If alarm system actuates, it is necessary to found out and eliminate the cause of its
actuation (see para. 8).

Connection of auxiliary devices to CHD:
The following devices can be connected to the charging device (see Figure 9):
-
temperature sensor of SB DTS-135,
-
alarm unit AU-106,
-
panel control of storage batteries BCP-136.
Temperature sensor DTS-135 is designed to control temperature of the charged battery.
The temperature sensor is recommended to be used as a part of PS/CHD with helium batteries.
Temperature sensor DTS-135 is connected to terminals “TS” (see Figure 9).
Alarm unit AU-106 is designed to inform about transfer of PS to abnormal mode by
light and audio signal and is used in cases of PS installation inside the panel or in the facilities
being distant from the house (see para. 7.1.1). Alarm unit AU-106 is connected to terminal “AU-
106” (see Figure 9).
The control panel of storage batteries BCP-136 is designed for remote control of any PS
configurations (see para. 7.1.2). Connection is carried out with a standard interface RS-422. The
control panel of storage batteries BCP-136 is connected to terminal “Remote/Bat_control”. The
control panel of storage batteries BCP-136 allows setting the PS remotely, displaying current
voltage and charging current of the storage battery, signaling about alarm situation.
Also, it is possible to connect the PS to COM-port of the computer or other control
device for setting or displaying PS state. For full information about connection refer to the
manufacturer.
7.1.1.
External unit of alarm AU-106
When installing the PS inside the panel or ancillary facilities, from which PS alarm
signals can’t be heard, external alarm unit AU-106 is recommended to be used (see Figure 10).
Figure 10. External view AU-106
External alarm AU-106 actuates in case of closing/opening “potential-free contacts” of
PS relay. Supply of AU-106 is carried out from the charged SB or from other independent power
supply sources.
