1.
Before connecting any external devices, temporarily power
up the unit and measure the DC output voltage at the device
connection point to avoid damage to devices. If voltage drop
is large, adjust the voltage using the output voltage trimpot
(see Fig. 1). Then disconnect power before connecting
external devices.
2.
See ST-2406 3EAQ LED status indicators in Table 3.
3.
The ST-2406-3EAQ comes with a 5A fuse. Use only the
correct fuses to prevent short-circuits and damage to the
power supplies/chargers or the alarm access control panel.
4.
The automatic low-battery cutoff will cut power when battery
voltage drops below 20% of the set output voltage.
Warning:
1.
Installation and servicing must be performed by qualified service personnel.
2.
The power supply must be installed in accordance with all national and local electrical codes.
3.
Do not use a higher AC input than recommended (rated max. 28VAC).
4.
DISCONNECT THE POWER SUPPLY BEFORE CHANGING THE DIP SWITCH SETTINGS OR
PERFORMING ANY TYPE OF SERVICE. There are no user serviceable parts inside.
5.
Do not touch any exposed metal parts, electrical, or electronic components as these parts may become
very hot under load.
6.
Keep power-limited wiring separate from non power-limited wiring (115VAC input, battery wires). Provide at
least
1
/
4
” (7mm) spacing.
7.
Connect the power supply/charger only to a rechargeable backup battery. Use of a non-rechargeable
backup battery could result in damage to the power supply/charger or the alarm access control panel.
1.
Mount the power supply/charger enclosure in the desired location
to be easily accessible for future servicing.
2.
Set the desired DC output voltage (6, 12, or 24VDC) of the power
supply using the DIP switch settings as shown in Table 1.
IMPORTANT:
Disconnect power before changing these DIP switch
settings (Note the default voltage output setting is 12VDC).
3.
Connect a Class-II transformer with appropriate specifications (See
Table 2 right).
4.
Connect a sealed lead-acid or gel-type backup battery if desired.
5.
Connect the wires to their respective terminals (see "Overview,"
pg. 2 and “Notes” below). Use the supplied grommets to protect the
wires entering the enclosure and secure the AC power wire with the
wire relief clamp and flange nut.
