Installation Manual
ST-series
Power Supplies/Chargers
Features:
• Automatic recharging of back-up batteries.
• Several models to choose from.
• Programmable DC voltage output.
• Built-in battery short-circuit protection.
• Fused output for a regulated charge.
• Automatic switch-over to the backup battery if main power is lost or cut.
• LEDs indicate power status.
• Includes foam tape and battery leads for easy installation.
• Regulated and filtered output voltage.
What it is:
SECO-LARM’s ST-series of power supplies/chargers ensure that alarm systems and access control systems always have
enough power to do their job. Protected by fused output, input polarity protection diodes, and back-up battery polarity
reverse protection, these power supplies/chargers can be used to maximize the security and efficiency of nearly any alarm
or access control installation.
Fused Output:
The ST-1206-1.5AQ comes with a 3A fuse. The ST-2406-2AQ, ST-2406-3AQ, and ST-2406-5AQ models come with a 5A
fuse. The ST-2406-7AQ and ST-2406-10AQ come with a 10A fuse. Use only the correct fuses to prevent short circuits
and damage to the power supplies/chargers or the alarm access control panel.
WARNING:
Connect these power supplies/chargers only to a rechargeable back-up battery. Use of a non-rechargeable back-up
battery could result in damage to the power supplies/chargers or the alarm access control panel, as well as leakage or
explosion of the battery.
Installation:
1. Mount the PC board in the desired location or enclosure. It must be easily accessible for future servicing.
2. DC Power Output Setting:
a. To program ST-1206-1.5AQ DC voltage output:
1. 6VDC — Cut the wire loop, and connect to a 12VAC/20VA transformer.
INSULATE THE CUT WIRE LEADS so that they do not come in contact with the power supplies/chargers.
2. 12VDC — Leave the wire loop uncut, and connect to a 16VAC/40VA transformer.

b. To program ST-2406 Series DC voltage output:
1. Set the desired DC output voltage ( 6, 12, or 24 VDC ) of the power supply using the DIP switch.
See Table 2.
2. The default voltage output setting is 12 VDC.
