GST I-9105R Reflective Infrared Beam Smoke Detector

Summary

The I-9105R is a reflective infrared beam smoke detector that may be used in either addressable or conventional operating modes. Being microprocessor based, the detector offers extensive algorithms for analysis and decision making. Taking ambient operating conditions into consideration, system adjustments such as drift compensation and alarm and fault analysis are automatic. The sensitivity of the detector is adjustable to suit various application conditions.

Installation

The number of reflector in a system is varied depending on the required operating distance (range) of the detector. Optical reflectors from 1 to 4 provide an effective range of the detector between 8 and 100 m. These are supplied with the beam. The address (when used in a GST addressable application) as well as the operating modes and sensitivity of the I-9105R is programmed with the standard GST hand held programmer (P-9910B).

Operating Modes

Addressable Mode

When connected with an addressable GST fire alarm control panel (CIE), the I-9105R automatically switches to addressable mode and reports its information through the addressable loop. In addressable mode its address may be configured between 1 and 242 as is common to with all GST addressable devices.

Conventional Mode

When the I-9105R is not connected with an addressable GST CIE, the detector automatically switches to conventional mode. In conventional mode fire and fault information is reported via potential free contacts.

Applications

The I-9105R is particularly suitable for use in historical buildings, warehouses, large storage areas, shopping malls, leisure centres, exhibition halls, hotel lobbies, printing houses, clothing factories, museums and prisons.
