The NS-AOHS-IS has 2 separate analogue sensor elements. One optical element for smoke detection and one heat-sensing element for heat detection.
An alarm is indicated on the NS-AOHS-IS via a red LED. The LEd will remain lit, until the alarm has been reset on the fire alarm panel.
The address is set with a DIP switch, which is mounted on the backside of the detector.
NS-AOHS-IS is connected to the detector loop via the ISOLATOR-A, part. no. N1790. Up to 20 addressable IS units can be connected to one ISOLATOR-A. It is not possible to connect any remote LED indicator to NS-AOHS-IS.
