Detnov DTD-215A

The Detnov DTD-215A operates as a combined heat detector. This means it can detect both when a fixed temperature threshold is exceeded and when the temperature rises at a specific rate. The thermal sensors inside the detector continuously measure changes in ambient temperature. These measurements are compared with predefined thresholds. The detector raises an alarm if either threshold is exceeded.

• Fixed Temperature Threshold: The detector raises an alarm when a specific temperature is reached. This is more suitable for slow-developing fires.
• Rate of Temperature Rise: The detector raises an alarm when it detects a temperature increase at a specific rate. This is more effective for rapidly spreading fires.

Advantages

• High Sensitivity: Its combined design provides more sensitive detection across different fire scenarios.
• Addressability: Identifying exactly which detector has raised the alarm speeds up the response.
• EN54-5 Certification: Compliance with the European standard guarantees the product’s reliability and quality.
• Cad-150 Compatibility: It can be easily integrated with other Detnov products.
• Long Service Life: Manufactured using quality materials for a long service life.
• Low Maintenance Costs: It does not require regular maintenance.

Disadvantages

• Potential for False Alarms: The risk of false alarms may be higher, particularly in industrial environments or locations subject to frequent temperature fluctuations.
• Installation Location: Correct positioning of the detector is critical to its detection performance. Incorrect positioning may cause false alarms or delayed detection.
