Forney UniFlame II User Manual
UniFlame® II Unitized Flame Detector
Forney’s UniFlame® II series ame
detectors utilize micro-processor based
controllers in conjunction with solid
state infrared (IR) and ultraviolet
(UV) sensors and dual cell technology
for optimal ame detection and
discrimination.
Features & Bene ts
MAXIMUM FLEXIBILITY
• AutoTune - Fast auto set-up by “learning”
the ame and background conditions
• UniFlame® II senses both UV and IR with
independent exible discrete outputs

Product Overview
e UniFlame® II’s integrated ampli er eliminates the remote ame
ampli er and incorporates two independent ame relays with electronic
self-checking, adjustable ON/OFF thresholds and two 4-20 mA analog
outputs from the detector. Each ame relay can be set for either sensor
(one for UV, one for IR or both for UV or both for IR). Independent
settings for each relay allow “locked on” detection for any type of ame.
Set-up can be done locally using the attached keypad & VFD display,
via a wireless handheld programmer or with Forney Explorer Software
(FEX). e optional wireless handheld programmer creates an intrinsically
safe wireless set-up when using the infrared transmitter within 5 feet of
the detector, eliminating the need to open the detector in order to make
program changes. FEX Software allows users to monitor, display and
program all detector parameters remotely, i.e. from the control room. e
detector has three factory default les provided in various sensitivity levels
that can be used to initiate and test the detector. e auto tune feature
allows the user to learn the “ ame on” and “background” conditions to
automatically set the detector up.
Connecting to the UniFlame® II is done by multi-pin connectors or
terminal blocks. e standard UniFlame® II has one 8-pin and one 12-
pin electrical cable quick disconnect while the CEX versions use internal
terminal blocks for cable connection.
