3.4.3 DC Uninterruptible Power Supply (DC-UPS) Module
The DC-UPS Module can be used with the separate and optional TPPR Battery Enclosure to provide continuous and
uninterrupted power to the TPPR in the event of an external power failure.
The DC-UPS is adjustable for buffer time and buffer voltage, and carries red, yellow and green status LEDs and descriptions
that show your backup battery status (see tables below).
Note: The DC-UPS Module Buffer Voltage should be set at 26 VDC to ensure optimum battery charging, and the Buffer-time
Limiter should usually be set to ∞ (see circled area on the figure below).
The DC-UPS terminals are as follows:

The DC-UPS also has Normally Open (NO) relay terminals that can be used for external repeaters such as a lamp stack or
alarm buzzer, as shown in the table below:
