relative humidity, non-condensing. (If
ordered for UUKL Smoke Control
Systems, 32 to 120.2 °F [0 to 49 °C]; 10 to
85% relative humidity, non-condensing.)
Status Indication
Visual (LED) status of
CMnet and Unet communication,
running, errors, and power.
Memory
1MB Flash memory and 1MB non-
volatile battery-backed RAM.
Real Time Clock

retention during power outages.
Listed by
UL 916 (PAZX), cUL C22.2 No.
205-M1983 (PAZX7), FCC Part 15 -
Subpart B - Class A.
Mounting
Screw the UNI/59 into an enclosed panel
using the mounting holes provided on the
cover plate. Be sure to leave about 2 inches (5
centimeters) on each side for wiring.
Power Wiring
CAUTION
The UNI/59 module is a Class 2
device (less than 30VAC, 100VA maximum).
Take appropriate isolation measures when
mounting the UNI/59 module in a control
panel where non-Class 2 devices (120VAC or
greater) or wiring are present.
You can power several modules from the
same transformer if you maintain the same
polarity.
The UNI/59 has an operating range of
21.6VAC to 26.4VAC. If voltage measured at
the module’s power input terminals is outside
this range, the module may not work
properly.
1. Turn the module’s power off. This
prevents the module from being powered
