GENERAL INFORMATION

The Honeywell U2-101xS series model is a viewing head 
and signal processor in a single enclosure intended for 
use with a burner control system in Industrial Flame 
Monitoring applications. There are several options 
available (see Table 1 on page 2). Each model includes 
one, two, or all three sensors, and can be ordered with 
quick disconnect (non-PF Models DIV2,ZN2) or pigtail 
external connection method (PF Models DIV1,ZN1).

Each sensor operates independently from another, 
allowing adjustment of each sensor.

IMPORTANT

Flame monitoring systems are safety systems.
Please read this manual carefully and completely 
before installation and before attempting adjust-
ments.
Only qualified personnel familiar with Flame 
Safety System should carry out installation and 
configuration. 
U2 is certified to be used in prescribed manner. 
Any modification or inappropriate installation or 
operation may result in unsafe operation and will 
void implied or expressed warranty.

Sensors

The UV tube detector has a peak response at 210 nm.

The IR solid state sensor has a peak response at 1400 nm.

The UV solid state sensor has a peak response at 310 nm. 

Cabling Options (Sold Separately)
