5.4. QUIESCENT (SUPERVISION) MODE
In the quiescent mode, i.e. when the control panel waits for a signal from fire warning devices, only a
green colour POWER (6) diode is lit on the front panel informing that the control panel is power
supplied. Additionally, the LCD (5) displays the current time and date.
General fire alarm relays and zone relays are inactive and the general fault relay is in an operating
mode.
5.5. ALARM MODE
5.5.1 Fire alarm signalling
The following indications can be seen on the control panel front side during the fire alarm:
-
one of the ZONE 1…24 red zone indicating diodes switches on; the first zone where a fire has
occurred is distinguished with flashing light, all others are lit with steady light;
-
the general alarm display, with a FIRE communique, flashes;
-
a fire alarm message, indicating the zone number where the first alarm occurred
and the elapsing time remaining until general fire alarm relays are activated, appear on the
LCD;
-
an internal acoustic signalling device is switched on, operating with an interval of 0.5 s/0.5 s
signal.
The acoustic signal (internal and external) can be silenced at the 1
st
access level by pressing the
ACKNOWLEDGEMENT push button (option 0) or only the internal one (option 1). The 1
st
stage alarm
duration can be programmed in the 0…10 min. range and its countdown can be stopped by the
transmission disablement with the help of the TRANSMISSION push button (2
nd
access level). Lack of
the 1
st
stage alarm acknowledgement shortens the delay time to 30 seconds. After the delay time
elapse (without transmission disablement), the control panel evokes the 2
nd
stage alarm.
5.5.2 Fire alarm verification by the attending personnel
The control panel enables an occurrence verification by the personnel in case a fire alarm has been
revealed. It is required that the attending person approaches the panel and confirms an alarm
receipt within 30 seconds by pressing the ACKNOWLEDGEMENT push button. In case the person on
duty fails acknowledgment within the given time period, the control panel initiates an alarm
transmission outside without any delay, i.e. to a monitoring centre or to the fire brigade. After the
fire alarm receipt acknowledgment, the person on duty is given an additional time, with a
programmable length, for recognition of a real fire threat in the premises.
The elapsing time left for the alarm acknowledgment and for the threat recognition is displayed on
the LCD (5).
In the case of a false alarm or when a threat does not exist, the person should reset the light signal
with the RESET push button. This operation is effective when no fire factor is present in the vicinity of
the fire warning device that has evoked the alarm and the 2
nd
access level is available.
5.5.3 Automatic alarm signal verification, alarming variants
The control panel possesses a wide range of possibilities to verify fire signals coming from fire
warning devices. Recognition of a received signal as a fire alarm is preceded by multiple checking
readout and analysis of the signal received from the detection lines. Moreover, it is a possible to
program the following alarm variants for every detection line:
•
one-stage alarm;
•
two-stage alarm;
