SECO-LARM U.S.A., Inc. 5
B. Wiring
1. Unplug terminal blocks from their sockets for easy installation.
2. Connect equipment power input cables to the screw terminals side by side in N/P pairs.
3. Screw the terminals closed. Once done, reinsert the terminal block back into its slot.
4. Select channel voltage for each terminal block with the switches on the back of the unit.
5. For each group of channels, select either 24VAC or 28VAC. Switch unused channels to OFF.
Tech Tip: Group cameras with similar power-cable lengths on the same terminal block and set
the 24/28 VAC switch to compensate for voltage drops. Test voltage after changing settings.
Caution: Do not set 28VAC unless voltage drops under 21.5VAC to avoid camera
damage, etc.
6. Connect the unit’s power cord to a 120V outlet and switch on the unit.
7. Front-panel LEDs for channels set to 24 or 28 VAC should glow blue to show output is on.
8. Test the output at the camera end of each power cable to be sure voltage is correct.
Caution: Always test output voltage before connecting cameras or other equipment.
9. For cable management, see page 6. For example applications, see page 7.
C. Replacing the Main Fuse
Caution: Replace only with same
fuse type and rating.
1. Find the main fuse at the back of
the unit, between the power cord
socket and the ON/OFF switch, as
show in Figure 5 on the right.

USE ONLY WITH A 250V FUSE
2. To check or replace the fuse, first power the unit and remove the power cord.
3. Use a flat-head screwdriver to gently lever the fuse holder out at the place shown in Figure 5.
Be careful not to damage the soft plastic fuse holder with the screwdriver.
Tech Tip: There is a spare fuse in the top of the fuse holder—use the old fuse to push it out.
D. Replacing the Channel Fuses (Glass Fuse Models Only)
Note: PTC fuses automatically resets when current overload is fixed or removed.
1. Check if the front panel lock tab has been installed.
2. If so, remove it following the instructions in the section Using the Front Panel Lock Tab below.
3. Press on the front panel at the place marked “Push” on the upper middle of the panel.
4. The panel will click open and swing downward.
5. Each unit is equipped with spare fuses: 3 for 16-channel models; 6 for 32-channel models.
6. The spares are found in white fuse holders mounted conveniently on the circuit board.
Caution: Use caution when replacing fuses in order to avoid shocks or shorts.
E. Using the Front Panel Lock Tab (Glass Fuse Models Only)
1. Use the front panel lock tab when greater safety or security is needed.
2. The lock tab prevents the front panel from being opened accidentally or by unauthorized persons.
