System Architecture and Bus Technology

The 5700 control panel adopts a modular bus architecture, mainly including signal line circuits (SLC) and auxiliary buses (SBUS).

1. Signal Line Circuit (SLC)

The SLC loop is used to connect addressable detectors and modules. The system supports two protocols, and users must choose one in programming, which cannot be mixed:

SK protocol: supports 50 detectors and 50 modules (a total of 100 devices), with device addresses set through a rotary dip switch

SD protocol: Supports 50 detectors and modules (a total of 50 devices), with detector addresses set through panel programming and module addresses set through DIP switches

SLC wiring specifications:

SK equipment: maximum loop resistance of 40 Ω, maximum distance depends on wire specifications (maximum 1200 feet for 22AWG, maximum 7900 feet for 14AWG)

SD equipment: maximum loop resistance 50 Ω, 22AWG maximum 1500 feet, 14AWG maximum 10000 feet

T-tap wiring: The total length of all branches shall not exceed 40000 feet

Class A (Style 6/7) configuration: T-tap is not allowed, SLC input and output form a closed loop

2. Auxiliary Bus (SBUS)

SBUS is used to connect system expansion modules, including remote alarm (5860), LED alarm (5865-3/5865-4), LED driver module (5880), serial/parallel interface module (5824), intelligent power module (5496, 5895XL), etc.

SBUS wiring distance: The maximum total current is 1A, and the distance depends on the wire gauge and total current. For example, under a total current of 0.395A:

22AWG maximum 370 feet

18AWG maximum 938 feet

16AWG maximum 1493 feet

14AWG maximum 2362 feet

Key points for installation and wiring

1. Cabinet installation

The dimensions of the 5700 cabinet are 12.75 inches wide by 15.125 inches high by 3.375 inches deep. Attention should be paid during installation:

Avoid installing in locations that may be damp

Concrete walls should be installed with 3/4 inch plywood before fixing the cabinets

The conduit should enter from the side or bottom, and entering from the top can easily cause water vapor to enter

2. Wiring specifications

High voltage (AC power) and low voltage (SLC, SBUS, telephone lines) must be wired separately

Separate conduits should be used for different functional wires to avoid electromagnetic interference

Notification circuits, relay circuits, SLC loops, etc. should be routed along the inner edge of the cabinet to avoid crossing the circuit board

3. Battery connection

The batteries are connected in series to form a 24 VDC power supply. The battery cable (red positive black negative) needs to be connected correctly, as incorrect polarity can damage the panel. The RBB battery cabinet can be used to store larger capacity batteries, and the distance between the battery cabinet and the main cabinet should not exceed 18 inches.

Programming and Configuration

The 5700 control panel can be programmed through the front panel menu or the Silent Knight software suite (SKSS).

1. JumpStart automatic programming

JumpStart is the recommended programming method for initial system installation. After running JumpStart, the system will:

Scan SLC loop to identify all detector and module types

Create Zone 1 and assign all input points to Zone 1

Create an output group and assign the notification circuit to Group 1

Map Zone 1 to Group 1 (alarm events use constant light mode)

Assign relay 1 to Group 124 (for monitoring events)

Assign relay 2 to Group 125 (for alarm events)

Important note: JumpStart should only run once after the system is powered on for the first time and the SLC device completes address settings. After running, all manual configurations will be reset, so it cannot be repeated after the system has been configured.

2. Manual programming

The system supports up to 125 input zones and 125 output groups. Programming options include:

Input point configuration:

Equipment types: photoelectric detector, ion detector, thermal detector, manual pull station, water flow switch, monitoring switch, etc

Regional allocation: Each input point can be assigned to a region

Locked/unlocked: The locked point needs to be manually reset, while the unlocked point automatically recovers

Muteable/Unmute: determines whether the point can be suppressed by pressing the mute button

Output group configuration:

Output modes: constant light, continuous, ANSI 3.41, UL encoding, etc

Muteable/Unmute: determines whether the output of the group can be muted

Locked/unlocked: determines whether the output will automatically reset after the condition is restored

Reverse polarity: used for remote station applications

Regional event mapping:

Each region can map 11 types of events (manual pull station alarm, water flow alarm, detector alarm, pre alarm, monitoring, fault, CO alarm, etc.), and each event can activate up to 8 output groups or output group templates.

3. User access code

The system supports up to 20 user profiles:

Configuration File 1 (Firefighter Key): Read only permission, can perform specific functions (such as fire drills)

Configuration file 2 (installer code): highest authority, factory default 123456

User Profile 3-20: Customizable Name, Code, and Function Permissions (System Reset, Mute, Confirm, Point Function, Programming, etc.)

Operation mode and system behavior

The 5700 control panel can operate in multiple modes during operation:

Mode triggering condition system behavior

Normal, no alarms, no faults, no monitoring. The green power LED is always on and displays a custom banner

Alarm detector alarm, manual pull station activation DACT dialing, continuous local buzzer sound, red alarm LED flashing, notification circuit activation

Monitoring switch activation (such as water flow pressure monitoring) DACT dialing, buzzer pulse sound (1 second on/1 second off), yellow monitoring LED flashing

System malfunction (battery, SLC open circuit, AC power failure, etc.) DACT dialing, buzzer pulse sound (1 second on/9 seconds off), yellow fault LED flashing

Pre alarm 2-Count: A single detector in the area will sound the local buzzer, and the output group can be programmed to activate without reporting to the central station

Silent alarm or fault has been muted but the condition has not been restored. The system mute LED is on, indicating that the circuit is silent and the LED remains lit

After pressing the reset button, all LEDs briefly light up, and the system resets the detector to restore normal operation or re-enter the alarm state

Releasing Operations

The 5700 control panel supports single interlock and double interlock release systems, suitable for applications such as pre action fire extinguishing systems and rain shower systems. The release function must be equipped with a 5496 intelligent power module.

1. Single interlock release

Pre alarm output activation condition: Any addressable detector activated

Alarm and release output activation conditions: Two or more addressable detectors activated, or manually released switch activated

2. Double interlocking release

2. Common troubleshooting

Possible causes and solutions for the fault phenomenon

DBL ADDR "displays multiple devices using the same address and re addressing according to the correct process

SLC equipment missing wiring errors, polarity errors, address not set check polarity, address, loop impedance

Auxiliary power supply polarity error, wiring error, correct wiring: When an alarm is triggered, the terminal with "X" is positive

The circuit impedance exceeds the standard. If the cable is too long or there are too many T-taps, the measured impedance should be>500k Ω (open circuit) and<50 Ω (short circuit)
