DMP 1183 Series Wireless Heat Detector
Digital Monitoring Products (DMP) of Springfield, Mo., unveils the 1183 Series wireless heat detector. The ceiling-mount detector is available in two versions, one for fixed temperature and another for combination rate-of-rise and fixed temperature.
The 1183-135F is a fixed temperature detector that sends an alarm to the panel if the temperature exceeds 135° F. Additionally, the 1183-135R is a combination fixed temperature and rate-of-rise detector that sends an alarm if the temperature reaches 135° F or if the temperature increases by 15° F or more per minute.
The detector is compatible with all DMP panels that are equipped with wireless capability. It includes DMP wireless features that speed and simplify setup, including the Survey LED that provides visual confirmation of communication with the panel. DMP Two-Way technology allows the product to send a signal to the panel and receive an acknowledgement, avoiding repetitive signaling and extending battery life to more than four years, according to the company.
