Johnson Controls IFC-640 Placement of Equipment Chassis and Cabinet, Configuration Guidelines

Placement of Equipment

in Chassis and Cabinet

The following guidelines outline the IFC-640’s flexible system design.

Rows: The first row of equipment in the cabinet mounts in chassis CHS-M2. Mount the second, third, or fourth rows of equipment in chassis CHS-4MB(see IFC-640 Installation Man- ual regarding panel output modules) or CHS-4L(for voice com- ponents, see Voice Alarm System Manual).

Wiring: When designing the cabinet layout, consider separa- tion of power-limited and non-power-limited wiring as discussed in the IFC-640 Installation Manual.

Positions: A chassis offers four basic side-by-side positions for components; the number of modules that can be mounted in each position depends on the chassis model and the size of the individual module. There are a variety of standoffs and hardware items available for different combinations and configurations of components.

It is critical that all mounting holes of the IFC-640 are secured with a screw or standoff to ensure continuity of Earth Ground.

Layers: The CHS-M2 accepts four layers of equipment, includ- ing the control panel. The JCPU-640fills three positions (left to right) in the first-installed layer (the back of the chassis); its inte- gral power supply occupies (the left) two positions in the next two layers; the optional display occupies (the left) two positions at the front, flush with the door. Panel output modules can be mounted in several layers with standoffs or an L-bracket as required. Some equipment, such as the JNCA, may be door- mounted directly in front of the control panel. The JNCA mounts onto the DP-DISP or ADP-4B. The JNCA can be used as a pri- mary display for the IFC-640 by directly connecting their network ports (required in Canadian stand-alone applications).

Expansion: Installing an LEM-320Loop Expander Module adds a second SLC loop to the control panel. The LEM-320 is mounted onto the JCPU-640, occupying the middle-right, sec- ond (back) slot on the chassis. If networking two or more control panels, each unit requires a NCM-W(wire) or NCM-F(fiber) Network Control Module. The NCM-W/-F can be installed in any panel output module position (see manual); the default position is at the back of the chassis next to the control panel. Option boards can be mounted in front of the LEM-320 or NCM mod- ules; for ease of access, complete installation of those devices before mounting another layer.

KDM-2 Controls and Indicators

Program Keypad: QWERTY type (keyboard layout).
8 LED indicators: Power; Fire Alarm; Pre-Alarm;	Security;
Supervisory; System Trouble; Signals Silenced; Points Dis-
abled.
Membrane Switch Controls: Acknowledge/Scroll	Display;
Signal Silence; Drill; System Reset; Lamp Test.

LCD Display: 80 characters (2 x 40) with long-life LED back- light.

Configuration Guidelines

Stand-alone and network systems require a main display. On single-CPU systems (one JCPU-640/-640E), display options are the KDM-2 or the JNCA. On network systems (two or more JCPU-640/-640Es), at least one JNCA or IFW annunciation device is required. Other options listed as follows:

KDM-2:80-character backlit LCD display with QWERTY pro- gramming and control keypad. Order two BMP-1 blank modules and DP-DISP mounting plate separately. Requires top row of a cabinet. Required for each stand-alone80-character display system. The KDM-2 may mount in network nodes to display “local” node information as long as at least one JNCA or IFW network display is on the system to display network information.

JNCA: Network Control Annunciator, 640 characters. On single CPU-640/-640E systems, the JNCA is the Primary Display for the panel and connects directly to the CPU-640/-640E. On net- work systems (two or more CPU-640/-640Es), one network dis- play (either JNCA or IFW) is required for every system. On network systems, the JNCA connects (and requires) an NCM network communications module. Mounts in a row of FACP node or in two annunciator positions. Mounting options include the DP-DISP, ADP-4B, or in an annunciator box, such as the JABS-2D. In CAB-4 top-row applications, a DP-DISP and two BMP-1 blank modules are required for mounting. See JNCA technical bulletin.

JCPU-640:Central processing unit with integral 3.0 amp (6.0 A in alarm) power supply for an IFC-640 system. Includes CPU; one Signaling Line Circuit expandable to two; installation, pro- gramming and operating manuals. Order one per system or as necessary (up to 103 network nodes) on a network system.

JCPU-640E:Same as JCPU-640 but requires 220 VAC, 1.5 amp, (3.0 A in alarm).
