The Salwico ACP-IS is a intrinsically safe addressable manual call point. It is used for the fire alarm systems CS3000, CS4000 and NSAC-1. Up to 20 addressable IS units can be connected to an ISOLATOR-A. Pressing the glass causes it to crack and activates the fire alarm. A test key can be used to test the device.
A red LED on the manual call point indicates the fire alarm. When the push button is pressed the red LED will lit and it will remain lit until the alarm on the central panel is reset.
