What is high sensitive smoke detector?
High Sensitivity Smoke Detection (HSSD) is the most sensitive form of smoke detection on the market. It is designed to give very early indication of an emerging fire condition. This pre-emptive warning provides the time necessary to take corrective action and avoid the danger that a fire can cause.
How sensitive is a smoke detector?
The photoelectric types of smoke detectors are very sensitive to the fuming fire that emits large-sized smoke particles. On the other hand, ionization smoke alarms are sensitive to the flames fire that emits small-sized smoke particles.
What is a Vesda unit?
VESDA Systems are aspirating smoke detection used for early warning applications where response to a fire is critical. The VESDA detectors are able to communicate this information to a fire alarm control panel, a software management system or a building management system via relays or a High Level Interface (HLI).
Does a sock cover a smoke detector?
Does covering a smoke alarm with a sock work? Sure, the sock won’t get rid of the smell but at least you won’t have to face the embarrassment of setting off the fire alarm and paying a fine. Also the sock can be a key piece of decoration to let everyone else who comes into your room know that you smoke.
What does a VESDA do?
VESDA Systems are aspirating smoke detection used for early warning applications where response to a fire is critical. VESDA® works by continually drawing air into the pipe network via a high efficiency aspirator. A sample of this air is then passed through a dual stage filter.
When is a VESDA system required?
When you have a fire emergency, you need as much warning as possible to protect lives and property from harm. The VESDA system is a “very early warning aspirating smoke detection” and is designed to alarm you to the danger as soon as possible.
What is the least sensitive smoke detector?
The least sensitive is the heat detector, that will not go off because of smoke or other dense gasses at all, but will go if it senses the heat from an actual fire underway.
What do you need to know about smoke alarms?
A closed door may slow the spread of smoke,heat and fire.
What is VESDA smoke detection?
A VESDA “Aspirating Smoke Detector” or Air Sampling Device (ASD) actively evaluates the air in a protected space by drawing it through a pipe network that samples for smoke, foreign particles, gases, fumes, etc.
What is the frequency of a smoke detector?
Conventional smoke alarms operate at a high frequency of 3,100 Hz. The SafeAwake smoke alarm aid emits a low frequency (520 Hz), high decibel, square wave sounding alarm and an intermittent tactile signal to a bed shaker located between the mattress and bed springs at chest height.
What is smoke detector verification?
Alert family members that you will be testing the alarm.
