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

Detector technology

4.5 Cirrus Hybrid Display

The Cirrus Hybrid uses a touch screen for its display. There are no buttons other than those presented on

the touch screen. The display is based on a scrolling webpage which initially shows the top of the page,

representing the first page or screen, known as the Home Page. The Home Page shows the Combined

Fire and Smoke (CFS) levels of all the connected pipes in a dial, in this case four pipes.

The CFS number indicates the numerical value of the particle level of both fire and smoke in the protected

area. The pre-alarm (Amber), fire 1, fire 2, and fire 3 (red) alarms points are indicated by the coloured

markers. The current status of fires and faults are shown under the Detector Status title bar below the dials.

For quick navigation there are a series of icons permanently displayed on either side of the page / screen:

6.0 Response to a Fault/s

The Cirrus Hybrid monitors various aspects of the unit to ensure the unit is operating within its correct

parameters. When the cirrus hybrid has a fault the buzzer will sound and one or more of the following

indications will be displayed. Unless otherwise stated in is necessary to contact a Protec operative or a

Protec distributor.

6.1 Device Missing

A communication problem to a device within the unit has been detected or a device has been removed

from the unit.

User Action

Check the device in fault is fitted correctly otherwise contact a Protec operative or a Protec distributor.

6.2 Device Added

A Cirrus Hybrid device has been added to the unit but the unit has not been commissioned to enable the

device. The device will NOT detect fires.

User Action

Contact a Protec operative or a Protec distributor.

6.3 Airflow Fault

The airflow reading has moved out of the accepted fault tolerance nominal value range by either an

increase or a decrease in airflow.

Select the quick navigate airflow icon to view the current airflow value. At the time

of commissioning when the pipe configurations are complete the airflow reading must

be zeroed. The Cirrus Hybrid sets the normalised zeroed value to 100%. If the airflow

reading has drifted out of the fault tolerance range an airflow fault is generated.

User Action

Check the air inlet pipes and outlet exhaust are fitted correctly with no blockages

If the fault persists contact a Protec operative or a Protec distributor.

6.4 No Water Fault

The cloud chambers distilled water reservoir is empty. The unit will continue to operate for approximately 5

days after the ‘No Water’ fault is generated.

User Action

Refill the internal water container using distilled water only. Any other water will damage the unit. Follow the

service procedure.

6.5 Chamber Seal Fault

The chamber is tested for ‘leaks’ during the power up tests. This fault does not necessarily stop the unit

functioning, but it must be attended to before complete failure occurs.

User Action

Contact a Protec operative or a Protec distributor.

6.6 Vacuum Fault

The unit has detected that the vacuum generated is insufficient to form a cloud. Check connections to the

pump, the pump operation and the pipe to sensor on the PCB and from the pump to the cloud chamber.

User Action
