The Informer is a hand-held diagnostic tool designed for
use with single-phase models equipped with infrared LED
transmitters (111-Insider-P; 231-Insider-P; 232-Insider; 111P;
233P; 233P-1.5; 234-P and 235P).
The Informer uses an infrared receiver to access information
sent from the relay which can be helpful for troubleshooting
the system.
Each Littelfuse single-phase relay model, equipped with an
infrared LED, transmits valuable information from the device.
To retrieve this information, the Informer’s receiver must be
directed toward the relay’s LED transmitter and be within 8 feet
of the unit. The green COMM STATUS light indicates when the
Informer is receiving data from the relay. If communication is
lost, the Informer will display the last values it received. The
Informer will automatically shut off after 2 minutes of non-use.
An infrared adapter (IR Kit-12) is included with all new and
updated Informers. This adapter allows communication with
the relay without opening the panel door.
