benefit and advantages using iris conventional detectors range
TRANSCRIPT
Following an example of benefits introduced from Inim technology applyed to fire detection system:
Conventional detectors…
Are the simplest and cheapest detectors
Conventional detectors are like a simple switch, they are connected on a cable all in parallel and when an alarm is detected … the line is closed…control panel signal the alarm…
With conventional detector available on the market no way to control any device parameter…
CONTROLPANEL
In case of problems or false alarm activation no means to investigate or trim something…
But with Iris «unconventional» conventional detectors…
During commissioning or maintenances operations it is possible to disconnect the detector line from panel…
…and connect it to EDRV100 driver …
EDRV100 can operate connected to a PC …
… or stand alone thanks to its internal battery

Identify each conventional detector connected on the line
And for each one…
Thanks to Versa++ technology is possible to:
Smoke Sensitivity can be adjusted
Heat Sensitivity can be adjusted
Smoke and heat combination mode can be selected :•OR Mode•AND Mode•Only Heat•Only Smoke•PLUS Mode
Red Led, Yellow Led and remote output can be manually activated
Any fault (chamber contamination, chamber fault, thermal probe fault etc) is reported
A full diagnostic of each detector is available:
Smoke chamber contamination level
Real time Smoke value graph
Real time temperature value graph
Each detector store the last 5 minutes of smoke and tempearture values before the last alarm providing a powerful tool for investigate over the alarm causes
Optical Smoke detectors are based on th eprinciple of the light scattering, to avoid false alarm it is important to avoid contaminations in the analysis chamber
Top side completely sealed to avoid dust or water condensation to reach the chamber
One of the most common false alarm or fault reason is the dust coming from the pipes or condensating water dropping from the top side
Metal mash agains insect wit less than 500um holes diameter
One of the biggest problems of optical smoke detectors is dust or insect entering in the chamber
Electronic circuit completely WAX coated to avoid any contamination
Moisture or environmental pollution may affect the behaviour of hi sensitive electronics circuits in the detector
Sensitive part of the circuit completely shielded by a metal cage
Electromagnetic noise may affect the measurement of the hi gain amplifier generating false alarms
Last generation CPU inside each detector whith hi false alarm rejection algorithm
The measurement of the smoke chamber and thermal probe are evaluated by the internal CPU and by means of the algorithm designed from the Inim R&D department an hi rejection to false alarm is achieved
Smoke chamber easy to open for clean up operations
In case of detector’s chamber contamination detector can be easily opened and cleaned with some air or a soft brush
