Johnson Controls UZC-256 Manual

UZC-256
Universal Zone Coder
Software Release 2.0

General

The UZC-256 Universal Zone Coder enables the Johnson
Controls intelligent fire alam control panels (FACPs), network
control annunciators and compatible legacy systems to pro-
vide positive non-interfering successive zone coded outputs.
Up to 256 separate codes may be programmed to operate on
the three coded outputs. Each output is used to code or pulse
up to 3 Amps of Notification Appliance power.

Features

• Coded output from the UZC-256 can be fed to multiple out-
put circuits.
• Up to 256 individually programmed codes.
• Three 3-Amp outputs.
• Programmable rounds of code (1 to 99 rounds).
• Up to four digits per round.
• Up to 15 pulses per digit of code.
• Optional general alarm.
• Programmable code and round(s) delay.
• Programmable pulse and digit pause times.
• Connects and communicates over panel EIA-485 interface.
• Programmable for California code.
• Weight 1.75 lbs.

Release 2.0 Features

• Secondary UZC use: counting alarm operation activates
UZC relays after specified number of alarms.
• Programmable address EIA-485 range (1-32).
• No code/counting selection for non-fire points.

Applications

The UZC-256 provides three outputs that supply unique coded
information to certain output circuits, depending on the alarm
initiation condition. This can be useful when employing coded
outputs in floor-above, floor-below applications, or to provide
various numbers of rounds for bell circuits and strobe or lamp
circuits.
NOTE: Due to the nature of coded outputs, the UZC-256 is not
compatible with notification devices which do not produce a steady
or non-periodic sound. Periodic appliances that produce their own
code (such as some codes available with electronic sounders) will
not be compatible with the UZC-256. Refer to the UZC-256 Instal-
lation Manual for a list of compatible panels.
Construction & Operation
The UZC-256 provides three coded output relays, each rated
for three amps at 30 VDC. These relays are controlled by a
predefined program, and can be set to respond to general
alarm conditions with the fire alarm system.
The UZC-256 and the CPU use the EIA-485 circuit for commu-
nication. When installed, the zone coder has a programmable
address on the EIA-485 interface.
Assignment of points to zone codes within the UZC-256 is
automatic in the FC2000; it is programmable in the IFC-2020/
UZC-256 Universal Zone Coder
1010, IFC-3030, IFC2-3030, JNCA, and JNCA-2 (see pro-
gramming manuals for details).
