Designed to provide the earliest response to a wide range of fire types, the ZP732-2P POLAR WHITE dual detector combines optical smoke sensing and thermal monitoring to provide an accurate warning of fire. Individual software monitoring of each element measures actual smoke levels, in addition to temperature rates of rise. Smoke sensing can be isolated for areas where ambient smoke may exist at certain times of the day, or used on a day night basis in premises where heat only is required whilst the building is occupied.

Temperature response meets the requirements of EN54 Part 5 (Class A1 and A2), with smoke sensitivity complying with EN54 Part 7 and test procedure CEA4021. Several international approval bodies approved this detector.
