Description
NS-AOHS-IS is an intrinsically safe analogue addressable
multi sensor detector for Salwico fire alarm systems.
It has two separate analogue sensor elements. One optical
for smoke detection and one heat-sensing element for heat
detection.
Alarm condition is indicated on the detector via a red
LED. The LED is lit until the alarm has been reset on the
control 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.
