Intrinsically Safe Telephone

Intrinsically safe telephones are communication devices intended for use in hazardous situations where combustible gases, vapors, or dusts could ignite and cause an explosion. These phones are meticulously engineered to prevent the production of sparks or heat that could ignite the surrounding air, ensuring the safety of personnel and equipment in such high-risk areas.

Main Technical Parameters

1. Working voltage: DC18.0V; Voltage fluctuation range: DC15V~24V; Working current: <250mA;

2. Battery pack parameters: Nickel-metal hydride AA (1.2V × 8 cells in series), 2000mAh; Rated voltage (Ve): 9.6V;

3. Maximum open-circuit voltage of the battery pack: 12V; Working current of the battery pack: ≤1A;

4. CAN transmission parameters:

a) Transmission mode: Master-slave, asynchronous, half-duplex, CAN bus;

b) Number of interfaces: 1 channel;

c) Transmission rate: 10Kbps;

5. Loudspeaker sound intensity ≥95dB.

Features

The device facilitates various operations including communication, dialing, voice alarms, and address coding. It features an emergency stop lockout mechanism that activates either by pressing a lockout button or pulling a cable, triggering an emergency stop along the line. Lifting the button restores the lockout condition.

Advantage

These phones are made of non-sparking materials, so they will not produce enough energy to ignite dangerous materials.

Constructed from sturdy, impact-resistant materials to survive tough industrial settings.

Intrinsically safe cellphones are sealed to keep dust and water out and their safety features intact.

Intrinsically safe phones include large, easy-to-use buttons and a clear display, allowing for intuitive use even in adverse settings.

Add features like a strong ringtone or alert to ensure that the phone can be heard in noisy places.

Supports advanced communication capabilities such as hands-free operation and connection with existing communication systems.

Application

The mining intrinsically safe loudspeaking telephone is suitable for use in underground coal mines and coal preparation plants with the risk of gas and coal dust explosions. It can be used for communication and coordination in underground coal mines; specifically, it is ideal for use in working faces, inclined shafts, belt conveyors, and other areas where dial communication is necessary.
