3.0 Cirrus Hybrid General 3.1 Introduction The Cirrus Hybrid utilises both Cloud Chamber and Scatter Chamber detection technology to monitor for Fire and Smoke through an aspirating pipe system. These two technologies are used together to combine the best attributes of each technology in an algorithm based system. 3.2 Cloud Chamber It is known that particles smaller than the wavelength of visible light occur spontaneously as a material is overheated, and in numbers far above those present in a normal ambient environment. Cirrus Hybrid utilises the Wilson Cloud Chamber principle to detect the sub-micron particles that are generated at the incipient, and all other stages of fire. A filtered air sample is delivered to the detector via a centrifugal blower, a portion of which is diverted into a humidifier. At approximately 100% relative humidity, the sample is directed to the Cloud Chamber where, because of cooling, due to rapid vacuum expansion, water condenses onto the small particles and forms a cloud. Consequently, the thermally generated particles cause many droplets to form into the cloud, which is then detected by the measuring system of the Cloud Chamber. The density of the cloud being proportional to the number of particles present. The result is a continuous signal that corresponds to the particle concentration. This signal is used to provide a staged alarm sequence with four alarm levels. The Cirrus Hybrid is a self-supervised system that continuously monitors for correct operation. Any problem is immediately reported on the front panel display, buzzer and the operation of a Fault relay. The Cirrus Hybrid locally stores fault data, background particle concentration and event data. These can be accessed from the Menus.

3.3 Scatter Chamber Detector The Scatter Chamber Detector (SCD) operates by measuring the light scattered by the air within the scatter chamber. A photo sensitive sensor element is placed in a dark chamber with a high brightness light source that cannot be seen by the sensor. When smoke is present the light is scattered in all directions, some of which is detected by the sensor and relates to the amount of smoke present. The scatter chamber detector in the Cirrus Hybrid is very sensitive, many times more than that of the point detector and so can be used in an aspirating system which has considerable dilution from clean areas. 3.4 Hybrid As scatter chambers are as sensitive to dust as they are to smoke, the hybrid system utilises the cloud chamber as the primary detector which is not affected by dust with a boost signal when the scatter chamber detects the smoke. Using the two technologies allows the Cirrus Hybrid to make the fire decision even earlier whilst minimising the detection of false alarms. The features of the Protec Cirrus Hybrid Aspirating Smoke Detector are: Incipient fire detection via Cloud Chamber Common Fault output contact Detector technology 5 Programmable output contacts High performance optical smoke detection 3 Programmable input contacts via Scatter Chamber Detectors Airflow monitoring per pipe channel Up to 4 detection areas Variable blower speed control LED status indication; to indicate supply healthy, fault, pre-alarm and fire 7 Full colour LCD touch screen display for fault reporting and ease of setup Protec addressable protocol Commissioning menu; access code protected On-board short circuit isolator Remote network via TCP/IP N93-601-00 Issue 1 Page 7 of 25 Protec Fire Detection PLC 2015

8.0 Maintenance Maintenance service visits are dependent upon the type of application environment. For example a unit installed into a dirty environment will require more frequent maintenance then a clean environment. All maintenance should be carried out by a suitably trained and qualified person. 8.1 Cloud Chamber Water Requirements Distilled water only, replenished as required, dependent upon environment. Low ambient humidity (<50% R.H) or high ambient temperature (>30C) conditions will increase the water usage. 8.2 Periodic Checks and Maintenance The Cirrus Hybrid continuously adjusts its monitoring functions by means of feedback loops, ensuring a minimum of maintenance. To ensure continued correct operation, the system must be checked: Daily by the User. Every three months by Protec Fire Detection or an authorised representative. Whenever building alterations have been performed which could affect the system's operation. Whenever equipment within the protected area has been altered which could affect the system's operation. During a fault condition. After any alarm condition. The following are based on average conditions. Because of the wide range of possibilities in various applications, the frequency of periodic checks and maintenance may have to be adjusted accordingly. 8.3 Daily Checks The following must be performed EVERY DAY by the system User: Check system indicates a healthy condition. Any fault indicated should be recorded in the system logbook and investigated. Determine the extent of the fault and decide whether special actions (such as fire patrols) are needed. Check that any faults reported previously have been attended to. N93-601-00 Issue 1 Page 24 of 25 Protec Fire Detection PLC 2015
