Key Features of Four/ Eight Point Flameproof Safe Annunciation System

• This Annunciation system is a combination of intrinsically safe and flameproof technology & it is suitable for Hazardous Area, gas group to IIA, IIB, Zone 1 and 2.
• Fault indication: In big sized windows giving a clear visibility.
• Audio signal: By inbuilt intrinsically safe buzzer or by external warning device
• System type: 1] Test / Accept / Auto Reset
• Fault inputs can be No type or NC type [potential free inputs].
• The whole system runs on intrinsically safe power supply and control units kept in flameproof enclosure.
• Operating voltages: 24 V DC / 24 V AC / 230 V AC.
• Annunciation windows, Test and Accept Push Buttons are intrinsically safe.
• System availability: From 4 point system to 30 point system
• Zero risks and Hazards due to intrinsically safe
• Potential free Inputs can be directly taken from any non flameproof or normal device such as level, temp, pressure, flow or any other type of potential free input.
• By using system, it reduces the total cost of the system to the extent that even the field devices such as level, pressure, temperature switches etc. used for the system can be non flameproof devices.
• System allows to attend, maintain, or to change the legend of the intrinsically safe windows even in live condition. This is not possible in conventional FLP system.
