Installation Instructions

for the

DS7433 8 Input Module

1.0General Information

The DS7433 is an 8 input Module for use with the DS7400(Xi) Series Control/Communicator. It connects directly to the DS7400(Xi) and is designed to expand it to 16 hard wired points. One DS7433 may be used per DS7400(Xi) system.

•Current Draw: 65 mA Standby. 80 mA with one point in alarm. Add 15 mA per additional point in alarm.

•Maximum Loop Impedance: 60 ohms.

•End Of Line Resistor: 2.21 K ohm.

•12 VDC Nominal Operating Voltage.

2.0Installation

Warning:	Failure to follow the mounting instructions in this
	manual may result in damage to the DS7400(Xi)
	Control Panel.
Caution:	The DS7433 and DS7400(Xi) contain static sensitive
	components and must be handled with care. Follow
	anti-static procedures when handling the boards.

Stand-off “Ears” Board (PCB)

Stand-off

Be sure that the Stand-off is pressed firmly through the Printed Circuit Board, so that the Stand-off ears can expand outward.

•	Install the DS7433 board prior to installing the DS7400(Xi) board
	into the control enclosure. If the DS7400(Xi) board is already
	installed in the control panel enclosure, remove the 7400(Xi) board
	this time.
•	Place the DS7400(Xi) board on a flat surface with the component
	side of the module facing up.

•	Install the four plastic standoffs in the holes provided in the
	DS7400(Xi) module. Avoid bending or flexing the DS7400(Xi) board
	when inserting the standoffs. Be sure the standoff tabs are aligned
	so that they do not touch any components on the module. Be sure
	that the standoffs are firmly pressed into the board so that the
	“ears” can expand out. See drawings.
•	Install the DS7433 board onto the standoffs, noting that the
	connector pins from the DS7400(Xi) are properly aligned to install
	into the connector on the DS7433. Avoid bending or flexing the
	boards while pressing them onto the standoffs.
•	The DS7400(Xi) control board may be installed into the control
	panel enclosure at this time.

3.0 Wiring

Points 9-16 are intended for the connection of normally open or normally closed alarm contacts. These points may also be used with compatible 2 wire smoke detectors.
