DESCRIPTION

The Ventcroft  FIRETRAX (FT2BS & FT1BS) are both fire control panels designed to comply with 
BS5839:Part 4 1988 used in systems in the detection of fire, described in this manual as 
CIE(Control Indicator Equipment). The CIE has 1 or 2 fire detection circuits(model dependent) for 
the connection of fire detection and call point devices. The CIE is powered from the mains supply 
and utilizes a backup circuit to allow the connection of stand-by batteries allowing the CIE to 
function with a mains failure.

In the event of fire detection two sounder outputs are provided to drive 24V sounder or strobe units 
to communicate evacuation, the sounder output can also be remotely triggered via the remote ring 
input. A relay provides a switchable voltage free output which changes state during a fire activation 
and can be utilized, for example to switch devices such as digital phone communicators or  to 
indirectly release power to fire door holding devices.

INSTALLING MANUAL CALL POINTS AND 

    AUTOMATIC DETECTION DEVICES

Manual Call Points must be installed before automated detection devices as 

shown below in (fig. 5.7), when using End of Line resistor monitoring. In the very last device a 6K8 
ohm resistor must be placed across the device to provide end of line monitoring. In all detection 
devices automatic or manual a 470 ohm resistor should be connected in series with its terminals 
which are presented to the CIE. 

In some installations it may not be convenient for all call points to be installed before the 
automated detection devices , in these cases an EMU (Electronic Monitoring Module) provides 
active end of line monitoring and allows the different types of detection devices to be mixed in any 
order. The EMU device must be placed in the furthest most detector. When using an EMU a 
capacitor must be placed across the zone terminals in the CIE. Shown in fig 5.8

Devices should be wired in 1mm  or greater copper cable, 

 should be no spurring or "T offs" 

from the main run.

 USING EOL (End of Line) RESISTOR  MONITORING

Resistor basses must be used, diode resistor bases must never be used as fault will not be reported.

5.8

 

USING EOL ELECTRONIC MONITORING UNIT

When using electronic monitoring devices it may be necessary to fit a capacitor in the CIE, correct polarity 
must be observed when connecting the capacitor. Diode resistor basses must be used

 ADJUSTING THE BATTERY CHARGING VOLTAGE

On completion of the installation and during regular maintenance the battery 
charging voltage should be  27.2 V dc, measured at the battery input terminals on 
TB3 14 & 15 while not connected to the battery. The battery charging voltage may 
be set by adjusting   potentiometer VR1 whilst measuring across the battery 
terminals 14 & 15 on TB3. Access to VR1 is gained from the rear of the PCB.

5.4  

INSTALLING THE BATTERY

Install the 24 V battery normally made of 2x12 V SLA 
batteries connected in series. Correct polarity connection 
must be observed. The pre installed 6K8 resistor must be 
removed before connecting the batteries.
