It
is destined to be used at all types of offices (in
banks, mainly), where the clerk and the public find
it hard to communicate due to the way the office
counter was built.
The two communication lines are blocked in the stand-by mode. When a certain power sound signal appears at one of the microphones, that line is activated (the power limits for activating the lines are adjustable).
In case there are sound signals at both microphones, the more powerful signal activates the line. In case both lines have the sound signal of equal power, the "operational microphone - outside speaker" is activated.
The sound signal has a constant value in the speakerphones thanks to an automated control system, and does not depend upon the microphone sound which may vary within rather large limits.
The equipment is delivered with high quality finishing, the metal parts are electro statically painted, thus having a high mechanical protection.
The component parts of this equipment are of highest quality. This equipment has been patented by the TRADE AND PATENTS STATE OFFICE IN ROMANIA in 1999. |

S.C.DOUBLEJOHN Prodservice S.R.L., produced an "Equipment used to rescue people confined in narrow spaces, model JJ-15".
The equipment was designed and manufactured in order to rescue people
confined in narrow spaces such as wells, fountains, caves, water ducts etc.
The electronic part can also be used to investigate buildings destroyed by natural
disasters and where survivors may still exist. The investigation probe having
small dimensions can be introduced between the ruins in order to investigate,
assess and analyse the existing situations, in order to prevent undesirable events
which might appear in the course of rescue operations.
The electronic equipment can also be used to inspect technological ducts. Being
equipped with the investigation probe, the inspector can communicate with the other
members of the team, exchanging technical information and broadcasting images
from the inspection place.
This equipment consists of two parts: the electronic equipment and the
mechanical equipment.
The electronic equipment is made of the "Investigation Probe" (I.P.) wire
connected, up to 100 m long, to the "Central Unit" (C.U.).
C.U. has the role to monitor and control the rescue activities, through video and
audio system, a 7 inch-LCD video monitor, a microphone and a loud speaker,
connected to a controller module; the microphone and the loud speaker of the I.P.
are as well connected to this controller module. Due to this controller module, the
audio connexion is extremely sensitive, permitting the weakest vital signs to be
sensed, such as heavy breathing with moaning, when I.P. is close to the confined
person.
I.P. wire connected to the C.U. disposes of a video camera, a LED diode mini
projector of high light intensity and power saving, a microphone and loud
speaker. Due to the audio/video communication system, communication
connexions may be established with persons being in extreme situations in
order to assess their physical and psychological estate. The fact that there is
a communication channel increases the person's hope to be rescued.
I.P. can be introduced in numerous narrow spaces, difficult to access, through a
bar made of duct segments of aluminium alloy, which can interconnect easily,
rapidly and safely. Being light, it can be easily manipulated by the investigator
without any particular physical effort.
Another probe can be connected to the C.U., which it consists of a mini
projector and a video camera which is protected in order to be used in aquatic
environments, having enough transparency degree to ensure usability of the
images broadcasted by the camera and rendered on the monitor.
The equipment can be charged by the electric network 230V/50 Hz c.a. or by its own accumulator which ensures an energetic independence of almost 6h at its total
capacity. For emergency situations, it can be connected for charging to an exterior
accumulator.
In case of natural disaster, the fact that the equipment is charged from a source
independent from the electric network makes it to be highly used; used as well in
places where there is no other power source.<>
The mechanical equipment consists of square section tubes of aluminium alloy. The
particular composition of the tubes ensures a high mechanical endurance. The 2 metre
tubes are easily, rapidly and safely interconnected until they reach the wanted length.
The first segment has a particular construction permitting it to become "L-shaped" and
thus becoming kind of a "chair".
Due to the existence of the investigation probe I.P., the rescue operation is
permanently monitored by the recue team which is able to change the rescue type
when unforeseen situations appear. The mechanical equipment is completed by a
subassembly for position stabilisation which is jointly connected to the first tube
segment.
This subassembly stabilises the position of the confined person, during the
extraction operation, through another system of circular section tubes of aluminum
alloy. |

This equipment is designed and manufactured to be used mainly for increasing security of rooms with special doors (bank safe deposits, strong boxes, etc.) Access is blocked by means of a mechanical shutter that is operated by hand following the cipher combination and time delay. The device is located on the outside of the door (safe deposit room, cash box) so that there is no need to interfere with the inside mechanism of the door which can work without any obstacle from the lock unit. It has the advantage, besides keeping out the unauthorized persons, that it can be installed on the equipment already there, without any changes of the locking systems.
The access code can be mechanic or electronic, the advantage stays with latter , which can be programmed, thus having a larger number of combinations and a much easier operation.
This equipment has been installed at the Romanian Bank branches offices

The electronic code for access control is meant for access doors of dwellings, institutions, storage rooms or other spaces for special purposes.
It can also be used to activate or deactivate the danger alarm and monitoring systems.
The equipment includes:
- keyboard, including 16 keys distributed on four rows and four columns, installed outside, in access area;
- electronic unit;
- supply source, that can be: charger connected to the 220 V single phase electric network; 50 Hz battery, or accumulator.
The last two equipment components are set inside.
The equipment can be used as follows:
==> version 1: impulse for short command of access;
==> version 2:various commands for activation, and deactivation;
==> version 3: unique command for activation, and deactivation.
Mention should be made that unlike the first version, when a short time access impulse is ordered (2 - 3 seconds), during the last two versions, the last order is held until a new order is given.
The producer company sets the version to be used at the client's request.
The whole manufacture and finishing of the equipment are of highest quality, and highly mechanic protected keyboards can be delivered upon request.
