4.3.4 Two - wire detectors
In Figure-8, Annex. A ; a sink current detector
’s connection is shown. Appropriate jumper settings should
be selected.
4.3.5 Three - wire detectors
In Figure-9 Annex-A; a 3-wire detector
’s connection is shown. Appropriate jumper settings should
be selected as sink or source.
4.3.6 Flame detectors
Jumper settings are adjusted according to detector is sink or source. Definitely do not select fire settings
4.4 Remote control inputs
Some of controls of gas alarm control panel can also be done remotely. These are:
·
Alarm Silence / Reset - As/R:
In case of alarm, to silence the sounders, switch is closed for one time.
If it is closed again, alarm situation is reset and system turns back to its initial position.
·Inhibiting All Channels - Inh:
Inhibits all channels. In this case panel keeps tracking detectors. Yet, if
there is an alarm from any fire or gas detectors, it shows the situation only from LCD panel.
Connections should be as in figure- 7 Annex. A. Screening table should be used.
5- PANEL OUTPUTS
5.1 Sounder outputs
The panel has 2 sounder outputs, each rated 24V DC 500mA. Current consumption more than 500mA will
cause a fault condition in sounder line. Sounder circuits are continuously monitored for open and short
circuit faults by connecting the end of line resistor on the last device on the circuit. 2x1.5 mm
² cable
should be used for cabling of sounder outputs. Connections should be made according to Annex-A
Figure-4. Polarised type sounders should be used. Otherwise, fire alarm control panel displays a fault
condition.
5.2 24V DC Power Supply (Aux) Output
The panel is equipped with an auxiliary 24V DC 500mA power supply output. The output is used to
energise external devices such as telephone dialler or gas detector. Overloading the output will cause
device malfunction or output fault respectively. Connections should be made according to Annex-A
Figure-5.
5.3 Relay Outputs
Panel has 4 volt free changeover relay outputs rated 1A at 30 V DC. These volt-free outputs, high alarm
relay (normally de-energized), low alarm relay (normally de-energized), over-range relay (normally de-
energized) and fault alarm (normally energized) relay. Connections should be made according to Annex-A
Figure-6.
5.3.1 Low alarm relay:
Low alarm relay is activated when the detectors channel low limit
value exceeds in the medium. Features of low alarm relay; threshold, latching/non-latching, NO/NC
operating is adjusted by the user.
5.3.2 High Alarm relay:
High alarm relay is activated when the detectors channel high limit
value exceeds in the medium. Features of low alarm relay; threshold, latching/non-latching, NO/NC
operating are adjusted by the user.
If channels include conventional fire alarm detectors, when detectors sends fire alarm signal, high
a
la
rm relay will be activated.
5.3.3 Over-range Relay:
If the gas level in the medium exceeds a fixed high limit (21.5 mA),
over- range relay is activated. Latching/non-latching, NO/NC operating is adjusted by the user.
