HST-HD203B

The detector is plug-in type photoelectronic
smoke and heat sensors with addressable
analog communications. The sensors transmit an
analog representation of smoke density or
temperature over a communication line to a
control panel. Inside MCU’s EEPROM keep the
sensor’s address that can be set by a portable
Address setting device. Two LEDs on the sensor
are controlled by the panel to indicate sensor
status. The detector require compatible
addressable communications to function properly.
Connect these sensors to listed-compatible
control panels only.
