Description
Kidde Fire Systems offers four models of the Nitrogen Time Delay that are matched to the 108 cu. in. and 1040 cu. in. nitrogen pilot cylinders. Each unit is individually rated to meet the code* requirement of -0%/+20% from 32°F to 130°F (0°C to 54°C). The delay period is longest at the lowest operating temperature and shortest at the highest operating temperature. Therefore, the rated value of the nitrogen time delay relates to high temperature performance, i.e., the delay period at 70°F (21°C) is longer than the rated delay for each unit.
