Intrinsically Safe analogue photoelectric smoke detector

The IS analogue photoelectric smoke detector 2840 is connected to the c.i.e. via an IS barrier unit 2842 (IS COM line) and programmed via Win128 / Win512 / WinG3 or EBLWin as an Analogue photoelectric smoke detector 4301, i.e. it takes one COM loop address. In principle, the 2840 is a 4301 smoke detector but with a different housing, IP rating etc.

The COM loop address is set in 2840 with the address setting tool 3314/4414 in NORMAL mode. The sensitivity level is dependent on the selected alarm algorithm, i.e. the same algorithms as for the 4301 detector. The detector has one built-in LED to indicate that the detector has generated a fire alarm. The detector can be mounted with or without the water-proof IS back-box 2843, which has two cable glands (½").
