EN Installation Instructions Multiplex Photoelectric Duct Smoke Detector D7050DH D7050DH | Installation Instructions | 1.0 Description 2 Bosch Security Systems, Inc. | 9/06 | 49325E 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. 1.0 Description 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).

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.

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).

D7050DH | Installation Instructions | 6.0 Programming 4 Bosch Security Systems, Inc. | 9/06 | 49325E 6.0 Programming For multiplex programming, refer to the D7024 FACP Operation and Installation Guide (P/N: 31499) or the DS9400M Reference Guide (P/N: 44578). 7.0 Testing Test detection devices immediately after installation. Test the D7050DH according to NFPA Chapter 7-1.6.2 (1999) or more often as required by local code. 7.1 Operational Testing Notify all concerned parties before and after completing maintenance on or testing the fire alarm system. 1. Apply power to the system and check for alarms. 2. If a D7050DH is in alarm, shut down the system. 3. Remove the D7050DH and recheck for proper wiring. If the problems persist, replace the affected D7050DH or exchange it with a known good detector. This determines if the problem is caused by the D7050DH. 4. When the system is free of alarms, check each D7050DH to ensure the red LED indicator on the head flashes. This confirms the detector is operating properly. 5. Test each D7050DH to ensure it causes a control panel alarm. 6. Alarm the D7050DH by doing one of the following: a. Place a magnet horizontally against the recess in the duct cover, centering it over the “T” marked on the head to activate an internal reed switch. b. Remove the duct cover and use a UL Listed aerosol smoke detector tester such as the Home Safeguard Industries’ 25S to simulate an alarm. Follow the instructions included in the aerosol smoke detector tester. 7. When a D7050DH alarms, the red LED indicator on the head flashes at least once per second. Clear the alarm by initiating a system reset before proceeding to the next detector. 7.2 Sensitivity Testing Calibration is important in determining a detector’s continued operation. Depending on local regulations, calibration testing might be required more than once a year. According to NFPA72, perform a Calibration Test at installation and every other year thereafter. Perform a Functional Test monthly. Test the D7050DH’s sensitivity to meet NFPA 72 requirements by conducting a Magnet Test (refer to Section 7.3 Magnet Test). You can also test sensitivity by measuring the calibration voltage pins with D1005 Test Cable, D344-RL, or D344-RT (refer to Section 7.4 Voltage Measurement Test). Calibration can be quickly determined by visually inspecting the D7050DH’s LED (refer to Section 7.2.2 Visual Check). These tests confirm whether or not the detector is within its factory marked calibration range. 7.2.1 Sensitivity Test The control panel constantly monitors the D7050DH. If the detector exceeds the limits of the sensitivity thresholds, the control panel reports the detector in question and generates a fault condition. 7.2.2 Visual Check The D7050DH includes the Chamber Check Automatic Trouble Indication that allows it to automatically show if its calibration is out of the factory-listed range. You can meet the NFPA guidelines for sensitivity testing by visually inspecting the D7050DH and checking the Alarm LED flash rate. If the calibration is out of range during power up or longer than 24 h, the Alarm LED double flashes. This LED single flashes when the detector is operating normally. Visually check all detectors before disconnecting the multiplex bus. Disconnecting the bus erases the calibration indication. If the detector was disconnected or the control panel lost power within the last 24 h, perform a Magnet Test or Voltage Measurement Test to confirm sensitivity.
