Installation Instructions
Model RC-30U
Confirmation Module (Alarm Verification)
Description
The Confirmation Module, Model RC-30U is designed to
assure against unwanted system alarm operation which
might result, as an example, from the presence of occa-
sional, momentary but harmless products of combustion.
The RC-30U will interrupt the transmission of an alarm
signal to the system control panel for a factory set period
of 20 seconds, however, it is adjustable from 1 to 60 sec-
onds. Immediately following the interruption period, a
confirmation period is in effect during which time a subse-
quent alarm signal, if present, will be sent immediately to
the control panel. This confirmation period as factory set
is approximately 1 minute, however, it is dependent upon
the interrupt setting.
During the confirmation period should an alarm signal be
present, it will put the system into alarm condition.
The Confirmation Module is placement sensitive as follows:
• Modules connected between the Confirmation
Module receptacle P2 and the control panel are not
affected by its operation.
• Modules connected subsequent to receptacle P1 of
the Confirmation Module may be affected. This is
determined by which plug (system or zone) is used.
The system plug (orange wire) is for basic applications
where a single alarm interrupt/confirmation cycle is suffi-
cient. See Typical Connection #1. In this application, a
special Plug/Harness Assembly is used between recep-
tacles P4 and P5 and any alarm signal from a module
connected to receptacle P1 will be interrupted for a se-
lected period of time from 1 to 30 seconds (20 seconds is
the standard setting). During this period power to the
modules on receptacle P1 is removed, a yellow LED is il-
luminated, and a system trouble signal is initiated. In addi-
tion, a high-going signal (20mA) is present on a terminal
for use as a pre-signal or for connection to a recording
device. Immediately following the interruption period, the
circuit power is restored, the yellow LED is extinguished,
and the system trouble signal is canceled. This also starts
the confirmation period - a period during which time if any

alarm signal is present, it will be passed through uninter-
rupted to the control panel, and the system will go into
alarm condition. This confirmation period is variable to the
extent that it is a multiple of the duration of the interruption
cycle (one minute is standard). If no alarm signal is
present during the confirmation period, the RC-30U resets
automatically and the system is normal.
The zone plug (white wire) is used for applications requir-
ing various alarm interruption/confirmation cycles - two or
more RC-30Us will be needed. See Typical Connection
#2. In this application only alarm signals from modules
connected to receptacles P1 will not be interrupted/con-
firmed. The interruption and confirmation cycle described
above apply in a zone mode. A yellow trouble LED is pro-
vided on the RC-30U to annunciate a specific trouble
within the RC-30U.
The Model RC-30U which occupies two standard module
positions, is placement supervised, providing a system
trouble signal upon removal from the system. In addition,
removal of the system/zone plug and/or the special Plug/
Harness. Assembly provides a system trouble signal.

Installation
1. Mount the module to the horizontal mounting
brackets in the control enclosure.
2. Install the Model JA-5 (5 in long) bus connector cable
assembly between receptacle P2 of the module and
receptacle P1 of the module or control panel
immediately preceding it in the bus.
