Notices

These instructions cover the installation of the D7052 Multiplex Dual Input Module in a fire system supervised by a D7024 or DS9400M Fire Alarm Control Panel (FACP) with firmware revision 2.0 or greater and a D7039 or DS9431 Multiplex Expansion Module.

Install, test, and maintain the D7052 according to these instructions, NFPA 72, local codes, and the Authority Having Jurisdiction (AHJ).

Follow the procedures in these instructions to avoid personal injury and damage to equipment. Failure to follow these instructions can cause the D7052 to not operate properly. Bosch is not responsible for improperly installed, tested, or maintained devices.

Test the FACP according to NFPA 72.

1.0Description

The D7052 (Figure 1) is a general purpose module that connects to the multiplex bus of the control panel. It provides two supervised Class “B” input zones or one Class “A” input zone. Use a jumper pin setting for a Class “A” or Class “B” wiring configuration.

All operating power for the D7052 is drawn from the control panel. Rotary switches provide convenient address setting.

An on-board Status LED, visible through the faceplate, indicates normal operation and communication with the control panel. The LED flash rates are:

•Fast: Approximately 4 sec indicating an alarm condition.

•Medium: Approximately 8 sec indicating a normal operation.

•Slow: Approximately 16 sec indicating a trouble condition.

The D7052 can be mounted in a standard double-gang or a 4 in. x 4 in. electrical box.

2.0Setting the Address

Set the D7052 address using a flat-blade screwdriver to position each rotary switch located on the front of the module (Figure 2). Note that the switches click when turned.

Figure 2: Setting the Address
	0 1 A	9	0 1	9	0 1
	2	8	2	8	2
	0	7	3	7	3
	2 1 B	6 5 4		6 5 4
	1		2		3
1 -	Hundreds	2 -	Tens		3 -	Ones
	A = D7024 FACP, B = DS9400M FACP
For example:
0 hundreds, 9 tens, 5 ones = Address 095 on the
			D7024 FACP

The valid address range is 9 to 255. Refer to the D7024 Operation and Installation Guide (P/N: 31499) or the

DS9400M Reference Guide (P/N: 44578) for additional address limitations.

The D7052 requires two program addresses. The address cannot be 8 or a multiple of 8, such as 16, 24, 32, and so on.
