TFP-40x Series Conventional Fire Alarm Panels
TFP-40X INSTALLATION & OPERATION MANUAL
10
In the case that main supply is interrupted, the smart charging unit automatically opens the battery connections
and shut down the system to prolong the useful lifetime of the batteries when the battery voltage drops below
20.5V. If the main supply is restored, the batteries automatically return to charging status.
5.5
Battery Charge Voltage Check
Battery charge voltage is set at the factory as 27.6 VDC at 20°C. Therefore there is no need to readjust the
battery charge voltage. But if problems occur with battery charge, the following steps should be taken:
1
After the battery is disconnected and the panel displays the error "No Battery", no voltage should be seen at
the battery connector of the panel.
2
The front cover of the panel should be opened and device shall be taken to Access Level-3. At this level,
heat compensation of the smart charging system is deactivated.
3
The output voltage of the main supply should be checked. In this case the output voltage should be 27.75
±50
mV. If the output voltage is not at this level, the output voltage should be brought to this level via the
adjustment potentiometer located near the power supply.
4
When the adjustment of the output voltage of the power supply is completed, the panel should be brought
back to access level-1.
5
When an empty battery (~22V) is reconnected to the panel, it must be seen that voltage between the
battery poles rise rapidly. If not, there is a problem with the battery or the panel.

Inputs and Outputs
Relay Outputs:
The panel has 2 dry-contact relay output that can withstand a current of 2A at 30 VDC. These
dry-contact relays are fire relay (normally non-energized) and fault relay (normally energized).
Important Note:
The relays of the fire alarm panel are signal relays. If these relays are to operate a device
as command relays, a contactor should be place in between. If a contactor is not used when the relay outputs
are used in an application that draws high current, then the panel may be damaged and this situation is
outside the warranty scope.
Siren Outputs:
The panel has 2 siren outputs of 24 V DC 500 mA with automatic return and fuse protection.
Drawing too much current through this output causes to panel to give out faults. This output is monitored by the
end-of-line resistance against open circuits and short circuits. The cable of the siren supply line must a 2x1.5-
mm2 cable. The connections are shown in "9.2 Appendix-Electrical / Figure 6 Siren Connection.
Alarm Relay:
In case of a fire alarm from the detection zones or when the "Alarm On /Off " button on the front
of the panel is pressed, it is activated by changing contacts and is used to control another system. In order for
the active relay to be restored, the fire status has to be eliminated and the "Reset" button on the panel has to be
pressed.
Trouble Relay:
It is activated by changing contacts in case of a fault alert from the system and when the power
is not supplied to the panel. Trouble relay automatically returns to its previous position with the elimination of the
fault status.
AUX Output (External Supply Output):
The panel has 24VDC 500mA external supply output with automatic
fuse protection. In cases of blackouts, the external supply output is supplied until the battery reaches the cutoff
voltage.
5.7
Zone Lines
TFP-40x Teknim conventional panels may be viewed under 2 options as 4- or 8-zone devices. Detection circuits
provide power (24 VDC) to the detectors and buttons and at the same time ensures that signals like fire alarm,
short circuit, and broken line are transmitted to the panel Maximum 32 detectors or alarm buttons can be
connected to a zone line. Cable coded 1x2x0,8+0,8JY(st)Y should be used for connection distances of 0 - 500
meters and cable coded 1x2x1,5+1,5J-Y(st)Y for connection distances of 500 - 1500 meters.
The form of connection of the zone line with the detector and alarm button is shown in "Appendix-Electrical /
Figure 7 Zone Connection". Unused zones should be disabled over the panel or terminated with the termination
resistance. If no connections are made to the zone, the panel gives the error "Zone Open Circuit".
Zone cables should be kept away from high-voltage cables that may cause interference at the site and from
strong magnetic fields. Earthing of the signal cables must absolutely be made from the earthing bar inside the
panel as shown "Figure 8 Zone Grounding Connection".
