Smoke sensor APC NBES0307 — standalone photoelectric detector, 130.2×170.5×168.8 mm

APC Smoke Sensor NBES0307 is a standalone photoelectric smoke detector designed to identify visible smoke particles in enclosed spaces. With compact dimensions of 130.2×170.5×168.8 mm, this unit is intended for residential areas, small commercial premises and IT spaces where early indication of smouldering or flaming fires is required. The device operates independently and can supplement existing life-safety systems to provide an additional layer of smoke detection and rapid notification of potential fire events.

Advantages

The photoelectric sensing principle provides reliable detection of visible smoke from slow-smouldering fires while reducing false alarms from normal cooking or steam. Its standalone design simplifies installation where full fire panels are not required, and the compact housing fits into corridors, rooms and equipment racks. The sensor is suitable for monitoring IT cabinets and small server rooms, and it is supplied with accessories for flexible mounting options.

Suitable for

• Residential rooms and hallways
• Small office and retail spaces
• IT closets, server racks and equipment cabinets
• Corridor and common-area monitoring
• Supplementing existing life-safety systems

How to use

Install the APC Smoke Sensor NBES0307 in a central location within the protected space, avoiding corners and areas near ventilation grilles that could interfere with airflow. Follow manufacturer guidance for mounting height and orientation appropriate to the chosen location (ceiling or wall); use the supplied rack-mount brackets and cable ties when installing inside equipment racks. Connect power and any required monitoring or alarm interfaces according to site wiring practices. Test the detector after installation using the test method recommended by the manufacturer to confirm proper operation.

Usage recommendations

Position detectors to provide early detection of smoke-generating events, keep them clear of dust buildup, and perform regular functional tests and periodic cleaning. For IT spaces and server cabinets, place sensors near probable sources of heat or smoke but away from forced airflow that could delay detection. Consider combining standalone detectors with centralized alarm systems for coordinated notification and response.
