Extinguishing Control Panel
Installation and Operation Manual
Page 17
When using the control panel, press the
Start
key corresponding to the
alarming zone on the control panel to start extinguishing devices, and output
starting level. Since the holding period for starting level is the same as the
time you press the start key for pulse output mode, you will have to keep
pressing the start key until gas starts to release.
When using the FACP, there are two methods: from the keypad and from
fireman’s control panel. When the “start” key on main unit (input the
addresses of the extinguishing devices and confirm) or the key on manual
start panel is pressed, the FACP sends out start command immediately.
Using the “start” key on the keypad is a common method, which requires user code
and types of connected extinguishing device
s; using fireman’s control panel is a
special and quick method. It requires programming and defining the manual keys on
fireman’s control panel and their corresponding extinguishing devices when
commissioning the FACP
. When giving start command by fireman’s control panel,
press the manual key, command LED will be lit and start command will be sent out.
Generally, it
’s recommended to use fireman’s control panel as a quick method less
possible to be mistaken. By this method, you can simply find the corresponding unit
according to the indication on the keys of the fireman’s control panel and then press its
command key. Under special conditions, if the devices cannot be started through
fireman’s control panel, they can also be started through keyboard.
Note:
As soon as the immediate start command is given, extinguishing
devices will finish release instantaneously without a stop choice, so this
operation
should be carried out with caution.
For pulse output mode, the holding period for starting level is the same
as time you press the start key. In other words, you will have to keep
pressing the start key until gas starts to release or for more than 5
seconds.
For level output mode, output circuit can be instantly self-locked to keep
continuous output, you only need to press the key for about 1 second.
To reset the output, you will have to turn off the 24V power of the control
panel.
The start command must be given under “Manual Enable” and “Release
Enable” states either you start the controlled devices through the
keypad
or through fireman’s control panel of the FACP. When the FACP
is in “Manual Disable” or “Release Disable” states or the device to be
started is disabled or in fault state, the start operation is invalid.
To start immediately, you need to press the central part of the protective
cover, as shown in Appendix 3.
b) Delay Start
Delay start mode enables the user to confirm if fire really occurs, and if people in the
protective zone have been evacuated during the delay time to ensure safety of life and
property.
