摘要 A preferred embodiment alarm device for use with fall protection equipment includes an elongating member, an alarm, an activation member, and a connecting member. The elongating member has a first end and a second end and extends in length as the first end and the second end are pulled in different directions. The alarm is operatively connected to the first end of the elongating member, and the activation member is releasably connected to the alarm. The activation member activates the alarm when disconnected from the alarm. The connecting member interconnects the activation member and the second end of the elongating member, and the activation member becomes disconnected from the alarm when the elongating member is extended in length as the first end and the second end are pulled in different directions thereby activating the alarm when the elongating member is extended.
