*Must connect for proper operation.
IMPORTANT: The polarity on all wiring connections MUST be
connected properly; incorrect polarity connection will damage the
unit. When using 24VDC the voltage selector switch MUST be set
at 24VDC, incorrectly setting the unit may cause damage.
Specifications:
For operating voltages please see Table 1 on Page 3.
Installation:
1.
Disconnect the AC power and back-up battery from the control panel or power supply.
2.
Turn the master switch of the ST-BD01Q OFF (factory default is OFF).
3.
Select the correct voltage setting (12 or 24 VDC) via the 12/24 VDC selector switch (factory
default is 12VDC).
4.
If necessary, connect the low voltage AC to the AC input terminal block.
5.
Connect the AC output gray wires from the ST-BD01Q to the AC input of the control panel or
power supply.
6.
Connect the male spade terminals of the ST-BD01Q to the DC output terminals of the control
panel or power supply.
Must connect for proper operation.
7.
Connect the female spade lugs of the battery wires to the back-up battery.
Observe correct polarity.
8.
Use the included double sided tape and secure the ST-BD01Q module on the desired location.
9.
Double check all connections before turning the master switch ON.

or Control Panel
1.
The ST-BD01Q turns off both AC and DC power to the control panel or power supply.
2.
The green LED indicates AC power is present.
3.
The dual-colored LED indicates DC power is present and if it is 12 or 24VDC (see Table 2).
Master ON/OFF Switch:
1.
The ST-BD01Q’s voltage cut-off point is preset at approximately 9.6VDC when set at 12VDC
setting and about 19.6VDC when set at 24VDC setting.
2.
To adjust the voltage cut-off point, carefully turn the adjustable voltage cut-off knob clockwise
to increase and counter-clockwise to decrease. See the Table 1 below for the adjustable
voltage cut-off range.
