Discovery Ionisation Smoke Detector

The Discovery Ionisation Smoke Detector from Apollo is designed to detect fires by monitoring changes within its smoke chamber. The detector uses a low-activity radioactive foil to irradiate the air inside the smoke chamber and create a current flow.

When smoke enters the chamber, the current flow is reduced. This change is detected by the device and results in an alarm, allowing the detector to identify the presence of smoke as part of a compatible fire detection system.

Ionisation Smoke Detection Technology

The Discovery Ionisation Smoke Detector operates using an ionisation-based detection principle. A low-activity radioactive foil is used to irradiate the air within the smoke chamber, creating an electrical current.

When smoke enters the chamber, it affects the movement of ions within the air and reduces the current flow. The detector responds to this change by initiating an alarm condition.

This technology allows the detector to monitor the protected area for smoke and provide an alarm when the required detection condition is identified.

Product Features

The Discovery Ionisation Smoke Detector includes:

• Ionisation-based smoke detection
• Low-activity radioactive foil
• Smoke chamber for detecting changes in air conditions
• Current-flow based detection method
• Alarm activation when smoke reduces the current flow
• Apollo Discovery range fire detection product

How the Discovery Ionisation Smoke Detector Works

The detector uses a low-activity radioactive foil to irradiate the air inside its smoke chamber. This process creates a current flow within the chamber.

Under normal conditions, the current remains at its expected level. When smoke enters the chamber, the current flow is reduced. The detector recognises this change and generates an alarm.

This provides a straightforward method of detecting smoke as part of a compatible fire alarm and detection system.

Applications

The Discovery Ionisation Smoke Detector can be used as part of suitable fire detection installations where ionisation smoke detection is required. The appropriate detector should be selected according to the characteristics of the protected area and the requirements of the overall fire detection system.

It can form part of a wider fire safety installation alongside compatible detection, alarm, and control equipment.

Apollo Discovery Ionisation Smoke Detector

The Discovery Ionisation Smoke Detector is an Apollo product listed under the Smoke Detector category. Its ionisation technology allows the device to detect smoke by monitoring changes in the current flow inside the smoke chamber.

For installation, product compatibility and the requirements of the overall fire detection system should be considered to ensure the detector is suitable for the intended application.
