D321A-D324A/D336A | Installation Guide |

TrademarkWeatherban™ is a trademark of 3M Company.

NoticeThese instructions cover the installation of the D321A-D324A/D336A detection heads and bases in an analogsystem controlled by a D8024, D9024, or D10024Analog Fire Alarm Control Panel (FACP) using theadvanced digital transmission protocol.

Install, test, and maintain these devices according tothese instructions, NFPA 72, local codes, and theAuthority Having Jurisdiction (AHJ).

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

NFPA 72 requires a complete system-wide functional test be performed after modifying, repairing, upgrading, or adjusting the system’s components, hardware, wiring, programming, software, and firmware.

1.0 DescriptionIn an analog system, devices receive power andcommunicate with the FACP over the same circuit. TheBosch analog system uses two-piece detection devicescomprised of a detector base and an interchangeabledetector head.

The D321A Base (6-in. [15-cm] diameter) and theD336A Base (4-in. [10-cm] diameter) are compatiblewith the D8024, D9024, and D10024 Analog FACPs,the D322A Analog Heat Detector Head, the D323AAnalog Photoelectric Detector Head, and the D324AAnalog Ionization Smoke Detector Head.

The D321A and D336A can be installed in either aClass “A” (four-wire) or Class “B” (two-wire) analogpolling circuit. Both bases provide standard data in anddata out screw terminals and feature base securitylocking tabs to prevent tampering. The detector headsused with these bases are interchangeable and can beeasily removed for cleaning, servicing, or replacingwithout disconnecting the wiring.

The D322A provides property protection and is suitablefor use in high indoor ambient temperature, such askitchens, boiler rooms, or drying rooms. The D322Aalso accurately detects fast-flaming fires. Two LEDsflash each time the FACP polls the head (approximatelyonce every 18 sec) and latches on red when the head

goes into an alarm condition. Fixed temperatureactivation points for the D322A are programmable fromthe FACP. The default alarm threshold setting is +142°F(+61°C).

The D323A and D324A provide early warning fireprotection for life safety. The D323A is an analogphotoelectric detector head that senses dense smoketypically given off by plastic, foam, paper, wood, andother materials that tend to smolder. The D324A is ananalog ionization detector head suited for applicationsinvolving extreme humidity and temperature, andvibration. The D324A reacts best to small particulate-type smoke such as flare fires. This head also detectscertain invisible products such as flue gases.Additionally, the D323A and D324A detect fast-flamingfires.

Two LEDs on the D323A and D324A flash every timethe FACP polls the heads, approximately once every18 sec, and latch on red when the heads alarm.

2.0 Setting the Detector AddressEach analog detector head is assigned a specific addressthat is set by programming an EEPROM microchip. Itis not necessary to wire the devices to the FACP’spolling circuit in any particular order.

2.1 D5070 Analog Device Programmer

Use the D5070 Analog Device Programmer (Figure 1) to set the D322A, D323A, and D324A addresses before connecting them to the FACP’s polling circuit. Ensure the D5070’s battery is connected before programming.

Refer to Table 1 for a description of the D5070’sprogramming buttons.

3.0 Wiring the Detector Base

Before connecting or disconnecting a detector, remove all AC and battery power from the FACP. Failure to do so can cause personal injury or damage to the equipment.

Analog polling circuits connect to the FACP over two-wire cable. The bus protocol resists interference frommost types of electromagnetic interface (EMI) and radiofrequency (RF) generated noise. Under extremely noisyconditions, use twisted pair wire to reduce interference.Use shielded cable when EMI is a problem. Refer toTable 3 for shielded cable guidelines.

Table 3: Sensor Circuit Wiring Requirements

Nominal Capacitance 28 pF/ft (m) Typical Cable Resistance 3 Ω/1000 ft (305 m) Maximum Loop Resistance 25 Ω Recommended Maximum Loop Capacitance

Not to exceed 0.25µF

3.1 Guidelines

3.1.1 Data Circuit Length

Data circuit length is the distance over the circuit wirefrom the connection at the D9067 Polling CircuitModule to the most distant device and back to theD9067 Module. Data circuit length must include thedistance to any device connected to the circuit in aT-tap. Refer to Table 4 for polling circuit lengths andacceptable wire gauges.

Table 4: Polling Circuit Length and Wire Gauge

Polling Circuit Length Wire Gauge Up to 4000 ft (1219 m) 18 AWG (1.2 mm) 4000 ft to 7000 ft (1219 m to 2134 m)

16 AWG (1.5 mm)

3.1.2 Shielded Cable

If using shielded cable of good quality it should nothave a significant effect on the polling circuit length.Good quality shielded cable allows 0.25 µfd ofcapacitance, 1 mH of inductance, and 25 Ω resistance.

Connect the drain wire for shielded cable to the DataTerminal Block’s Terminal E inside the FACP (Figure 2).

An improperly grounded shielded cable can aggravate rather than eliminate noise problems. Reconnect the cable drain each time the cable is cut to install a device.

5.0 Base Security TabWhen you activate the base security tab you prevent anunauthorized detector from being removed.

1. Position the detector head so the bottom of thedetector head is facing up (Figure 9).

2. Break the tab using a small flathead screwdriver,allowing the base security tab to remain elevated toprevent the removal of the detector head.

To deactivate the base security tab so the detector hadcan be removed from the base:

1. Insert a small flathead screwdriver in the hole onthe outer rim of the detector head (Figure 10).

2. Rotate the detector head counterclockwise enoughto clear the base security tab while pushing down onthe tab.

3. Remove the detector head.

While pushing down on the base security tab only enough force to remove the detector head.

6.0 Testing the Detector HeadTest detection devices immediately after installation.Test smoke detectors according to Chapter 7 of NFPA72, or more often as required by local code.

A Smoke Test is the approved testing method for theD323A and the D324A. Use a D1002 Smoke Test Poleto perform a Smoke Test on the D323A and D324A.

NFPA regulations require a Calibration Test on thedetector. The D1002 does not meet NFPA requirementsfor a Calibration Test, but it does provide a simpleFunctional Test. For NFPA requirements, use the FACPas a calibrated testing device.

Test the D322A with a controlled heat source, not an open flame.
