The EVA-PYH is an attractively-styled, low pro le
combined photoelectric smoke and heat detector for use with the re alarm control panel of NFU-7000 series.
This detector is an analog detector that has enabled each detector address to provide exact detector loca- tions. The smoke sensitivity of this detector can be programmed using the control panel software to suit the environment. The detector sensitivity is continu- ally monitored and reported to the panel.
The EVA-PYH has a new sophisticated smoke chamber design and an orange sensor LED which can provide the same sensitive detection regardless of the type of smoke.
This detector has a chemically etched, stainless steel insect screen therefore reducing the ingress of insects and airborne contaminants.
The EVA-PYH initiates an alarm in response to both rapid rate-of-rise conditions and xed heat (57°C). Heat portion incorporates a highly linear thermistor circuit, with the thermistor mounted externally. The specially designed cover protects the thermistor while allowing maximum airflow.
