Nittan Smoke Detectors

A Nittan smoke detector is a Nittan Evolution addressable detector for fire alarm systems; the EV-P, for example, is a photoelectric smoke detector for use with Nittan FSK protocol control panels. Decide whether the point needs smoke detection alone, smoke with a sounder, or combined smoke and heat sensing, then confirm the panel uses the Nittan Evolution FSK protocol.

Optical smoke detection

The EV-P uses photoelectric detection with ASIC technology in a low profile, compact design. It has low monitoring current, an Omniview 360° LED fire alarm indicator, a remote indicator output and a base control auxiliary output, and non-polarised terminals for installation. It complies with EN54-7:2000 + A1:2002.

Detector with a sounder

The EV-PYS photoelectric optical detector has a built-in sounder with an output of about 88dB(A) at 3.5mA and a 360° LED indicator. It needs one address, which simplifies installation and reduces time, and it complies with EN54-3:2001 and EN54-7:2000.

Multi-sensor detection

The EV-PH houses an optical smoke sensor and a 54°C A1R heat sensor together. An algorithm processes the optical and heat signals at the same time to minimise false alarms, so the detector can respond to smoke and to heat. The EV-PH uses Nittan Evolution FSK communication with EEPROM addressed programming. It complies with EN54-5 and EN54-7.
