Salwico NS-AH/A1S N11231 Heat Detector Head 56°C


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 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.
