as a guide to help determine how heavily loaded an SBUS is with respect to bandwidth. We recommend you use
this tool if you plan to have more than eight SBUS devices per SBUS. Remember to include devices that are on
5859XL SBUS repeaters in your list of devices for SBUS bandwidth calculations.
4.14 Telephone Connection
Connect the telephone lines as shown in Figure 4-44. The Model 7860 phone cord is available from Honeywell
Silent Knight for this purpose. A number of programmable options are available for customizing telephone lines.
These options are described in Section 9.6.

4.15 Flexputs
™
I/O Circuits
The two Flexput™ circuits are an innovative and versatile feature of the control panel. They can be used as:
Class A or B notification circuits, Class A or B initiation circuits (either 2 or 4 wire detectors), or as auxiliary
power (resettable, continuous, door holder, or sounder base sync).
The polarity of the Flexput terminals differs depending on whether the circuit is programmed as an input or an
output circuit. If the circuit is programmed as an input circuit (for a detector or normally open contact) the X
terminal is negative and O terminal is positive. If the circuit is programmed as an output circuit (Aux power or
NAC) then the X terminal is positive and the O terminal is negative.
This section of the manual explains how to install conventional notification appliances and initiating devices to
be used with the system.
Note: For Flexputs used as NAC circuits refer to Section 4.16
4.15.1
Conventional Input Switch Circuits
This section of the manual explains how to install conventional initiating devices for Class A or Class B
configurations.
4.15.1.1 Class B Inputs
You can connect conventional Class B switches, such as waterflow switches and pull stations, directly to the
Flexput circuits of the control panel.
To install a Class B switch:
1.
Wire the Class B switch as shown in Figure 4-45.
