Asenware AW-CSH832-4W 4-Wire Conventional Smoke and Heat Combined Detector with Strobe and Buzzer

The AW-CSH832-4W is a 4-wire conventional detector combining smoke and heat detection in a single housing, equipped with strobe and buzzer. While the photoelectric optical chamber evaluates combustion product particles, the heat channel monitors temperature rise; in an alarm condition, the detector's own audible and visual warning activates without waiting for the siren at the panel. On the power supply side, it operates over a wide voltage range of 40-60 VDC and thanks to its non-polarize terminal structure insensitive to reverse connection, cable direction confusion does not affect installation; SMT manufacturing and the metal shield inside the housing provide protection against electromagnetic interference. A 360° dual LED visible from all directions gives periodic flashes during normal operation to indicate power presence; in warehouses and technical spaces where the detector is not in direct view, a second LED can be carried outside the door via a 2-wire remote indicator output.
