ANNUNCIATOR PANEL MOUNTING
For ALL models installation must always comply
with applicable codes, standards, laws and regula-
tions. Adhere strictly to local, state and national
electrical and building codes. Comply with regula-
tions the Occupational
Administration (OSHA) have established. Also, the
generator and related components must be installed
completely in conformance with the manufacturer's
instructions and recommendations. Following prop-
er installation, do nothing that might alter a safe
installation and render the unit in non-compliance
with such codes, standards, laws and regulations.
The Remote Annunciator panels (Models 000985-0,
004281-0, 004392-0, 000985-1, 004281-1) are intend-
ed for flush mounting. Panel mounting dimensions are
shown in the illustration below.
installed behind a cutout in an existing sheet metal
panel by using the four mounting holes in its front
panel. For wall mounting, use a square outlet box
behind the annunciator panel.
Flush Mounting Dimensions
The Remote Annunciator panels (Models 000984-0,
004280-0, 004391-0, 000984-1, 004280-1) are mount-
ed using any combination of the mounting holes in the
back panel of the box itself.

20 Light Remote Annunciator

SYSTEM SPECIFICATION

The 20 Light Remote Annunciator Panel (RAP) directly
interacts with the the D/E panel generator and provides
remote monitoring and annunciation of 17 generator
parameters, 2 system-level warnings—System Ready
and Communications OK and 1 spare channel.
Health It is similar to the existing Model 09556-0 Remote
Annunciator unit which interfaces with the 'C' Panel
display, the main difference being that it interfaces to
the D/E Panels via a 2 wire RS485 serial data link rather
than a direct multiway cable.
Power to the RAP is supplied from the generator battery
(+12V to +24V) via a 2 wire link.

PASSIVE MODE

The 20 light remote annunciator is an active device
which periodically makes a request to the generator
control panel for information. However, the 20 light
annunciator can be set to passive mode. This mode
allows the user to connect a second 20 light remote
annunciator to the generator control panel.
SETTING TO PASSIVE MODE
This passive mode feature is available on Models
000984-1, 000985-1, 004280-1, 004281-1. To set the
20 light annunciator to passive mode, simply connect
an 18 to 22 gauge wire between header positions J3-1
and J3-2.
1. It is not recommended to connect more than a
total of two 20 light remote annunciator panels.
(one set to active mode, one set to passive mode)
2. Up to four remote relay panels can be used with
the two 20 light remote annunciators.
3. If only one 20 light remote annunciator is con-
nected to a generator control panel, it must be left
in active mode. (without the wire link between
J3-1 and J3-2)

HARDWARE FUNCTIONAL DESCRIPTION

The RAP queries the D/E panel once every three seconds
and receives the generator status parameters. It will
update the light panel and audible annunciator as
detailed below.
