System Configuration
The detectors and call points are arranged in zones to enable the approximate location of a fire alarm to be
identified. The number of zones depends on the size and the layout of the premises, and is limited to 8 zones
per control panel. There should be a chart or drawing provided with the system indicating the area and layout
of the zones – ensure that you are familiar with the zone layout so that appropriate action can be taken in the
event of a fire alarm.
The control panel display may also give you a zone number, a zone description and a device type for the
device which has operated.
The system may be interfaced with the building services, e.g., the air conditioning may be shut down when the
alarm sounds. Make sure that you know what happens when the fire alarm operates as this can affect routine
system testing.
The TWINFLEX
®
pro control panel also incorporates an integral power supply unit with charger and requires
2 x
12V 3.3Ah batteries
to provide up to a maximum of 72 hour standby times, depending on total panel loading.
Unlike most conventional fire alarm systems, which require separate pairs of cables for detector zones and
sounder circuits, the TWINFLEX
®
pro system requires one 2-core screened cable for each zone to
accommodate both detection devices and sounders. Furthermore sounders are incorporated within the
detector to reduce system components and simplify installation.
What to do if . . .
The fire alarm sounds;
CARRY OUT THE PRESCRIBED FIRE DRILL
When it is safe to do so silence the alarms and reset the system, having first established the cause of the
alarm (refer to Operation).
The buzzer sounds;
If the buzzer sounds without the alarm sounders operating it is likely to be a fault or other abnormal condition.
Make a note of
all
illuminated LEDs and displayed messages, record the time that the condition occurred (if
known), and other events within the building, eg., power failure, contractors working, etc., (Refer to
troubleshooting). Call the service company with as much information as possible.
