SET DETECTOR SENSITIVITY ALARM _._ (0.5 -3.0 / FT)
6. This prompt asks the user for the Alarm level for the Detector(s) to be set. Key in the desired Alarm level and press the return key. After pressing return the display will read:
LEVELS SET ON XX DETECTORS
7. This message verifies that the desired sensitivity adjustments were done on XX amount of detectors.
The sensitivity of all specified detectors (depending on which type was previously selected) will be set in the previous procedure.
7-15 ADDRESSABLE CONTACT INPUT
DEVICE INSTALLATION
The Addressable Contact Input Devices are designed to be installed in a North American 2-1/2 in. (64 mm) deep one-gang box, or a standard 4 in. square box 1-1/2 (38 mm) deep with a one-gang blank cover. The AI terminal
block will accept #14, #16, and #18 AWG wire (1.5, 1.0, and 0.75 mm2 respectively) with size #18 being a minimum requirement. Refer to the wiring the diagram in Appendix I for specific connection information. Also refer to Chapter 2, Paragraphs 2-8.6 and 2-8.7 for set-ting addresses and other parameters. The installation must comply with national and local electrical codes.
7-16 ADDRESSABLE RELAY OUTPUT
DEVICE INSTALLATION
The Addressable Contact Output Devices are designed to be installed in a North American 2-1/2 in. (64 mm) deep one-gang box, or a standard 4 in. square box 1-1/
2 (38 mm) deep with a one-gang blank cover. The AI terminal block will accept #14, #16, and #18 AWG wire (1.5, 1.0, and 0.75 mm2 respectively) with size #18 be-ing a minimum requirement. Refer to drawbe-ing number 06-234563-001 located in Appendix I, for specific con-nection information on both devices. Also, refer to Chap-ter 2, Paragraphs 2-8.6 and 2-8.7 for setting addresses and other parameters. The installation must comply with national and local electrical codes.
Note: All Non Power Limited wiring must be routed away from Power Limited wiring by a minimum of 1/4", per NFPA and UL requirements. For Power Limited Circuits use Type FPL, FPLP, or FPLR cable per NEC Article 760.
7-17 INSTALLATION CHECKOUT
Before powering-up the FenwalNET 2000 for the first time, ensure that the following has been completed:
1. Central Control Module (CCM), RX/TX Module and System Power Supply are secured to the back of the enclosure.
2. CCM is connected to the RX/TX Module, Display Assembly, System Power Supply (I/O bus and 24 Vdc), and Remote RS-232 peripheral(s) if any.
3. CCMs configuration jumpers configured correctly to insure proper operation of the programmable (sig-nal / release) output (MP1).
4. Optional Motherboard if installed, is connected to the CCM (I/O bus) and System Power Supply (24 Vdc).
5. RX/TX Module is connected to the CCM (RJ-12) and system power supply (24 Vdc).
6. Output Modules if used, are installed in the Motherboard, addressed correctly, configured for appropriate mode of operation and their external wiring is connected correctly.
7. Perform the Power-Up procedure in Chapter 4, Para-graph 4-5.
8. Refer to Chapter 2 for system operations and programming.
7-18 CONNECTION OF PERIPHERALS
The following paragraphs will describe how to connect a terminal or personal computer and a printer.
7-18.1 Connecting a Terminal or Personal Computer
A UL Listed EDP terminal or computer can be connected to the systems RS-232 port. A 6-wire RJ-12 type modu-lar phone jack (PC port), located on the CCM, provides easy connection.
The terminal or computer connection cable must have a RJ-12 type modular phone plug that connects to the CCM (use P/N 74-100016-003, for a DB9 connector for laptops, or P/N 74-100016-001 for a DB25 connector for personal computers). The connector at the terminal end must be of the type required by the terminal device.
Route the connection cable to one of the RS-232 modu-lar plug into the jack until it snaps into place. The ter-minal or computer must be located in the same room as the Central Control Panel.
The parameters for the RS-232 printer port are as follows:
9600 Baud
8 Data Bits
1 Stop Bit
No Parity
Note: These parameters are fixed and not adjustable.
The PIN and function for the RS-232 printer port are as follows:
1 = TX
2 = Signal Ground
3 = RTS
4 = CTS
5 = N/C
6 = RX
7-18.2 Connecting a Printer
The RS-232 printer port of the CCM is a supervised connection. The installer must enable the printer port for operation. The enabling or disabling of the printer port would be done by accessing the 1st or 2nd level menu.
A simple connection cable is all that is needed to con-nect the serial printer to the RS-232 port of the CCM.
The following diagram represents the cable.
