• Level 2—Smoke concentration reaches the second setpoint, and the VESDA system indicates that a fire
exists in the HP POD 20c and sends an activation signal to the fire suppression system.
IMPORTANT: The VESDA filter must be changed regularly to ensure accurate smoke detection
readings. For more information about changing the VESDA filters, see the HP Performance
Optimized Datacenter 20c Maintenance and Service Guide.
(Optional) Fire protection system
Each HP POD 20c is equipped with a fire alarm panel that is integrated with the fire detection system and the
optional fire suppression system.
The fire system is designed as a stand-alone system, but can also interface with customer site fire alarm
systems. Customer site connections are the responsibility of the customer. Consult with HP for connection
locations.
The fire protection system includes:
• Manual fire pulls (on page 19)
• Fire alarm indicators (on page 19)
• Fire suppression system (on page 19)
Manual fire pulls
The HP POD 20c includes one fire pull that is located next to the personnel access door.
Manually activating a fire pull does the following:
• Activates the POD fire alarm system horn and strobe lights
• Triggers a fire alarm signal to the BMS in the fire box and activates a 30-second delay before releasing
the fire suppression agent
IMPORTANT: The fire suppression abort button will not delay the release of the fire suppression
agent if a manual fire pull is initiated. All personnel should evacuate immediately.
Fire alarm indicators
Upon activation of a fire alarm within the HP POD 20c, the following alarms alert personnel:
• Strobe light—The HP POD 20c includes one internal fire strobe light located in the cold aisle.
• Audible horn—The HP POD 20c includes one horn located in the cold aisle.
• Alarm within the ECS—The ECS system notifies you of a fire alarm condition with an alarm alert on the
ECS screen.
Fire suppression system
WARNING: Fire suppression agents include a pre-discharge warning and evacuating system. In
the event of a fire, all protected space must be evacuated as soon as possible.
