The Ultra Detection heat sensor provides excellent performance and high reliability in an attractive low-profile body.
It uses a thermistor (thermally sensitive resistor) to sense the rapid change in air temperature that can only be the result of a fire. It provides both fixed temperature and rate-of-rise detection and is suitable for use in homes, hotels, offices and insulated storage facilities.
It is not triggered by dust or other fine particles in the air and is therefore suitable for harsh environments like warehouses and kitchens. It offers excellent resistance to electromagnetic interference to help reduce false alarms.
Features:
- Thermal Rate-of-Rise detection.
- 57°C fixed.
- Bi-colour LED indication ring.
- N/O and N/C contacts.
- 10-32V DC operation.
