EPO accidental activation
To help prevent accidentally pressing the EPO button and activating the EPO system, each EPO button is
covered with a clear Lexan cover.
Battery backup during an EPO event
The following components are equipped with a UPS to ensure that service is not interrupted during a loss of
power to the HP POD 40c G2:
• ECS system
• VESDA air sampling smoke detection system
• Optional fire suppression system
• Emergency lighting in the HP POD 40c G2
Fire protection system
Each HP POD 40c G2 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)
• VESDA air sampling smoke detection system (on page 19)
• (Optional) Fire suppression system (on page 20)
Life safety systems 19
Manual fire pulls
The HP POD 40c G2 includes two fire pulls. One fire pull is located next to the personnel access door and
the second fire pull is located next to the emergency exit.
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 (on page 63) 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 40c G2, the following alarms alert personnel:
• Strobe lights
o Internal—The HP POD 40c G2 includes one fire strobe light located in the cold aisle.
o External—The HP POD 40c G2 includes one fire strobe light located at the standard personnel entry
door.
o Optional—There is an additional fire strobe light located in the cold aisle that can be connected to
the site fire alarm system at the expense of the customer.
• Audible horn—The HP POD 40c G2 includes two integrated horns. One horn is located on the internal
strobe light and the second horn is located on the optional strobe light.
• Alarm within the ECS—The ECS system notifies you of a fire alarm condition with an alarm alert on the
ECS screen.
VESDA air sampling smoke detection system
CAUTION: Excess dust within the HP POD 40c G2 can cause the VESDA smoke detector to
trigger a fire alarm.
The VESDA system features a single zone laser scan early warning smoke detector to provide the earliest
warning of a potential fire.
The orange VESDA conduits that run throughout the HP POD 40c G2 include inlets for smoke sampling. The
VESDA uses a high-efficiency aspirator to continuously draw in air from the HP POD 40c G2 and circulate
the air through a dual-stage filter:
• Stage 1—Dust and dirt are removed from the air sample.
• Stage 2—Remaining contaminants in the air sample are removed with an ultra-fine filter.
After the air passes through the dual-stage filter, it enters a calibrated detection chamber where a laser scans
the air sample for the presence of smoke. When the smoke concentration reaches the first setpoint, the
VESDA system will send an alarm signal indicating that a fire might exist. When the smoke concentration
reaches the second setpoint, the VESDA system indicates that a fire does exist in the HP POD 40c G2 and
sends an activation signal to the fire suppression system.
Life safety systems 20
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 40c G2 Maintenance and Service Guide.
(Optional) Fire suppression system
CAUTION: The POD fire suppression system is manufacturer designed, engineered, and
installed to comply with national standards. However, HP does not certify that the installed fire
suppression system meets all local jurisdiction requirements. Compliance with local codes is your
responsibility, and includes specific local requirements for initial and periodic inspections,
certifications, and maintenance.
Any additional local requirements are not covered as part of the option price or basic installation
and deployment services, unless specifically included in an executed Statement of Work.
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.
IMPORTANT: The fire suppression abort buttons that are located next to each personnel door
can be pressed to interrupt the 30-second fire suppression agent release delay for an additional
30 seconds. This button interrupts the countdown, but does not reset the 30-second fire
suppression agent release delay. The fire suppression agent release countdown will continue
when the abort button is released until the time is exhausted and the fire suppression agent is
released.
The fire suppression system contains conventional fire alarm control circuits and includes features required
for single or dual-hazard suppression release applications, including a low-toxicity agent. In the event of fire
suppression release, the suppression tanks must be refilled by a certified technician.
Fire system operator panel
The panel is configured by the manufacturer in accordance with the local fire marshal and fire code
requirements.
The operator panel includes the following:
• Alarm status LED
• Trouble status LED
• Input status LED
• Output status LED
• Acknowledge button
• Alarm Silence button
• System Reset button
The fire system and panel are tested by the local certified fire system supplier and witnessed and certified by
the local AHJ or fire marshal.
The fire system operator panel requires regular maintenance and service. For more information on the fire
system operator panel component, see the Operation and Maintenance Manual for the HP Performance
Optimized Datacenter 40c G2.
