Conventions
Circuits
Refers to a physical electrical interface for the analog loop, indicating signals or relays, and common alarm,
supervisory, and trouble relay outputs.
Zone/Group
Is a logical concept for a Fire Alarm Protected Area, and will consist of at least one Circuit. Groups are used to
facilitate bypassing of inputs and outputs.
Display Points
The SFC-500 provides an LCD display to annunciate the status of the system and connected devices.
Wiring Styles
The analog loop can be connected in Class B (Style Y) or Class A (Style D) configurations. Changing the indicating
circuits to Class A requires an SOCA-204 adder board which will convert four indicating zones from Class B (Style
Y) circuits to Class A (Style Z). This is done without reducing the number of circuits.
Note: The Model SFC-500-60DR panels DO NOT recognize any devices with addresses higher than 60.

Circuits and Devices
Addressable/Analog Devices
The SFC-500 supports one loop of addressable/analog devices. The device loop can be used to connect up to 60 or
126 analog devices and addressable input or output modules on an unshielded twisted pair (UTP). The devices
must be compatible with the Summit device protocol.
The loop interface software continuously supervises the devices on its loop against those found during configuration
for the following conditions:
• device missing
• unconfigured device responding
• two or more devices responding to the same address
• wrong device type
A communication or addressing error on a device is reported as a trouble on the associated zone LED if configured.
The addressable loop can be configured for class A or B operation. "T-tapping" is allowed (Refer to device
installation documentation for details). A short or open on the loop will activate the common trouble sequence with a
latching trouble.
Devices on the loop have an optional LED which normally flashes when the device is polled and goes ON steady
when the device is active (alarm for an input device or active for an output device). The flashing of the LED on
polling for sensors can be suppressed during configuration. For input or output modules, the LED always flashes
when polling. The software limits the maximum number of the devices which can have their LED turned ON when
active to fifteen (15).
Certain devices are designed to support an optional external LED, which operates when the LED on the device is
activated. Remote/external LEDs must NOT be used on this system. The panel can provide up to 350mA of current
to the devices on the loop. A maximum line loss of 5 volts is permitted, so the loop distance, wire size, and
maximum number of devices are limited by this constraint. The device currents are as follows:
The devices should be installed using unshielded twisted pair (UTP). The currents above may be used to calculate
the total line drop on the loop, which must not exceed 5 volts worst-case at the last device. The calculations
required to determine the maximum permissible loop wiring distance with various combinations of devices is
relatively complicated, and when isolators are used, includes a consideration of device inrush currents which must
not exceed 20mA for a single isolator. In no case should more that twenty devices be connected to a single isolator.
To simplify the calculation process, please utilize the loop calculator program located on the Summit website at
http:/www.summit-st.net in order to determine maximum loop lengths, number of devices, and wire sizes etc.
It is also important to note that the device LEDs present a significant extra load on the loop which must be
considered in calculating permissible loop lengths, battery capacities, etc. Please refer to the device Installation

information. The system will automatically limit the maximum number of device LEDs which can be illuminated
to 15.
Analog Devices
The system supports Summit SI-200 Series photo, ion, and thermal (heat) type analog detectors, as well as contact
input and output devices. The detectors may be configured as non-verified or verified alarm inputs. To determine an
alarm condition, the system polls the analog device and compares the analog value against stored thresholds for pre-
alarm and alarm conditions.
A range of thresholds is provided for each type of analog device (except for contact devices), corresponding to the
agency approved range of threshold for a particular device type. Each device can be individually configured to a value
in the range of threshold for “day time” and one for the “night time” or after hours operation; i.e. a device may be
configured to a low sensitivity for “day time” and high sensitivity at “night time”. The day time threshold will be used
unless the after hours operation is active.
Drift Compensation
The SFC-500 will automatically adjust for gradually increasing affects of dust and other accumulations of dirt in the
detectors. It will adjust the thresholds to compensate for a detector going dirty according to the gradual change in the
normal clean air value received. When it can no longer compensate for an increasingly dirty detector, a dirty detector
trouble is indicated for that device.
Auto Test
Periodically each detector is commanded to return an alarm value to test its ability to alarm. If it fails the test, a trouble
is indicated on that device. This trouble is latched until system reset.
Contact Inputs
Contact input modules on the addressable/analog device loop may be configured as any of the following input types:
• non-verified alarm inputs
• waterflow inputs
• non-latching supervisory inputs
• latching supervisory inputs
• monitor inputs
• trouble only inputs
• remote switch inputs
Contact Outputs
Contact output modules on the addressable/analog device loop may be configured as any of the following output types:
• signals
• strobes
• relay outputs
Analog devices may be installed with relay or sounder bases. The outputs of these bases are activated when the
device active LED turns ON steady in response to an alarm. The command to activate the output is separate from the
command that activates the LED and they are not subject to the same restrictions as the LED. Output modules
configured as signals are not stroked by software at the current signal rate. When the system commands them to
be either in alert or in evacuation, the panel will simply activate them continuously. It is possible to provide stroked
operation by connecting the signal power to a conventional signal output which is stroking at the correct rate when the
device is active. Depending on the device, the system can detect open and short troubles and report it as an output
circuit trouble.

Loop Isolators
To limit the number of addressable devices compromised by a short on the addressable loop, isolators (SIM-100X,
100XH, or 100XB) may be used to isolate the affect of the short circuit. If the impact of a short circuit must be limited
to only one device, an isolating base must be used for each detector. A maximum of twenty devices can be
connected between isolators, or between the panel and the first isolator, as long as the maximum in-rush current for
the devices on one segment of the loop does not exceed 20mA. Refer to the installation instructions for
