Thermal Probe - Bentel Security KYO 320 Installation Manual

n Thermal Probe
This Control panel has an on-board connector 31 for a
KST thermal probe (accessory item). The probe will op-
timize the backup battery charge process, by regulating
the charge voltage in accordance with the temperature
of the backup battery.
Work carefully through the following instructions (refer
to the figure on page 10):
1. Connect the probe 9 to the connector 62 (PTC) on
the Switching Power supply.
2. Attach the probe to the backup battery, in such a
way as to obtain optimum heat transfer.
3. Connect the connector of backup battery 53 on
the PCB.
4. Measure the Probe temperature.
5. Using the graph in Figure 24 and/or Table 3, find
the value (in accordance with the battery tempera-
ture) that the Switching Power supply output volt-
age will be based on.
6. Using the trimmer 54, adjust the voltage on the ter-
minal board 55 to the required value.
