SIEMENS RC-30U Confirmation Module Instruction Manual

SIEMENS RC-30U Confirmation Module

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 occasional, 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 seconds. Immediately following the interruption period, a confirmation period is in effect during which time a subsequent 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 sufficient. See Typical Connection #1. In this application, a special Plug/Harness Assembly is used between receptacles P4 and P5 and any alarm signal from a module connected to receptacle P1 will be interrupted for a selected 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 illuminated, and a system trouble signal is initiated. In addition, 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 uninterrupted 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 requiring 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/confirmed. The interruption and confirmation cycle described above apply in a zone mode. A yellow trouble LED is provided on the RC-30U to annunciate 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.

Electrical Information

• Current Requirements:
  • Normal – 5mA
  • Duration of interruption period – 100mA @ 24VDC max
  • Duration of confirmation period – 62mA @ 24VDC max
  • Alarm – 40mA max

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.
   • 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, Installation and Wiring.

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.
