Salwico NS-AH/A1S Heat Detector (N11231)


The Salwico NS-AH/A1S (N11231) is an analogue addressable Heat Detector that is for use in addressable Fire Alarm Systems. The NS-AH/A1S has a pre-programmed static alarm level of 54°C and also gives a rate of rise pre-alarm.

The low profile Heat Detector uses a high quality electronic sensing element of low thermal mass, which gives a very accurate and fast temperature reading. The temperature can be displayed on the Fire Alarm Panel. When the Salwico NS-AH/A1S is in alarm condition, a red LED on the Detector will be lit. The LED will remain lit until the alarm has been reset.
