JTY-GD-A30E Point-type Photoelectric Smoke Detector

Product catalog summary
Product Overview
The JTY-GD-A30E is a point-type photoelectric smoke detector designed for environments with significant smoke during fires but minimal smoke otherwise. It features a built-in microprocessor, supports electrical coding, and connects to a fire alarm control system via a two-wire bus.

Product Features
- Electronic coding and address rewriting capability.
- Real-time data processing with storage for 144 historical data points.
- Temperature, humidity, and dust compensation, along with sensor fault detection.
- Non-polarity, two-bus connection for easy installation and maintenance.

Technical Parameters
- Complies with GB 4715-2005 standard.
- Non-polarity two-bus wiring system.
- Working current: <300uA (inspection), <1.5mA (alarm).
- Dimensions: 105mm diameter, 43mm height.
- Installation height: ≤12m.
- Operating temperature: -10℃ to +55℃, RH ≤95%.
- Address codes: 1 to 324.
- Protection area: about 60m².

Installation and Debugging
- Follow national standards GB 50116-2013 and GB 50166-2019 for installation.
- Use RVS twisted pairs for signal buses L1 and L2.
- Ensure proper coding and connection to the fire alarm control panel.
- Conduct an alarm test post-installation.

Precautions
- Avoid address conflicts on a single bus circuit.
- Keep the protective cover on until installation.
- Comply with national standards for detector placement and quantity.

Maintenance and Upkeep
- Notify management before maintenance.
- Check fire function annually.
- Shorten maintenance periods in dusty or high wind areas.
- Free repair or replacement for defects within one year, excluding misuse.

Failure Analysis and Elimination
- Common issues include coding failures, login issues, and false alarms.

JTY-GD-A30E Point-type Photoelectric Smoke Detector-1

Product Manual Version: V1.0 Please read this Manual carefully before installing and using the product 1.1 JTY-GD-A30E point-type photoelectric smoke detector (after this referred to as detector) is a photoelectric smoke detector. The detector has a built-in microprocessor, supports electrical coding, and accesses the compatible fire alarm control system through the two-wire bus. The detector can collect the smoke concentration data in real-time, and transmit the data to the fire alarm control system, and receive and execute the control command given by the fire alarm control system. 1.2 The detector is suitable for a significant quantity of smoke when a fire occurs and no smoke under normal circumstances.Such as restaurants, hotels, teaching buildings, office buildings, computer rooms, communication computer rooms, libraries, archives and other industrial and civil facilities. However, it is not suitable for places with a lot of dust and water mist retention, where the places may produce steam and oil mist and retain smoke under normal circumstances. 2.1 It can realize electronic coding and rewrite the address via coder in situ. 2.2 Within a single-chip microcomputer, it can process the sampling data in real-time, save the latest 144 historical data and realize a curve tracing for the field situation. 2.3 It has a temperature, humidity and dust accumulation drift compensation function and a sensor fault detection function (fault reporting to fire alarm control panel). 2.4 Non-polarity, two-bus connection that ensures convenient installation and maintenance. 2.5 Designed with an upper cover and a lower cover and installed on an independent base, it can be installed, debugged and maintained conveniently. www.saniiang-security.com Page 1 of 5 Template (Version):T-006(V01.05)
