The Consilium NS-AOHS-IS (Part No. N11250) is an intrinsically safe (IS), analogue addressable optical smoke and heat multisensor detector designed for hazardous (potentially explosive) environments. It is used with Consilium/Salwico fire alarm systems on marine, offshore, and industrial installations.
Features
- Detects both optical smoke and heat.
- Either sensor can trigger an alarm.
- Smoke or heat sensing can be temporarily disabled individually for maintenance.
- Designed for hazardous areas where intrinsically safe equipment is required.
- Connects through an intrinsically safe isolator; a remote LED indicator is not supported.
