Telephone Connection; Flexputs ™ I/O Circuits; 1: Conventional Input Switch Circuits; Class B Inputs - Honeywell Silent Knight SK318PT Installation And Operation Manual

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.
™ I/O Circuits
4.15 Flexputs
The two Flexput™ circuits are an innovative and versatile feature of the control panel. They can be used as: Class A or B notification cir-
cuits, 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 cir-
cuit 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.

Class B Inputs

You can connect conventional Class B switches, such as waterflow switches and pull stations, directly to the Flexput circuits of the con-
trol panel.
To install a Class B switch:
1. Wire the Class B switch as shown in Figure 4.45.
