This document details the user information for the Protec Cirrus Hybrid Aspirating Smoke Detector with specific attention to the basic system operations of the product. The Protec Cirrus Hybrid Aspirating Smoke Detector has been designed and manufactured in the United Kingdom and complies fully with current standard dictating aspirating smoke detector design practice (EN54 parts 20).
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.
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.
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.
Providing ‘timezone’ is enabled, the home page will display indicate the pipe night mode is activated. Silence and reset The Cirrus Hybrid is fitted with an internal buzzer. The buzzer will sound when the unit is in Fault, Pre- alarm or Fire. Buzzer parameters...
The network menu displays: Protec Loop serial number. Protec address for each pipe assigned by the Protec fire panel IP address, Subnet Mask and Gateway either automatically assigned by network or manually inputted as a fixed address.
Click again to toggle between event log, realtime and historical graph. The Cirrus Hybrid stores all fire, faults and events in the event log. The event log can store a maxium of 256 events. In the user access level 16 latest events are viewable.
Fire When a fire alarm condition is activated the Cirrus Hybrid unit will display the pipe text of the pipe in alarm and the fire alarm level (1, 2 or 3) in the ‘detector status’ list. The fire alarm level LED will illuminate and the buzzer will pulse (fast).
Check the device in fault is fitted correctly otherwise contact a Protec operative or a Protec distributor. 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.
The unit has detected that insufficient light is being received at the photodiode. User Action Contact a Protec operative or a Protec distributor. Water fill fault The unit has detected that the water fill value level reading out of range.
6.22 Battery A monitored input set up for External Battery Fault has detected a fault. User Action Check the power supply equipment and wiring if the fault persists contact a Protec operative or a Protec distributor. N93-601-00 Issue 1 Page 21 of 25...
6.23 Mains A monitored input set up for Mains Fault has detected a fault. User Action Check the power supply equipment and wiring if the fault persists contact a Protec operative or a Protec distributor. 6.24 Pipe Scan Halted The pipe hold function forces a scanning unit to sample from the selected pipe. While unit is in this state it will display a ‘Pipe Scan Halted fault’, until the pipe hold function is disabled.
Events The Cirrus Hybrid stores operational events within the internal memory ‘event log’. The following events are logged. Processor Fault The internal processor hardware has unexpectedly reset. Power Up The unit has powered up, occurring on first power, unstable supply voltage or after an undesired reset.
(<50% R.H) or high ambient temperature (>30C) conditions will increase the water usage. 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: ...
