SG-A92G-ExExplosion-proof Fire Audible and Visual Alarm / Fire CCCF Certification / IP66 / Energy Storage Battery Cabin Explosion-proof Audible and Visual Alarm

I. Product Overview:

1.1 The SG-A92G-Ex Fire Audible and Visual Alarm (hereinafter referred to as the alarm, defaulted to the intelligent type unless otherwise specified, and can also be set as a general non-coded type) is a product designed to be used in conjunction with our company's bus-type fire alarm controllers. The alarm utilizes microprocessor control, enabling real-time communication with the controller and receiving control commands from it. In the event of an incident, the alarm activates upon receiving the start command from the controller, emitting a dazzling flash signal and a sharp audible alarm signal. Pressing the "Reset" button on the controller returns the alarm to the monitoring state.

1.2 This product complies with relevant standards such as GB/T 3836.1 "Explosive Atmospheres - Part 1: General Requirements for Equipment," GB/T 3836.2 "Explosive Atmospheres - Part 2: Equipment Protected by Flameproof Enclosure 'd'," and GB/T 3836.31-2021 "Explosive Atmospheres - Part 31: Equipment Protected by Enclosure 't' for Dust Ignition Protection." The explosion-proof marking of the alarm is Ex db IIC T6 Gb/Ex tb IIIC T80°C Db, and it is suitable for use in hazardous areas of Zones 1, 2, 21, and 22, where explosive mixtures of Class II A, B, C groups T1 to T6 combustible gases or dusts with air may be present.

II. Product Features:

2.1 Explosion-proof type: flameproof.

2.2 Fully electronic coding with an address range of 1 to 324.

2.3 Polarity-free two-wire bus connection, simple installation and maintenance.

2.4 The alarm mode (audible and visual simultaneously, audible only, or visual only) can be freely set via an encoder to adapt to different working environments.

2.5 The product can also be configured via an encoder as a non-addressable general-type audible and visual alarm.
