Electronic Identification Sign

The Sirchie 893PA is an electronic digital identification sign built around an 8-bit microprocessor with 2048-byte EPROM and 32-byte RAM. It uses a dual bank of liquid crystal displays for clear visuals and a swing-down front panel that reveals an entry keyboard. All-CMOS circuitry keeps power draw low during operation.

Replaces manual boards

This unit replaces hand-written or static identification boards where information changes often. The jump is worth it when you need rapid, keyless data entry without knobs or insertable numbers. Battery operation removes the need for wired power at the mounting point, simplifying installation in corridors or entryways.

LCD and battery limits

The liquid crystal displays depend on ambient light and may be hard to read in dark areas without external illumination. Internal AA alkaline cells supply a maximum 15 mA during data entry and 2.5 mA in standby, so battery life varies with how often the keyboard is used. No AC adapter or external power connector is provided.

Questions about this item

How many AA batteries does the 893PA sign require and how are they accessed?

The unit is powered by four internal AA alkaline batteries reached through the battery cover on the housing.

What is the correct sequence for entering data on the swing-down keyboard of the 893PA?

Open the swing-down front panel, press the desired key numbers directly on the keyboard, then close the panel to secure the entry.

How long will the four AA alkaline batteries last in standby on the 893PA sign?

At a maximum standby drain of 2.5 mA, a typical set of AA alkaline cells provides several months of operation before replacement is needed.
