Reflected beam smoke detection.
Projected beam photoelectric smoke detector.
System sensor model 6424 projected beam smoke detector is uniquely suited for protecting open areas with high ceilings where conventional spot type smoke detectors are difficult to install and maintain.
General description system sensor model 6424 is a long range projected beam smoke detector designed to provide open area protection.
The light transmitter emits an unseen beam of light that is received by a receiver in the usual condition.
An optical beam smoke detector is a device that uses a projected beam of light to detect smoke across large areas typically as an indicator of fire.
From smoke detectors like photoelectric smoke detectors projected beam smoke detectors and ionization smoke detector to heat detectors such as rate of rise and fixed temperature heat detectors.
Whether it be a smoldering fire or a flaming fire you ll want to be aware as soon as possible.
For example photoelectric smoke detectors are well known for protecting against smoldering fires.
It is to be used with ul listed separately supplied power 4 wire control panels only.
The two most commonly recognized smoke detection technologies are ionization smoke detection and photoelectric smoke detection.
With only one device to install and align these single ended optical.
Listed for operation at the broad est temperature range in the industry 22 f to 131 f the 6424 can be used in.
Unlike traditional detection systems reflected beam smoke detectors were designed for spacious rooms open areas and high ceilings.
The other three being projected optical beam aspirating and video smoke detection are generally used for specialist applications.
Ionization smoke alarms are generally more responsive to flaming fires.
They are used to detect fires in buildings where standard point smoke detectors would either be uneconomical or restricted for use by the height of the building.
Ionization type smoke alarms have a small amount of radioactive material between two electrically charged plates which ionizes the air and causes current to flow between the plates.
Optical beam smoke detectors are often installed in warehouses as a cost effective.
Photoelectric smoke alarms are best at detecting smoldering fires while ionization smoke alarms are better at detecting sudden fast burning fires.
Before we go on to explain the operation of the ionisation and photoelectric smoke detectors it is important to explain the inherent features of the overall design of the detector enclosure.
Experts say photoelectric smoke detectors generally won t cause as many false alarms but for the ultimate in safety they recommend opting for a smoke detector with both types of sensors.
Their innovative features make them popular choices for spaces like warehouses atriums arenas and churches.
At first alert we want to make sure you understand the technology that helps keep you safe so you can make the best decision when it comes to.
