Life Safety Consultants stocks new and reconditioned Edwards fire alarm parts you can install into your existing system and get a perfect match. The detector ’s on-board microprocessor measures and analyzes these signals. Fire detection is reaching new, advanced levels, designed to help save more lives. Edwards , continuing in its legacy as the inventor of the alarm bell, is the first multi-criteria smoke detector manufacturer to receive certification to the UL standard for Fire Alarm Systems UL.

This detector does not sense fires in areas where smoke or heat cannot reach the detector. Photoelectric detectors have a wide range of sensing capabilities, and are best suited for detecting slow, smoldering fires. More Buying Choices $65. This is a line in the sand for other manufactures to also bring their new compliant smoke detectors to market.

The Edwards photoelectric smoke detector is an interchangeable head and base detector with a light-scattering optical sensor. A pulsed infrared LED light source and a high-speed photodiodesensing element are housed in an omni-directional sensing chamber protected by an insect screen. Free shipping for many products! Disable the zone or system undergoing maintenance to prevent unwanted alarms.

Detectors must be tested after installation and as part of periodic maintenance. This eliminates the shortcomings of single-sensor optical and heat detection, and significantly reduces the risk of nuisance alarms. Control Panel pdf manual download. Technologies, New Delhi, Delhi. Series Fire Alarm Control Panels.

Lessen the sensitivity of the smoke detector by removing it from an area of air high velocity that can trigger an alarm. Areas of high air velocity include, for example, outside a bathroom door where steam vapor can exit during a shower, or an overly close proximity to the cooking smoke coming from an oven. When smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and activating the alarm. Download this chart on ionization smoke alarms (PDF, 9KB).

Photoelectric smoke alarms are generally more responsive to fires that begin with a long period of smoldering (called “smoldering fires”).
