Inputs
Class Change
A pair of terminals are provided for class change. By shorting these terminals together (e.g. switch,
time clock) the alarms will sound. The panel will not indicate a fire. The alarms will cancel when the
short circuit is removed. If the short circuit is not removed the Alarms will NOT cancel.
WARNING:- NO VOLTAGE SHOULD BE APPLIED TO THIS INPUT.
Zones
MF400 provides 4 zones & MF200 provides 2 zones . The maximum number of detectors per zone
line is 20 and end of line resistors must be fitted for correct operation.
Manual call points used in the system are polarised. Use the connection details accompanying the
call points to ensure the correct polarity is used, using the terminal marked '9300'.
Detectors used in the system are polarised 24V Menvier detectors. They must be wired in
accordance with instructions accompanying the detector. Use the terminal marked '9300'.
Outputs
Auxiliary DC Output
A 24Vdc output is provided. This output is protected by a fuse which is monitored for rupture. This
output can be to used to power fire or fault auxiliary equipment. Equipment must be connect to this
output so that current will only be drawn from this output when a fire condition exists or when no fault
exists.
WARNING:- DO NOT EXCEED THE RATED OUTPUT CURRENT
Auxiliary Fault Output
This is a 'solid state' semiconductor switch which is normally operated with no fault present and de-
activates when the panel detects a fault. It operates by providing 24Vdc which can be connected
directly to a 24V auxiliary device (e.g. relay) and a pull down switch to 0V. It is current limited to
10mA.
Remote Signal Output (Auxiliary Fire Output)
This is a 'solid state' semiconductor switch which operates when the panel detects a fire. It operates
by providing 24Vdc which can be connected directly to a 24V auxiliary device (e.g. relay) and a pull
down switch to 0V. It is current limited to 10mA. 'Class Change' and 'Sound/Silence' do not operate
this output.
Alarms
Alarm outputs are provided. ONLY polarised and suppressed equipment should be used.
Ensure the polarity of the connections are observed at all times and end of line resistors are fitted for
correct operation.
The maximum alarm load is specified in the Technical Specification section.
Alarm devices should be spread equally across the 2 alarm circuits.
WARNING:- DO NOT EXCEED THE RATED OUTPUT CURRENT.
Options included within this panel which are not required by EN54 are, Class Change, Remote Signal
Output and Auxiliary DC output. These options cannot be used to simulate options with requirements
within EN54.
If the panel receives a fire signal from a manual call point or detector the red fire LED will light, the
panel buzzer will sound, the alarm devices will be activated and the remote signal will also activate.
The red zone fire LED will light corresponding to the zone in fire. Any new zone in a fire condition will
light.
