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.

Notes:

1. Note the specific color of the zone plug and the system plug.

The system plug (orange) confirms all zones as a function of a

system alarm, whereas the zone plug (white) may confirm some

zones and not others. Refer to the plug arrangement and the

modules controlled in the above examples.

2. P2 is the incoming bus plug and must be connected to the

control panel.

3. Operation - The RC-30U interrupts the transmission of an alarm

signal to the system control panel for a factory-set period of 15

seconds. Immediately following the interruption period, a

confirmation period is in effect, during which time a subsequent

alarm signal, if present, is sent immediately to the control panel.

This confirmation period is factory-set at 1 minute.

4. The RC-30U cannot be used to confirm shorting zones.

5. Terminals 1 and 2 are provided in case a trouble output delay is

desired. If it is, remove jumper terminals 1 and 2, and connect

terminal 1 of RC-30U to terminals 1 and 2 of the TL-30U and

terminal 2 of RC-30U to terminal 3 of the TL-30U. The TL-30U

delay must not exceed 200 seconds.

6. When the RC-30U module is installed, apply the WARNING

label (P/N 575-287974) enclosed to the inside of the control unit

door where it is plainly visible.

7. Minimum wire size: 18 AWG

Maximum wire size: 12 AWG

8. Refer to P/N 315-093680 for power limited connections.

9. All terminals are non-power limited on the RC-30U.

Note: If the preceding module is on another row in

the enclosure, a JA-24 (24 in long) bus connector

cable assembly will be required.

3. Modules are to be bus-connected from right to left.

For two-row enclosures, the modules in the lower row

are to be connected from left to right. Succeeding rows

are to be alternately connected, right to left, left to

right, etc.

4. If a module is the last module in the system, install

either a JS-30 (30 in long) or JS-64 (64 in long) bus

connector assembly from the unused receptacle of

the last module to terminal 41 of the CP-35 control

panel. This completes the module supervision circuit.

5. Wire the circuit(s) as described in the CP-35 Control

Panel Instruction Manual (P/N 315-085063) Installation

and Wiring. Refer to the Wiring illustration.

Note: If a zone is not used, the EOL device should

be connected to the alarm initiating circuit terminals 2

and 3 (Zone 1) or 4 and 5 (Zone 2) of the module.

6. If a supplementary relay module, annunciator, or

other output module is used, then the alarm outputs,

terminals 1 (Zone 1) and 6 (Zone 2), should be

connected to these units.

Wiring Test

Refer to the CP-35 Control Panel Instruction Manual, In-

stallation and Wiring.
