Dry areas, store rooms etc are unattended areas.If fire breaks in these areas , it doesn't get noticed & can cause major fire hazards. If a Smoke detector alarm is installed in unattended areas, an alert is generated in time & major fire hazards can be prevented.Household fires due to cooking gas leakage or electrical short circuit are not uncommon. Generally, there is no smoke without fire. As the damage caused by fire accidents is catastrophic, it is necessary to continuously monitor to detect any smoke before the fire spreads to other parts. It allows for evacuating people in time & take immediate countermeasures as well. Now ensure the protection of your loved ones as well as your property from fire. Use Smoke Detector Alarm: GUARDIAN-3 with dual Sensor. The optical gas sensors invariably employed in most of smoke detector/alarm, works based on the light scatter principle & have limitations. They fail to give an early warning or can give false alarm causing a nuisance. Guardian-3 has an additional highly sophisticated electronic sensor, specifically tuned for detecting smoke. The sensor voltage variations are continuously monitored by a Microcontroller brain, unlike other devices in the market which incorporate just a comparator IC. The highly reliable Micro Controller with inbuilt intelligence analyses smoke levels for deciding the course of action. Too much sensitivity can cause a false alarm. Hence most of the devices in the market are tuned to respond to a higher % of smoke in the air. As a result, the alert process is delayed, causing a loss of precious time. Guardian-3 has a Three Level Audio Visual Alarm. At the slightest detection of smoke, it alerts by just blinking a Red LED, if the smoke level increases it sounds Piezo Buzzer to draw attention for corrective action & if the smoke level is too high it sounds a very Loud Alarm. In case of very high smoke levels, the Loud Alarm sounds instantaneously. Thus you are alerted well in advance without causing panic. The alarm can be silenced only if the smoke contents in the air fall down to a safe level. Guardian-3 does not require any periodic monthly testing as an Autotest is carried out every 2 minutes.
