Applications
BH-500 is a point smoke detector for detection of
combustion gases mainly consisting of visible particles.
The detector has a built-in thermistor and is designed for
use with Autronica’s interactive fire detection systems,
which can provide temperature information from the
detector point. The SelfVerify function ensures the highest
grade of reliability because all units comprising this
function are tested with a calibrated test once every 24
hours.
The DYFI+ intelligence combined with the SelfVerify
functions and the allround smoke sensitivity of BH-500
makes this detector the obvious choice for demanding
applications such as industrial, maritime and offshore
installations. The additional PCB coating makes this
detector ideal in corrosive and humid environments.
Optionally there is a BH-500/N version for use in
hazardous area zone 2. It must be connected to the BSD-
310/N loop driver, but does not require an isolator/barrier
unit.
Principle
Photoelectric, operating on the light scatter principle.
SelfVerify: The detectors ability to initiate alarm at correct
amount of smoke is regularly checked.

Dimensions/Connections
Use of LED output
When LED or other equipment is connected to the LED output, a varistor - Siemens SIOVS07K25 (39V) -
Autronica part. no. 116-8464-003.5039, is required between terminals 1 and 4 in base.
The LED is connected between terminals 3 and 4, terminal 3 being the positive terminal.
