D7050DH | Installation Instructions | 1.0 Description

Notices

These instructions cover the installation of the D7050DH Multiplex Photoelectric Duct Smoke Detector on a D7024 or a DS9400M 24 VDC Fire Alarm Control Panel (FACP) with a D7039 or DS9431 Multiplex Expansion Module installed. The D7024 and DS9400M requires ROM version 2.0 or greater.

Install, test, and maintain the D7050DH according to these instructions, NFPA 72, local codes, and authority having jurisdiction (AHJ).

Follow the procedures in these instructions to avoid personal injury and damage to the equipment. Failure to follow these instructions can result in the D7050DH not operating properly. Bosch is not responsible for improperly installed, tested, or maintained devices.

The D7050DH complies with Part 15 of the Federal Communications Commission (FCC) Rules and with the RSS-210 of Industry and Science Canada.

D7050DH operation is subject to the following two conditions:

1.It does not cause harmful interference.

2.It must accept any interference it receives, including interference that might cause undesirable operation.

1.0Description

The D7050DH (Figure 1) is Underwriters Laboratories, Inc. (UL) Listed and requires a D343 Duct Detector Housing. Use this detector with the D7024 or a DS9400M that includes a D7039 or DS9431 Multiplex Expansion Module.

An LED indicator on the head flashes every 3 to 8 sec to ensure the D7050DH has power and the smoke sampling circuitry functions. This LED flashes at least once each second during an alarm confirming individual detector alarms. The D7050DH automatically resets after the alarm condition clears.

2.0 Installation

For installation details, refer to the D7024 FACP Operation and Installation Guide (P/N: 31499), the D9400M Reference Guide (P/N: 44578), the D7039 Installation Guide (P/N: 38685), or the DS9431 Installation Instructions (P/N: 41381).

Do not exceed the maximum line resistance of 50Ω .

4.0 Setting the Address

Set the D7050DH address before connecting to the control panel and applying power. The address number is the same as the input point or zone number.

Set the D7050DH’s address using a flat-blade screwdriver to position the rotary switches

(Figure 3) located on the back. Note that the switches click when turned.

The valid address range is from 009 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.

1 - Hundreds					2 -	Tens		3 -			Ones

A = D7024 FACP, B = DS9400 FACP

For example:

0 hundreds, 9 tens, 5 ones = Address 95 on the D7024 FACP

The A address range works on the D7039 Multiplex Expansion Module with the D7024 FACP. The B address range works on the DS9431 Multiplex Expansion Module with the DS9400M FACP.

Figure 3 shows the A address range set at 095, allowing the D7039 to work with the D7024 FACP.

5.0 Mounting

1.Remove the tamper screw located in the recess on the top of the dust cover.

2.Remove the dust cover.

3.Mount and wire the duct housing according to the

D343 Installation Instructions (P/N: 48199).

4.Mount the D7050DH to the base by turning it clockwise until it clicks into place (Figure 4).
