4.0Specifications

Power:

D296

18 to 32 VDC Receiver: 45 mA @ 24 VDC, Transmitter: 20 mA @ 24 VDC

 

D297

10.2 to 18 VDC Receiver: 50 mA @ 12 VDC, Transmitter: 20 mA @ 12 VDC

Alarm Output:

 

One Normally Open (NO) Contact rated 1 A, 60 VDC maximum for resistive loads. One

 

 

Auxiliary Form “C” (NO/C/NC) contact rated 1 A, 60 VDC maximum for resistive loads.

Tamper/Trouble Output:

One Normally Closed (NC) Contact rated 1 A, 60 VDC maximum for resistive loads. Opens

 

 

when the cover is removed, power is lost or the beam is blocked.

Signal Processing:

Automatic Signal Synchronization eliminates the need for a synchronization wire. Self-

 

 

compensating circuitry compensates for signal loss due to dust or dirt buildup on lens and

 

 

signals a trouble condition upon signal loss of 50%.

Operation:

 

The transmitter emits an invisible pulsed infrared beam to the receiver. If the beam is obscured

 

 

beyond the selected threshold by smoke, the receiver signals an alarm. If the beam is

 

 

completely blocked, the receiver signals a trouble.

Alarm Response Selectivity:

Eight (8) sensitivity settings are available. Selectable response time of 5 or 30 sec.

Storage & Operating Temperature: -22°F to +130°F (-30° C to +55°C). For UL Certificated Installations +32°F to 120°F (0°C to

 

50°C).

Test Features:

Externally visible LEDs on transmitter and receiver give indication of signal, alarm, and

 

supervision conditions. Signal voltage output on receiver assists in alignment and

 

troubleshooting. D306 Indicator Plate (included) provides LED indication of the detector’s

 

status/condition, and provides a point to read/test the signal voltage.

Dimensions (H x W x D):

7 in. x 5.5 in. x 5.5 in. (17.8 cm x 13.9 cm x 13.9 cm)

Coverage:

30 to 350 ft (9 m to 107 m) range, up to 60 ft (18 m) spacing on smooth, flat ceilings.

Mounting:

Surface or ceiling mount to standard 4 in. / 10.2 cm square or octagonal electrical boxes.

Pattern Pointability:

Internally pointable ±90° horizontal, ±10° vertical.

Radio Frequency Interference

No alarm or setup on critical frequencies in the range from 26 to 950 Megahertz at 50 v/m.

(RFI) Immunity:

5.0 Accessories

 

Standard:

 

D306 Remote Indicator Plate. This standard accessory provides a status monitor of the condition of the beam smoke detector and allow for a calibration voltage measurement to determine if the detector is within the calibration range. The D306 may be mounted to a standard single gang box.

Optional:

D307 Remote Test/Indicator Plate. This optional accessory provides a status monitor of the condition of the beam smoke detector and allow for a calibration voltage measurement to determine if the detector is within the calibration range. Remote test and detector reset can also be performed from the plate using a keylock switch. The D307 may be mounted to a standard double Wiremold box.

D309 Alignment Strobe. This optional accessory provides a visual indication to assist on the alignment of the D296 transmitter and receiver.

D1005 Test Cord. This optional accessory provides an electrical connection to the D296 receiver to assist in the alignment of the receiver and transmitter.

D308 Field Test Kit. This optional accessory allows testing the calibration of the D296 Series Beam Smoke Detectors by providing a calibrated amount of obscuration between the transmitter and receiver.
