Unimode 4-16 Installation
Mechanical Installation
In a Unimode 4-16, the ADT-UZC-256 mounts beneath the third (right most) module. The
ADT-UZC-256 fastens to the back of the box using three hex standoffs (one aluminum and
two nylon provided), which are screwed into the three female PEM nuts as shown. The
ADT-UZC-256 is then attached to two of the four standoffs using captive screws on the board
(see Figure 3 - 2).

Electrical Installation

Connect the main power harness from the Unimode 4-16 power supply to P3 on the
ADT-UZC-256. Connect the power harness provided with the ADT-UZC-256 from P2 on the
ADT-UZC-256 to the CPU-500. See Section Two for all terminal assignments.
Connect the EIA-485 annunciator signal from the two-terminal connector on the lower CPU
board (TB-2) to the EIA-485 IN terminals on the ADT-UZC-256.
For connection of notification appliance power to and from the ADT-UZC-256, refer to the
power configuration illustrations in Section Four.
