Seco-Larm ST-BD01Q User Manual

NOTE: Products with model numbers that end with “Q” or have a round green “Q” sticker are RoHS compliant.

 Selectable input 12/24VDC
 Adjustable voltage cut-off and restore point
 Master ON/OFF switch

The ENFORCER ST-BD01Q Low-Voltage Battery Cut-Off prevents the deep discharge
of the backup batteries. The ST-BD01Q ties directly into most 12 or 24 VDC power
supplies or alarm panels for easy plug-and-play installation. A Master ON/OFF switch
easily connects or disconnects the battery and AC power supply from the control panel.

 Green LED AC power indicator
 Dual-color DC LED indicator
 Includes double-sided tape

*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.
