Description

Models EVA-H2 and EVA-H2-H is an attractively-styled, low pro le heat detector for use with the Fire Alarm Control Panel of NFU-7000 series. These heat detectors are intelligent (addressable) detec- tors that have the ability for each detector address to provide exact detector locations. The detector sensitivity is continually monitored and reported to the panel. The detectors incorporate a highly linear thermistor circuit, with the thermistor mounted ex- ternally. The specially designed cover protects the thermistor while allowing maximum air ow. The thermistor circuit produces a voltage proportional to the temperature which is scaled, and transmitted as a digitally encoded value to the control panel.
The EVA-H2 and EVA-H2-H require compatible ad- dressable communications to the control panel in order to function properly. All detectors have random addresses from the factory before installation. The EVA-AD2 Address Programmer is used for setting the address between 1 and 254 decimal of all devices prior to installation. Once addressed connect these detectors to only UL listed-compatible control panels.
The EVA-H2 is a 8.3°C (15°F) rate-of-rise tempera- ture heat detector with 57°C (134°F) xed tempera- ture alarm.
The EVA-H2-H is a high temperature heat detector with 83°C (181°F) xed temperature alarm.
