3.4 Auxiliary 24VDC Input
If an Auxiliary 24VDC Input is to be connected to the unit, the voltage may need to be adjusted to insure
proper operation. If the 24VDC input is being used to operate the unit, the source must be able to provide at
least 7Amps to insure proper unit operation. The unit utilizes a 10A Circuit Breaker to provide over current
protection.
Measure the voltage across the power supply output (V+ and V-). This voltage should read 24 ±2.4VDC. If
the 24VDC Input is to be used as a Backup or Auxiliary 24VDC Input, adjustments may be required to insure
that it is below the internal power supply voltage. If the voltage measured across the Power Supply is lower
than the Auxiliary 24VDC Input, the internal power supply will not be utilized to supply power to the unit.
The Auxiliary 24VDC Input to the unit should be adjusted to at least 0.1~0.15VDC below the unit’s 24V
Power Supply for correct operation. This will insure that the unit does not operate on the Auxiliary 24VDC
Input unless the AC input power is lost.
3.5 880 Remote Display Installation (Optional)
The Detcon Model 880 Remote Display enclosure is rated NEMA 4X, which is rain tight and suitable for
outdoor locations in electrically non-hazardous environments. The enclosure is equipped with four (4) wall-
mounting brackets for easy wall mount installations. Care should be given to prevent sharp objects from
colliding with the touch screen. The screen can be cleaned with a mild detergent and a lint free cloth. Never
use an abrasive cleaner on the display.
1. Securely mount the 880 Enclosure in accordance with Figure 17.
