SPD-3.5-N
Product description 
The SPD-3.5-N detector is designed to detect fires inside buildings and structures, accompanied by the appearance of smoke and an increase in temperature, as well as to transmit a “FIRE ALARM” signal to the control panel.
- Features
- the detector is used in a two-wire loop, the output signal is formed in a contactless manner;
- has a self-diagnostic function with appropriate indication;
- sensitive to a wide range of smoke types, which is necessary for general use in fire alarm systems for buildings (in accordance with the requirements of DSTU EN54-29);
- performs the function of sensitivity drift compensation with the corresponding indication after reaching the compensation limit level (meets the additional requirements of DSTU EN54-29):
- provides indication of operating modes using built-in optical indicators (duty, fire, exceeding the compensation limit level, malfunction);
