METHOD OF INSTALLATION
GENERAL
Conduct a site survey
Coordinate the location of the storage of materials on site
Review the approved shop drawings before work commencement on site
Coordinate the Fire Protection Works with the various contractors
Install a mockup area to ensure all coordination works are done as agreed, and to get the work quality and samples inspected and approved by [Company Name] and the Consultant
All Electrical Tools, Ladders & scaffolding are to be Certified by Safety Officer
INSTALLATION
Fire Alarm control panel:
Choose a location for the fire alarm system that is clean, dry, and vibration–free with moderate temperature. The area should be readily accessible with sufficient room to easily install and maintain it. There should be sufficient space for the cabinet door to open location should show in the shop drawing and be approved by the consultant and relevant local authorities requirements.
Carefully unpack the system and inspect for shipping damage. Count the number of conductors needed for all devices and find appropriate knockouts
Installers should be familiar with the standards and codes of the system
All wiring complies with the national and local codes for fire alarm systems
Do not draw wiring into the bottom 9 inches of the cabinet except when using a separate battery cabinet; this space is for internal battery installation
Mount the cabinet back box to the wall
Attach CPU to chassis
Attach panel circuit modules and option boards (e.g. SLC loop, modules, network communications modules, and other devices of the same size) to the chassis.
Attach chassis to the back box as appropriate for system design
Wire notification appliance circuits and initiating device circuits relays
Attach & wire other system components
Wire the Signaling line Circuits
Calculate the proper battery ratings
Install the main power supply & batteries in separate enclosures Run the cable to main & optional power supplies, Dc power Outputs, relays, etc.
Check that all mounting holes are secured to insure a proper earth Ground connection.
Connect wire shielding to Earth Ground.
Remove the insulator from the lithium battery on the CPU.
Apply AC power to the control panel by placing the external circuit breaker in the ON position. DO NOT connect batteries until AC power is checked
Check AC power.
Connect the batteries using interconnect cable as described in the power supply manual.
Install the dress panels, doors, and covers.
Program the control panel.
Field test the system
Provide a schematic diagram placed in every panel
Fire Alarm Repeater panel:
Mount and ground the cabinet or back box
Pull wiring into the back box
Configure RDP bus ELR DIP switch
Connect earth ground mounting to a mounting screw on the back box or cabinet
Mount the optional Annunciator key switch
Make all electrical connections (RDP bus & shielding, power circuit)
Mount the LCD-160 in the back box
Attach doors to the back box
Power up the system according to instructions in the control panel manual
Configure the LCD-160
Circuit diagram to be placed inside the control panel
DVC
Carefully unpack the system and inspect for shipping damage .count the number of conductors needed for all devices and find appropriate knockouts
Installers should be familiar with the standards and codes of the system
All wiring complies with the national and local codes for fire alarm systems
Mount CA-1 or complete CA-2 chassis assembly into the back box either at this point or after components have been installed
Mount any option boards to the DVC(DVC-AO, DVC-KD)
Load the CA-2 or CA-2 chassis
Mount an NCM-WF onto the DVC half chassis
Mount an LCM-320 or stacked LCM-320/LEM-320 onto the NFS-3030 chassis
Mount the MIC-1 and optional TELH-1 handset into the chassis well
Detectors
All wirings must be installed in compliance with the National Electrical Code, applicable codes, and the Authority having jurisdiction. Proper wire and wire gauge should be used.
Wire the sensor base as per the wiring diagram
Set the desired address on the sensor address switch
Install the sensor into the sensor base. Push the sensor in the base while turning it clockwise to secure it in place
After all the sensors have been installed, apply power to the control unit and activate the communication line.
Test the sensor
Location of each detector to be inline and in good finishing
Pull Station
All wirings must be installed in compliance with the National Electrical Code, applicable codes, and the Authority having jurisdiction. Proper wire and wire gauge should be used.
Wire the Pull station base as per the wiring diagram
The NBG -12LX Addressable pull station can be surface mounted to an SB-10 or SB-I/O surface back box
The pull station includes one Single Pole, Single Throw (SPST) Normally open (N/O) switch which closes upon activation
Reset the pull station
Insert the key into the lock and rotate ¼ turn counter-clockwise
Open the door until the handle returns to normal
Close and lock the door
Modules
All wirings must conform to applicable local codes, ordinances, and regulations.
Module mounts directly to 4” square electrical boxes. The box must have a minimum depth of 2 1/8” surface-mounted electrical boxes (SMB500)
Install module wiring following the job drawings and appropriate wiring diagrams
Set the address on the module as per the job drawings
Secure the module to the electrical box
VISUAL CHECK
Check the layout of the Detector, Call point, power supply, alarm sounders & other accessories installed as per approved / as-built drawings
Check all the monitor modules and control modules' locations as per the final approved shop drawings. The monitor modules and the control modules represent the Fire Alarm interface which should be interfaced with the other extra systems.
Check for connection to Lifts for interfacing by checking the control module connections. To also check its address using the Fire Alarm Control Panel and then check the function in case the fire alarm signal (the control modules should give output signal to the BMS and the lifts control panel)
Check connections at Detector bases, termination to panels, and end-of-line devices
Continuity check with the end-of-line devices
In loop and network wiring conductor to conductor resistance at the end of the return line
Check AC power 220VAC in the power source before connecting the FACP
CONTROL PANEL SETTING
All circuit boards are correctly fitted
All internal wiring connectors are properly mated
Detectors, call points, modules, and sounder circuits are configured as relays if so is required
All the end-of-line resistors should be properly connected
Connecting power, All front panel LED indicators should be extinguished except the POWER LED
View the LCD. It should display and read Status NORMAL (date and time) unless faults are present in the system. If the panel has already been configured, then faults indicating the loss of all devices will be shown
If faults are shown other than the loss of loops on a configured panel, these must be cleared before you proceed further with the procedure
Externally isolate the AC mains supply at the third party – supplied isolation unit
PROGRAMMING AND TESTING
Once the system has been physically installed, programming may begin. The user may program at any time except there is an unacknowledged alarm present
To ensure security, passwords should be entered at this point replacing the factory default settings.
For initial programming of the panel, or major changes and additions, the following basic procedure is recommended to prevent errors resulting in reprogramming and wasted time
Use worksheets to record the exact information for every detector, module, annunciator point, and software zone in the system. Pay close attention to the software type IDs. For voice systems, pay close attention to AMG annunciator point commands. The panel may also be created using VeriFireTM tools and downloaded to the panel after assembly and power up
Assemble and apply power to the control panel as described in the installation manual
Enter/Change master and user password
Enter panel and network parameters
Program all devices and thoroughly test the entire system. The Walk test feature can be used to test the devices and their programming
Make a hard copy record on the printer
Save the program by uploading it using VeriFireTM Tools
CENTRAL MONITORING (If applicable)
Configuring the central monitoring system based on panels configuration
Enter the panel, detectors, and call point location on the graphics circuit, and the call point and detector address
Check the functional test from the central monitoring unit
