FR2681890A1 - Device for making secure a telephone network or premises not having energy available - Google Patents

Abstract

Network: room equipped with a second safety flap mounted on hinges or other system, equipped with telescopic arms which can also be locked with the aid of a mechanical key, magnetic key, magnetic cards, or infrared control. The assembly is driven by a box equipped with a portable battery providing the energy. Premises: identical system, bolt applied to the door of the premises and driven in the same fashion as above.

Description

SECURITY SYSTEMS OF A TELEPHONE NETWORK
OR PREMISES WITHOUT ENERGY
The underground networks where the transmission, telecommunications, energy cables or water pipes run are accessible to anyone who knows their route. Telephone cables are for example connected in pulling rooms, under pavement, or sidewalks, and accessible simply by opening closing slabs
In recent years, network operators have sought to secure their telephone cable network against vandalism, embezzlement, deterioration or acts of terrorism.

The systems existing today are either 1) signaling when opening hatches connected to the central by cable to an alarm. Disadvantage: very expensive, and habit-forming phenomenon due to untimely alarms demobilizing the staff, 2) closing of the doors by mechanical lock which the agent can forget to close and which requires the perforation of the door, 3) The locking system pneumatic (expensive) and requiring complete repair of the chamber frame.

The device according to the invention having several options will allow complete security of the network at a lower cost, with security limiting the fall of the hatches in the room, and with selected control of the participants by key or magnetic card. see representative figures 1,2,3.

The device characterized in that it comprises a second hatch installed under the outer hatch mounted on a hinge or other fixing system (Fig. II / 2) preferably made of pressed sheet metal or other materials, with the standard dimensions of the chamber openings .

This second hatch is equipped with a lock (Fig.II / 4) either mechanical or electric which comes to block the hatch in the closed position on an angle iron fixed to the wall (Fig.II / 3).

The lock being fixed under the hatch, this hatch is provided with telescopic arms (Fig. II / 1) facilitating the opening.

1st option: opening the lock mechanically by magnetized key.

2nd option: opening of the electrically controlled lock by magnetic key (Fig. I / 1). The energy supply being produced by a portable, rechargeable battery located outside the chamber (Fig. I / 2) and connected by 2 wires (Fig. I / 3) to a socket located on the hatch, it - even connected to the lock. A push button will release the energy required to open the lock (Fig. I / 4).

3rd option: electrically open the lock, controlled by a magnetic card (Fig. III / 1) whose reader is located on a box incorporating a battery allowing the lock to operate. The box is connected by 2 energy wires to the hatch and 1 control wire; a microprocessor controls the opening of the lock.

A push button located on the box will release the energy necessary for the operation of the lock after reading the card inserted in the box and controlling the microprocessor.

This device allows, after programming the microprocessor, to select access to the category of personnel authorized to intervene.

This device can be equipped with an infrared control replacing the magnetic card.

This same device can be installed and used on the doors of sub-distributors, boxes or buildings.

A mechanical key (Fig. I / 5) will, in all cases, unlock in the event of a malfunction of the electrical system.
