The Nittan NS-AH/A1S is an analogue heat sensor, supplied here together with the NS-Adapt-IS2 detector base, for use in a ship’s fire alarm system. It monitors temperature across an analogue range of -25 °C to 90 °C and signals a fire condition when heat builds up in the protected space. Rated at 24 V DC, it draws 0.2 mA in normal state and 2.5 mA in alarm, with a 2 mA remote output. The set is marked 095045 and was made in England. Both items are in used condition.
