Aritech DP991T 990 Series Discovery Multi-Sensor OpticalHeat

Aritech DP991T 990 Series Discovery Multi-Sensor OpticalHeatThe DP991T is an elegant slim-line opticalheat multi-sensor with high performance analogue addressable features. Compensation for sensor drift is included as part of the internal signal-processing algorithm.Operating PrinciplesThe DP991T multi-sensor detector contains an optical smoke sensor and a temperature sensor whose outputs are combined to give the final decision of a possible fire situation. The way in which the signals from the two sensors are combined depends on the response mode selected. Five operating modes provide response behaviour which incorporates pure heat detection pure smoke detection and a combination of both. The multi-sensor is therefore useful over the widest range of applications.Unique AddressingA unique patented addressing method provides simple user-friendly and accurate identification of monitor location whereby a coded card inserted in the base is read by any monitor as it is plugged in. All the electronic components are in the monitor but the location information is held in the base. Addressing errors during maintenance and service are eliminated. Pre-coded and pre-numbered address cards are also available. These address cards simplify and speed up installation and commissioning.Key Features5 Approved response modes for ease of optimisation to different environmentsRejection of transient signalsDrift compensation to ensure constant sensitivity360 Alarm visibilityFlashing LED optionFast alarm reportingEN54 approved and CPR certified

Aritech DT992 990 Series Discovery Heat Detector

Aritech DT992 990 Series Discovery Heat Detector

Aritech DT992 990 Series Discovery Heat DetectorThe DT992 is an elegant slim-line addressable heat detector that provides temperature information to the CIE. It uses a single thermistor to sense the air temperature around the detector. With its 5 operating modes it supports 5 classes of temperature detectors as stipulated by EN54.Operating ModesEvery operating mode has a different behaviour each suitable for a different application. All modes have a fixed temperature trigger with optional rate-of-rise selection allowing the detector to respond to a temperature alarm before the fixed level is reached. The DT992 supports A1R 57C with rate-of-rise A2R 61C with rate-of-rise A2S 61C static CR 90C with rate-of-rise and CS 90C static modes of operation.Unique AddressingA unique patented addressing method provides simple user-friendly and accurate identification of device location. A coded card inserted in the base is read by the detector as it is plugged in. All the electronic components are in the detector but the location information is held in the base. Addressing errors during maintenance are eliminated because the address remains in the base. Pre-coded and pre-numbered address cards are available.ApplicationsThe DT992 is ideal for use in environments that are dirty or smoky under normal conditions. It is therefore well suited installation in warehouses loading bays and car parks.Key Features5 Approved response modes for ease of optimisation to different environmentsRejection of transient signalsDrift compensation to ensure constant sensitivity360 Alarm visibilityFlashing LED optionFast alarm reportingEN54 approved and CPR certifiedApollo equivalent 58000-400

Aritech DP991 990 Series Discovery Optical Detector

Aritech DP991 990 Series Discovery Optical Detector

Aritech DP991 990 Series Discovery Optical DetectorThe DP991 is an elegant slim-line optical sensor with high performance analogue addressable features. Compensation for sensor drift is included as part of the internal signal-processing algorithm.Optical Smoke MonitorThe optical smoke detector has an internal pulsing LED and a photo-diode at an obtuse angle. In clear air conditions the photo-diode in the monitor receives no light from the LED and produces a corresponding analogue signal. This signal increases when smoke enters the chamber and light is scattered onto the photodiode. The signal is processed by the electronic circuitry and transmitted to the control equipment in exactly the same way as in the case of the ionisation smoke monitor.Drift CompensationThe drift compensation algorithm will compensate for changes in sensor output caused for example by dust in the chamber and will therefore hold the sensitivity at a constant level even with severe chamber contamination. This increased stability is achieved without significantly affecting the detectors sensitivity to fire.Compensation values are stored in non-volatile memory and will be retained even if detectors are disconnected.Unique AddressingA unique patented addressing method provides simple user-friendly and accurate identification of monitor location whereby a coded card inserted in the base is read by any monitor as it is plugged in.
