Source of Supply/Master Alarm Test
Master alarm panels are verified to be on a dedicated circuit breaker and connected to the essential electrical system. The master alarm panel is verified to operate independently of all other alarm systems in the healthcare facility including computer-controlled alarm systems. The location of the master alarm panel is checked to ensure it is in an area continuously and responsibly surveilled.
All pressure switches in the sources of supply are calibrated and their operation verified. All sources are verified as having one main shut-off valve and that the mainline pressure or vacuum switches are downstream (on the user side) of that valve. All alarms are simulated. Supply changeover from primary to secondary and emergency supplies is performed, and their associated warning alarms are verified.
Pump packages are inspected to ensure that each pump can be totally isolated for service without affecting the operation of the remaining pump(s). The correct alternation of the pumps as well as the cut-in and cut-out set points for each pump are tested and verified. Related pressure switches are calibrated and their operations verified. Alarm points associated with each pump package are verified. Medical air reserve cylinder extension leads are checked for proper flexibility, metal fatigue and thread damage to the cylinder connection. Non-return valves for medical air reserve cylinders are checked for proper closure.
