Commercial Support Areas: Underground parking lots, boiler rooms, electrical rooms with
combustible gas risks
Core Advantages
1. Intrinsically Safe Explosion-Proof Certified
The product has passed strict inspection by the National Center for
Quality Supervision and Testing of Explosion-Proof Electrical
Products (CQST) with Ex ib IIC T6 Gb marking, suitable for
explosive environments containing IIA, IIB, IIC class T1-T6
combustible gases. The intrinsically safe design requires
connection with a safety barrier, ensuring that even in case of
failure in hazardous areas, it will not generate sparks or high
temperatures sufficient to ignite explosive gases, providing
reliable safety assurance for high-risk places like petrochemical
facilities.
2. Microprocessor Control Stable Performance
Built with a high-performance microprocessor and SMT surface mount
technology, the components have good consistency and high
reliability. Intelligent algorithms accurately identify button
activation status, avoiding false alarms. Electronic addressing
allows on-site programming with a dedicated encoder, with an
addressing range of 1-200 points, facilitating engineering
commissioning and later maintenance.
3. Non-Polarized Two-Bus Long-Distance Communication
Adopting non-polarized two-bus technology, the standby current is
≤0.3mA and alarm current ≤1mA, achieving extremely low power
consumption. The communication distance can reach up to 1000
meters, supporting coverage of large industrial areas. The
non-polarized bus design eliminates the need for polarity
distinction during wiring, significantly reducing installation
difficulty and labor costs.
4. Plug-In Structure Easy Maintenance
The button body adopts a plug-in structure design. During
installation, simply insert the encoded body into the base and
secure with self-tapping screws. Disassembly and maintenance are
equally simple and quick. The operation panel must be reset with a
special key after being pressed, preventing unauthorized operation
and ensuring system management security.
5. Clear Indication Easy Status Recognition
The panel features a red fire alarm indicator light that flashes
momentarily in normal monitoring status and becomes steady red when
activated. The status display is clear and intuitive. Even in dimly
lit industrial environments, the working status and alarm status of
the button can be easily identified.
Explosion-Proof Safety Instructions
This product is an intrinsically safe explosion-proof device. The
following requirements must be strictly observed during use:
Must be used with a safety barrier that has obtained an
explosion-proof certificate
The positive and negative terminals of the safety barrier input
must not be reversed
When multiple safety barriers are used in the same circuit, they
must be connected in parallel at the input end; cascade connection
is prohibited
Never wipe the device housing with a dry cloth in explosive
environments
For cleaning, perform in a well-ventilated area without gas
leakage, and wipe with a wrung damp cloth
This product is a single-use device; once damaged, it cannot be
repaired
Technical Specifications
Commercial Application Value
Ensure Safety in High-Risk Places: Intrinsically safe explosion-proof design meets fire protection
requirements for hazardous areas such as petrochemical and gas
facilities, effectively preventing explosion risks.
Reduce False Alarm Losses: Microprocessor intelligent recognition accurately identifies
button activation, reducing production interruptions and
unnecessary evacuations caused by false alarms.
Save Construction Costs: Non-polarized two-bus design simplifies wiring processes, saving
cable and labor costs; long-distance communication capability
reduces the need for relay equipment.
Efficient Management: Special key reset prevents unauthorized operation; plug-in
structure facilitates maintenance; clear indicator light status
reduces operational difficulty.
