A5366

Photoelectric Smoke Detector

with Interconnect and Timer

Features and Benefits

Description

▪ Low average standby current for long battery life

▪ Interconnect up to 50 detectors

▪ Piezoelectric horn driver

▪ Low battery detection (all internal)

▪ Chamber sensitivity test and alarm

The A5366 is a low-current BiCMOS circuit providing all of

the required features for a photoelectric type smoke detector.

Thisdevicecanbeusedwithaninfraredphotoelectricchamber

to sense scattered light from smoke particles. A networking

capability allows as many as 50 units to be interconnected so

that if any unit senses smoke all units will sound an alarm.

Special features are incorporated in the design to facilitate

calibration and testing of the finished detector. The device is

recognized by Underwriters Laboratories for use in smoke

alarms that comply with Standard UL217.

▪ Power-on reset (POR)

▪ Internal timer and control for reduced sensitivity mode

▪ Built-in circuits to reduce false triggering

▪ 6 to 12 V operating range

▪ ESD protection circuitry on all pins

▪ Temporal Horn Pattern, per UL217, NFPA72, and ISO8201

▪ UL Recognized for UL217 applications, per file #S2113

A variable-gain photoamplifier can be directly interfaced to

an infrared emitter-detector pair. The amplifier gain levels are

determinedbytwoexternalcapacitorsandareinternallyselected

depending on the operating mode. Low gain is selected during

standby and timer modes. During a local alarm, this low gain

is increased (internally) by approximately 10% to reduce false

triggering. High gain is used during pushbutton test and to

periodically monitor the chamber sensitivity during standby.

Packages:

16-pin DIP

(Package A)

Theinternaloscillatorandtimingcircuitrykeepstandbypower

to a minimum by sensing for smoke for only 100 μs every 10 s.

Aspecial three-stage–speedup sensing scheme is incorporated

to minimize the time to an audible alarm and also to reduce

falsetriggering. Chambersensitivityisperiodicallymonitored

andtwoconsecutivecyclesofdegradedsensitivityarerequired

for a warning signal (chirp) to occur.

16-pin SOICW

(Package LW)

TheA5366 is supplied in a 16-pin dual in-line plastic package

(suffix A), and for surface mount, a 16-pin SOICW (suffix

LW). The lead (Pb) free versions (suffix –T) have 100% matte-

tin leadframe plating. The devices are rated for continuous

operation over the temperature range of –25°C to 75°C.
