Smoke detector panel
The smoke detector panel contains an aspirating smoke detection system that draws air from the piping
network inside the HP POD and monitors the smoke levels in the air. If smoke is detected, the smoke
detector panel sends an alarm to the prewired Fire Alarm Control Panel.
No user interface settings are required. Interface is established through the Fire Alarm Control Panel.
For more information, see the product documentation included in the Operations and Maintenance
manual.
HP POD ECS panel
The HP POD ECS panel monitors the HP POD environmental conditions and determines optimum
operating conditions for the cooling system based on the existing load.
For more information, see Using the ECS (on page 35).
Electrical busway enclosed circuit breaker
The electrical busway panels are enclosed circuit breakers that provide over current protection to each of
the electrical busways. For more information, see Electrical busway enclosed circuit breaker (on page
31).
EPO Panel
IMPORTANT: If the remote powered 120V branch circuits are operational, they are not
turned off during an EPO shutdown.
The EPO panel contains controls and status lamps for the EPO system, which enables all power in the HP
POD to be turned off except for emergency lighting. Power to the EPO panel is single-phase 240V AC,
provided by the house panel.
Two EPO alarm buttons for directly shutting off non-emergency HP POD power are located inside the HP
POD, and one EPO alarm button is located on the outside of the HP POD.
To check that the EPO alarm buttons and alarms are functional, switch to Test mode and then press an
EPO alarm button. This procedure activates the EPO alarms without cutting off power to the HP POD.
