ensure it falls correctly into the receiving safe and identify any attempt at tampering.
  • Each electronic key supplied to the customer is unique in the world (the code is on 48 bits which corresponds to around 280,000 million combinations).
  • Each night depository recognizes ONLY enabled keys and makes identification ONLY of these.
  • Each key is ILLEGGIBLE and UNCOPYABLE;
  • The key provided to the customer is in stainless steel and practically indestructible. The key is contained in a convenient keyholder.
  • The “keyhole” is a stainless steel disc WITHOUT holes or slots, and is therefore completely protected from acts of vandalism.
  • The access code is required to enable/disenable a key.


  • Use of the key is identical to using a mechanical key: it is enough to bring the key close to the receptor and the validation and recognition procedure is automatic. In addition, the motorized opening system makes the operation simple and quick.
  • The key is not cumbersome.
  • In the event of loss, cancellation of the lost key and provision of a new one is extremely simple, so that in the case of the loss of a key IT IS NOT necessary to change the lock or take any steps with regard to other customers’ keys.
  • A non-volatile memory records the last 6,000 transactions (deposits), memorizing the date/time of the transactions and the customer’s identification code. The transactions can be visualized on an alphanumeric display, printed from a local printer or transmitted on a serial line to a central computer.
  • The same key can be enabled to access more than one night depository, allowing customers enabled to deposit in more than one night depository to have a single key.
  • The display always shows the total number of bags deposited (resettable manually after emptying the safe) and the historic total (non-resettable, used for statistical purposes to assess the rate of use).
  • The clock/calendar continues to keep time also when there is a power shortage.


  • A warning light advises the customer whether the night depository is in service or not.
  • An auxiliary entrance allows the night depository to be locked (for maintenance work or alarm situations). Locking/unlocking can be also controlled by serial line.


  1. Ensure that the light next to the “keyhole” is off.
  2. Bring key or badge up to the lock. If it is recognized, the hopper automatically opens.
  3. When the bag is introduced, the hopper automatically deposits the bag in the safe, recording completion of the transaction and the customer’s identity code. The LED also flashes briefly to indicate passage of the deposit to the safe.
  4. “Deposits can be made either in standard 25 or 50mm high rigid containers or in self-sealing plastic or paper envelopes of suitable dimensions.
