What Is System Sensor?

System Sensor is a brand under Honeywell, a global leader in security and alarm systems. The brand specializes in developing technologically advanced fire safety devices such as:

• System Sensor smoke detectors
• System Sensor heat detectors
• System Sensor duct detectors
• System Sensor beam detectors
• System Sensor carbon monoxide detectors
• System Sensor horns and strobes
• System Sensor control panels

Each device is engineered for smart sensor technology that improves performance, reliability, and seamless integration into fire alarm monitoring and notification systems.

Types of System Sensor Devices

1. System Sensor Smoke Detector

These detectors provide fast and accurate identification of smoke particles using photoelectric sensing or multi-criteria detection. Ideal for early warning detection and false alarm reduction, they’re widely used in both residential and commercial settings.

2. System Sensor Heat Detector

Engineered for areas where smoke detection may not be ideal (like kitchens or boiler rooms), these heat detectors respond to temperature thresholds or rate-of-rise conditions.

3. System Sensor Duct Detector

Installed in HVAC systems, these units detect smoke in air ducts to prevent the spread of fire through ventilation.

4. System Sensor Beam Detector

Used in large open areas like warehouses, beam detectors project a light beam and trigger alarms if smoke disrupts the beam.

5. System Sensor Carbon Monoxide Detector

These devices offer reliable CO detection, crucial in preventing poisoning in homes, schools, and commercial buildings.

6. System Sensor Horn and Strobe

System Sensor horns and strobes serve as fire alarm notification appliances, providing audible and visual notification during emergencies. Many units are UL-listed and suitable for indoor and outdoor use.

7. System Sensor Control Panel

Centralized units that manage signals from all detection devices. These are vital in automatic fire response systems, providing command and control functionalities.

How does a System Sensor smoke detector work?

System Sensor smoke detectors work by sensing particles of combustion in the air using either photoelectric or ionization technology.

• Photoelectric detectors use a light beam; when smoke enters the chamber, it scatters the light and triggers the alarm.
• Ionization detectors use a small radioactive source to ionize air; when smoke disrupts this flow, it triggers the alarm.
  Many System Sensor models also integrate heat and carbon monoxide detection for intelligent multi-criteria sensing.

Major Components of System Sensor

System Sensor devices typically include the following components:

1. Sensor Chamber – Either photoelectric or ionization, depending on the model
2. Heat Sensor Element – Thermistor for fixed or rate-of-rise detection
3. LED Indicator – For alarm status and diagnostics
4. Integrated Sounder or Horn (Optional) – For audible notification
5. Mounting Base – With terminals for wiring connections
6. Communication Interface – Addressable or conventional signaling
7. Test Switch or Magnet Test Port – For manual functionality checks
8. Backup Battery (in standalone models)
9. Tamper-resistant Locking Mechanism
10. Relay or Control Module (in advanced models) – For system control functions

Requirement of System Sensor

To ensure proper functionality and compliance, the following requirements must be met:

• Power Supply: 12V or 24V DC depending on the model
