TRUEALARM ADDRESSABLE FIRE DETECTION

TrueAlarm multi-sensor 4098-9754 combines the TrueAlarm photoelectric smoke detector with a fast-acting and accurate TrueAlarm thermal sensor to provide both features in a single sensor/base assembly. Analog information from each sensor is digitally communicated to the CIE where it is analysed.

The 4098-9714E Photoelectric smoke detector contains a state-of-the-art sensing chamber and analog communication electronics. Used with the 4100 CIE, the 9714E has a high degree of false alarm immunity thanks to advanced algorithms. The detector mounts on the 4098-9789 addressable base or 4098-9794 sounder base.

The 4098-9717E Ionisation detectors use a single radioactive source with dual sampling chambers to provide stable operation under changes in environmental conditions eg., temperature and humidity.

The VLC600 TrueAlarm LaserCOMPACT detector has been specifically designed to provide all the benefits of aspirating smoke detection in small areas where space is at a premium. The VLC600 communicates directly with the CIE.

TrueAlarm heat detectors are self-restoring and provide rate compensated, fixed temperature sensing, selectable with or without rate-of-rise temperature sensing. Due to its small thermal mass, the detector accurately and quickly measures the local temperature for analysis at the CIE.

TrueAlarm detector bases contain addressable electronics that constantly monitor the status of the detachable detectors. Each detector’s output is digitised and transmitted to the CIE every four seconds. Since TrueAlarm detectors use the same base, different detector types can be easily interchanged.

The TrueAlarm sounder base has a built-in Piezoelectric sounder that provides a high 90dBA output with a low 17mA current. Used with the interchangeable TrueAlarm detectors the sounder can be powered from 24 VDC or from a compatible Notification Appliance Circuit NAC and synchronised coded/temporal coded by communications or by the NAC.

The 4098-9793 isolator base accepts TrueAlarm analogue sensors and provides communications isolation to improve installation convenience and increase system integrity. An internal isolation relay allows a compatible CIE to separate shorted communications wiring from functioning wiring to optimise the available sensors or other IDNet addressable devices.

This surface mounting IDNet Manual Call Point has a plastic coated frangible element to ensure safe and reliable operation, producing no dangerous glass shards. The 4099-9701 is operated by simply pressing on the centre of the frangible element until it snaps. The snapped frangible element releases a microswitch, which signals an alarm at the CIE.

The 4098-9755E True Alarm Duct Sampling Unit detects the presence of smoke in air conditioning or ventilating ducts. Sampling tubes are installed into the duct and air is directed to a smoke sensor mounted in the housing.
