Open Delivery Alarm Testing Apparatus

An open delivery alarm testing apparatus comprising:

• an elongated lower shaft produced from a rigid polymeric material positioned about a longitudinal axis and having a first end and a second end having an opening, the elongated lower shaft having an overall length greater than 24 inches (61 cm);
• an upper shaft produced from a rigid insulating material having a shorter length than the lower shaft, the upper shaft having a distal end and a proximal end, the distal end having a smaller cross-sectional area than an adjacent portion of the upper shaft such that an abutment is formed between the distal end and the adjacent portion, the distal end fit within the opening in the second end of the lower shaft such that the abutment engages the lower shaft and is joined to the lower shaft by an attachment means including a spring-loaded keeper extending radially outwardly from the distal end of the upper shaft and engaging a portion of the lower shaft to retain the upper shaft to the lower shaft;
• a spring-loaded activator produced from a rigid insulating material extending from the proximal end of the upper shaft, the activator having a rod inserted within the proximal end of the lower shaft and extending outwardly therefrom and a beam member extending outwardly from the rod substantially perpendicular to the longitudinal axis biased in an upward position by a spring member;
• a bracket fixedly attached to the upper shaft for attaching a container thereto;
• and
• a testing container attached to the upper shaft by the bracket and filled with a testing substance stored under pressure within the testing container, the testing container having a pressure relief valve positioned by the bracket proximate a lower surface of the beam member of the spring-loaded activator and engageable therewith on a downward force placed on an opposing upper surface of the activator.
