AW-CTD322 Two-Wire Conventional Heat Detector

The AW-CTD322 Two-Wire Conventional Heat Detector detects unusual heat changes that may indicate a fire. It responds to heat instead of smoke or flames. Therefore, it suits areas where dust, steam, or fumes may affect smoke detectors.

Reliable Heat Detection

The detector monitors temperature conditions within its coverage area. It sends an alarm signal when it detects a dangerous heat level. As a result, the connected fire alarm system can warn occupants of a possible fire.

Two-Wire Connection

The AW-CTD322 uses a two-wire connection. The same pair of wires supports power and alarm communication with the control panel. Therefore, this configuration reduces wiring requirements and simplifies installation.

Alarm Communication

The detector connects to a compatible conventional fire alarm control panel. When it detects an alarm condition, it sends a signal to the panel. The panel then activates its programmed response. For example, it may operate sounders and other connected warning devices.

Visual Alarm Indicator

A visual indicator helps users check the detector’s status. During an alarm, the indicator provides a clear visual signal. Consequently, technicians and emergency teams can identify the activated detector more quickly.

Installation Areas

Installers can mount the detector on a ceiling or another suitable surface. Common applications include kitchens, boiler rooms, workshops, warehouses, and industrial facilities.

However, installers must select the correct position for reliable heat detection. They should also consider ceiling height, airflow, and nearby heat sources.

Conventional System Compatibility

The AW-CTD322 works within a compatible conventional fire alarm system. Such systems may also include smoke detectors, manual call points, alarm sounders, and control panels.

Before installation, confirm compatibility with the chosen fire alarm panel. This step helps prevent connection and performance problems.

Key Features

• Detects abnormal heat conditions
• Uses a simple two-wire connection
• Connects to a compatible conventional alarm panel
• Sends an alarm signal after detecting dangerous heat
• Provides a visual status indication
• Supports ceiling or surface mounting
• Suits areas where smoke detectors may cause false alarms
• Reduces wiring complexity during installation

Suitable Applications

The AW-CTD322 suits locations with dust, steam, fumes, or rapid air movement. These conditions may reduce the reliability of standard smoke detectors. Therefore, a heat detector can provide a practical alternative in selected areas.

A qualified fire alarm technician should install and test the detector. In addition, regular inspections help maintain dependable operation. Always follow the manufacturer’s instructions and local fire safety requirements.
