Using the controller software, a database of visitors is created, each visitor is assigned an electronic pass with a unique electronic code (card, bracelet, key fob), with which the system will identify the visitor as a user.

At each control point are installed RFID–entry/exit readers that will identify the electronic pass. Kcontroller always checkthere are can this visitor in a given moment, pass through a given point in any of the directions and solvethere are allow or deny passage.

Features of the device:

– there is no subscription fee

– data transfer via GPRS

– organization of additional signaling

– the built-in battery allows you to maintain communication during the disappearance of external power

– Built-in temperature sensor

The device is intended for pricing the use of the elevator.

Information exchange with the server and dispatcher is carried out with the help of GPRS. It is possible to configure information exchange over the GSM network: calls, SMS.
The connection to the GPRS server is permanent, in the event of a disconnection attempt is made every second.

To the warehouse systems include:

1) a control device consisting of a processor, a GSM modem with a remote antenna,

external control and control channels – located outside the elevator cabin;

2) an RFID device that reads access codes is located in the elevator cabin and on the first floor;

Device functions:

Performs ACS functions (RFID card readers, internal database of up to 1000 cards and controls power channels of the “dry contact” type of permission to call the elevator to the 1st floor and permission to send the elevator;

Optionally captures readings of universal security external sensors (monitors the state of the end room security sensor, light sensor, temperature and humidity sensor and transmits data via GPRS to the server indicating the time of the event from the internal non-volatile clock.

The device is powered by an on-board DC or AC network with a voltage of 90 to 240 volts. There is a built-in 4V battery that allows you to work in autonomous mode for up to 6-8 hours.

The battery is recharged automatically from the on-board network. There is a sensor that measures the battery voltage.

When switching from external power to backup and back (disappearance and appearance of the voltage of the on-board network), a change in the state of the alarm inputs is notified via GPRS or a pre-set number using SMS or Telegram.

User Interaction

In the initial state, the elevator buttons are locked. The passenger, approaching the elevator, holds up his card to the card acceptor. If his card is active, that is, it is included in the list of those allowed to access, the blocking is removed, which the passenger knows about by a light and sound signal. When the elevator arrives at the floor, it will be necessary to re-apply the card to the reader in the elevator cabin. The lock from the buttons of the elevator cabin is removed, pressing the desired button will lead to the normal operation of the control station and delivery of the passenger to the desired floor. If the card is not active, the passenger will not be able to use the elevator.

The unique number of the passenger card is the access key (hereinafter referred to as ID). The list of active IDs is stored in the device memory. The list can be edited remotely, without maintenance personnel going to the facility and without residents visiting the relevant institutions.

To update the ID list, a computer or smartphone with Internet access and a reader that can be used to enter new cards is enough.

The software creates a database of resident IDs based on apartments. Thus, it is possible to quickly forbid or allow the use of elevators to residents of certain apartments as many times as needed, which makes access management simple and clear.

The elevator access control system prevents unauthorized persons from entering the elevator cabin. Due to this, the number of trips of the elevator is significantly reduced, therefore the wear and tear of its mechanical parts. Electricity consumption is also reduced. It is important to note that the possibility of intentional and accidental damage to the interior is reduced.

The control channel is capable of operating with a current of up to 15A for capacitive loads, which corresponds to 3.3 kW at 220V. For inductive loads, the current should not exceed 7A.

Memory 

The device has a memory that is designed to store phone numbers that are followed by a notification (SMS, call) in the event of an alarm. In total, the device is able to remember up to 6 numbers for notifications. Numbers are stored in EEPROM, they will not disappear from memory when the device is turned off.

The first three numbers are required for SMS accident notification. And if there is a fire or other emergency, the device will try to call numbers from the list 4-6. You can write the same number in both lists. The device can be controlled from any phone number, there is password protection.

Built-in clock

The alarm system includes a real-time clock, which is required for the automatic operation of the device. So, for example, you can use the Timer function to set the boiler or lighting to turn on and off automatically at a given time. For example, if you need to turn on the lighting in the aquarium only at night, the device will easily cope with this task. He will do this daily, weeks, days, months and years.

Temperature sensors

The device supports up to 10 temperature sensors. If the temperature exceeds the set limits, the device will send an alarm SMS or try to call. If the temperature has returned to normal, you will also know about it.

It is possible to control the power channel and monitor the state of the temperature sensors through our server (access is through the site from any smartphone or computer). To do this, it is necessary to specify in the order that the GPRS version of the device is required (the service is included in the price of the device).

Accelerometer

The device has a three-axis shock sensor that can be adjusted to a sensitivity of 0.1 to 10G (free fall acceleration). This sensor is needed in case the protected object is stolen along with the device. It can be a safe, a switch, and so on. The device will read the position of the sensor every 5 minutes and thereby determine the location of the device. Data will be sent via SMS with a link to Google maps.

Built-in battery

If the power suddenly goes out, which happens in the event of an accident or robbery, the device will not get lost and will not stop working thanks to the built-in battery. It will send an alarm SMS that the power has been cut. In autonomous mode, the device can work up to 6-8 hours.
