Operating Voltage : 14 – 28 VDC

Standby Current : 10 mA – 16 mA @ 24VDC (low current mode, depends on the number of detector heads)

Alarm Current : 50 mA @ 24VDC (high current mode)

Remote Indicator : Low-level remote indicator and control unit with LCD display; supports up to 4 detector heads for installation, reporting and testing

Test Button : Test and acceptance are provided by the built-in electronic obscuration acceptance test (UL/ULC/FM approved)
