Pass Device

The PASS device on the G1 SCBA is made up of three components: control module, power module, and battery module (alkaline, rechargeable). The PASS device monitors movement through a motion sensor. When a user is motionless for 20 seconds, the PASS device goes into pre-alarm. After 30 seconds, the PASS device goes into full alarm to alert those around the user. The PASS device also monitors cylinder pressure and battery status.
