The Buttons wireless transmitters are powered by batteries easily available on the market; mobile receivers (pagers, disks, watches) are powered by rechargeable lithium batteries of our production. These mobile receivers are recharged with supplied chargers.
The other products that have a fixed positioning (keyboard transmitters, signal repeaters, fixed digital displays) are powered by 12V with a 220-230V AC current transformer supplied.
They are small mobile receivers to keep in your pocket, wrist, belt or neck. They are used in many areas to quickly alert a person to go to a place in the room.
For example :
– in the factory a maintenance technician can see on the display of his wrist watch from which workstation he was called;
– in a logistics center the truck driver will have a disk that vibrates and sounds when his turn arrives to load or unload the goods;
– in a restaurant the customer will have a disk that vibrates when he has to go to the counter to pick up his plate;
– in a nursing home the nurse will see the call of assistance on the display of her wrist or belt watch from which room or bed.
Wireless (literally, without any wires) paging systems are devices that use radio waves to transmit signals to send messages.
The wide range of wireless pagers and buttons constitute a system of devices to resolve any need requiring a RAPID CALLING system without having to shout: Management of queues, Call Employees, Call foreman, Call Driver, Call Waiter, Call Nurse, Call Forklift Driver.
No, all Linkman equipment has a low radio emission and comply with the European standard EN 300 220-3 on electromagnetic compatibility.
The field of application is very wide: wherever there is need to call the service or assistance in a local area (to call the foreman at the factory, to call the storekeeper from the desk, to call the nurse in nursing home or in hospital, to call the sales clerk in a store, to call the waiter from the restaurant / bar / pizzeria table). The installation of the Linkman wireless transmitters is very simple and economical as it does not require any wiring.
The frequency is 433.92MHz assigned for equipment with limited range (SRD: short range device).
With the law that we apply, the transmission power of 10mW allows a range of about 100m. The flow can be influenced by architectural structures (reinforced concrete, iron). If this range of action is not sufficient, it is very important to know that with the signal repeaters it is possible to extend this range even hundreds of meters up to cover the affected area.
The wireless transmitter buttons can be mounted onto tables, walls or other fixed surfaces. In the cases where tables are covered in tablecloth, the wireless buttons can be mounted in Plexiglas (ST-01 or ST-02) and customized such that the larger volume makes theft more difficult and the customization reduces its resale value.
The keypad transmitters such as the PT-T100 are powered at DC 12V via AC220-230V transmitters.
The power is 10mW as established by the European Commission regulations 2000/299 / EC class1 / subclass20 (Non specific short range devices).
The LM-T802 displays are powered at DC 12V via AC 220-230V transformers.
The LM-T800, LM-T910, LM-T9000 are powered with a A23 12V battery that can be replaced by opening the cover at their base.
Depends on the frequency of use of the buttons, on average every one to two years (A23 12v battery).
At least 8 hours of continuous usage. It typically takes 4 hours to recharge fully.
One year by the manufacturer
