Life safety systems

Life safety overview

The HP POD 240e NA has multiple life safety systems that work together to protect the HP POD 240e NA equipment and personnel. The following life safety systems are included on the HP POD 240e NA:

• EPO system (on page 19)

• Fire detection system (on page 22)

• Emergency egress (on page 24)

• Facility connections to ECS ("Facility connections to the ECS" on page 35)

EPO system

If the HP POD 240e NA must be shut down during an emergency, the EPO system automatically powers off the HP POD 240e NA, activates the EPO indicator on the ECS panel door, and changes the EPO status light tree that is located on the POD exterior to red.

To be sure that all rack-mounted UPS devices are shut down during an EPO event, verify that each rack-mounted UPS device is connected to the HP POD 240e NA EPO system.

The EPO system can be activated two ways:

• Excessive high temperature in the hot aisle—The HP POD 240e NA includes two thermisters. If both

thermisters reach 60°C (140°F), an EPO shutdown is triggered automatically.

Side view

• Manual initiation—To manually trigger an EPO shutdown, press any of the EPO buttons. There are EPO

buttons located next to the personnel access doors in the POD. For the location of EPO buttons, see "Life safety component identification (on page 10)."

the HP POD 240e NA EPO system, to be sure that the UPS batteries are disconnected during an EPO event. For more information about connecting UPS devices to the EPO system, see the HP Performance Optimized Datacenter 240e NA Maintenance and Service Guide.

Life safety systems 21

Fire detection system

Each HP POD 240e NA is equipped with a fire alarm panel that is integrated with the fire detection system. The fire system is designed as a stand-alone system, but the system 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:

• VESDA air sampling smoke detection system (on page 22)

• Manual fire pulls (on page 22)

• Fire alarm panel (on page 23)

• Fire alarm indicators (on page 23)

VESDA air sampling smoke detection system

CAUTION: Excess dust within the HP POD 240e NA can cause the VESDA smoke detector to

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 piping that runs throughout the HP POD 240e NA includes inlets for smoke sampling. The VESDA uses a high-efficiency aspirator to continuously draw in air from the HP POD 240e NA and circulate the air through a dual-stage filter:

• Stage 1—A filter removes dust and dirt from the air sample.

• Stage 2—An ultra-fine filter removes remaining contaminants in the air sample.

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. The VESDA system cycles through two levels if smoke is detected:

• Level 1—Smoke concentration reaches the first setpoint, and the VESDA system sends an alarm signal

• Level 2—Smoke concentration reaches the second setpoint, and the VESDA system indicates that a fire

trigger a fire alarm.

indicating that a fire might exist.

exists in the HP POD 240e NA.

IMPORTANT: The VESDA filter must be changed regularly to be sure that smoke detection

readings are accurate. For more information about changing the VESDA filters, see the HP Performance Optimized Datacenter 240e NA Maintenance and Service Guide.

Manual fire pulls

The HP POD 240e NA has six fire pulls; two in each aisle. They are located in the life safety switch cabinet next to each personnel door of the HP POD 240e NA.

Manually activating a fire pull does the following:

• Triggers a fire alarm

• Activates the fire alarm system horn and strobe lights

Life safety systems 22

Fire alarm panel

The fire alarm panel is located in the control cabinet in IT section A and receives signals from the VESDA or manual fire pulls if an alarm condition exists. If an alarm condition does exist, the fire alarm panel activates the fire alarm indicators and sends a signal to the site fire alarm system, if installed.

The fire alarm panel also has a battery backup system that provides backup power to the fire detection system in the event of power loss to the HP POD 240e NA.

The control panel includes the following components:

• Alarm status LED

• Trouble status LED

• Input status LED

• Output status LED

• Acknowledge button

• Alarm Silence button

• System Reset button

Fire detection sequence of operations

There are two initiation sequences for the fire detection system, automatic (VESDA) initiation and manual initiation. The fire strobe light is activated by either initiation sequence.

The fire alarm horn will sound in a temporal mode for any VESDA or manual fire pull initiation. The fire system operator panel indicates which initiation sequence is active, using the indicator lights and a

panel alarm. These signals are also available to the site BMS system, if they are connected. VESDA initiation When smoke is detected, the VESDA fire detection system cycles through two levels, as described below.

• Level 1—Indicates the potential for a fire is present. The strobes illuminate and the horns sound.

• Level 2—Indicates that a fire exists. VESDA level 1 might have be reached; the strobes illuminate and

the horns sound. Manual initiation Manual initiation triggers the fire alarm, causes the fire strobe lights to illuminate, and sounds the horn.

Fire alarm indicators

Upon activation of a fire alarm within the HP POD 240e NA, the following alarms alert personnel:

• Strobe lights

o Internal—The HP POD 240e NA has three fire strobe lights; one in each aisle.

o External—The HP POD 240e NA has two fire strobe lights; one on each side.

• Audible horn—The HP POD 240e NA has three horns; located with the three internal strobe lights

• Alarm within the ECS

Bonding All structural sections of the HP POD 240e NA are bonded by connecting all metallic, non-current carrying

items throughout the HP POD 240e NA to protect from electric shock. If all steel-to-steel areas are bonded to one another, each object then has the same electrical potential which ultimately dissipates any high voltage or shock across the entire HP POD 240e NA, minimizing any effects from a lightning strike, per NFPA 70 in accordance with NEC (NA) and IEC (EMEA and APJ).

Lightning protection

The HP POD 240e NA structure and internal components are all bonded together. A common grounding electrode conductor connection point is provided. Proper bonding and grounding of the HP POD 240e NA minimizes the effects of a lightning strike. A surge protection device is provided on the HP POD 240e NA input connection to protect the HP POD 240e NA electrical system from voltage transients.

Environmental control system

Environmental control system overview

The ECS is a stand-alone control system developed for the HP POD 240e NA. The ECS does not require external connections with an external site system, BMS, public or private internet site, cloud, or wireless system to control the POD operation properly.

The ECS is designed to use Modbus TCP/IP connections to retrieve a variety of data. These capabilities connect to the stand alone ECS system to monitor the operating parameters of the POD at your expense. It is your responsibility (or your representative's or agent's responsibility) to integrate this communication capability into any existing BMS or monitoring system.

CAUTION: To be sure that alarm conditions can be identified and resolved, HP recommends that

you remotely monitor all alarm conditions. Failure to monitor the alarm conditions can cause delays in appropriate action during an alarm condition.

Using the ECS

HP recommends connecting the HP POD 240e NA to your facility BMS and establishing communication through the Ethernet cable connected to the external communications box. For more information, see "Configuring the ECS (on page 38)."

The HP POD 240e NA ECS is a Microsoft Windows-based system. The standard ECS protocol, Modbus TCP/IP, is a data communication protocol for building automation and

control networks. Connecting across different protocols might require additional engineering labor and coordination between your in-house control manufacturer and HP. It is your responsibility to make the connection between the HP POD 240e NA and a BMS system.

The ECS provides the following:

• A supported communication interface that can remotely monitor and control certain HP POD 240e NA

components.

• Immediate notification of all supported alarm messages.

By connecting your HP POD 240e NA to a BMS system, you can monitor the various parameters and alarms. For more information, see "Navigating the ECS interface (on page 42)." The complete list of parameters and alarms that can be monitored will be discussed with your facilities personnel.

IMPORTANT: If your site does not have a BMS, HP POD 240e NA ECS data can be sent to and

viewed from a set of IP addresses on a host computer. The ECS communicates through an Ethernet cable connected to the demarcation box (on page 67).

Environmental control system 34

Components of the ECS

The ECS system uses several of the POD components throughout the HP POD 240e NA to maintain the proper environmental conditions required within the HP POD 240e NA. The following components monitor and report information to the ECS:

• AHU

• Dampers and actuators

• Electrical system

• Exhaust fans

• Humidity sensors

• Pressure sensors

• Temperature sensors

Satellite control boxes

The satellite control boxes are used as connection points for communication from the environmental sensors back to the ECS control panel. Each satellite control box is configured for a different purpose, depending on the needs of the IT equipment communicating through it.

The HP POD 240e NA has six satellite control boxes. Top view shown

Facility connections to the ECS

The ECS can connect to an established network using the RJ45 in the demarcation box (on page 67), or using the cables that are hard-wired through the connection portals on either end of the HP POD 240e NA. The system uses Modbus TCP/IP for communication.

Environmental control system 35

Connecting to the ECS through the demarcation box

To connect the network to the ECS control panel, route an Ethernet cable to the appropriate RJ45 connector inside the HP POD 240e NA demarcation box (on page 67).

Overview

The POD AHU systems are designed to condition the air in a portable, containerized computer room, and are installed directly on top of the HP POD 240e NA. The HP POD 240e NA includes a total of four cradles, each holding 3 Adiabatic units, for a total of 12 Adiabatic units.

The AHU system requires a potable water source and HP highly recommends installing a filter to be sure that water is free of particles. For more information about water requirements, see the HP Performance Optimized

Adiabatic components

Datacenter 240e NA Site Preparation and Requirements Guide.

Each Adiabatic unit is housed in a NEMA 3 rated steel frame cabinet that is rated for outdoor use. The exterior of the cabinet is coated with a durable finish to protect against corrosion. Access panels are located on the front and on the rear of the cabinet for easy access to all of the components. The access panels are safety interlocked with the power disconnect switch to prevent the removal of the panel when the switch is in the ON position. The power disconnect switch must be turned OFF to gain access to the electrical compartment.

Adiabatic media

Each Adiabatic unit contains three Adiabatic media, each with its own solenoid water supply valve. An outside source of water must be provided to saturate the media.

HP recommends potable water as the main water source for the media.

outside air temperature and humidity conditions are within the correct range of the operating envelope, the dampers open automatically when the AHU is powered on.

AHU theory of operation

Damper operation Each Adiabatic unit is equipped with louvered dampers that control the airflow through the unit. To control

the environment inside of the HP POD 240e NA, the dampers work together to humidify dry outside air, as needed.

An external source of water must be provided to saturate the evaporative media. When the HP POD 240e NA begins operation, the supplied water is pumped through the pipes and out of the nozzles from the reservoir to the top of the evaporative media where it passes through spray nozzles onto the top of the evaporative media. The air that is pulled in through the media by the POD fans is now conditioned.

The controller sends an analog output signal to operate the outside air damper (1) by modulating it. Next, the bypass damper (2), the isolation damper (3), and the hot aisle return damper (4) are controlled to optimize the balance of outside air with humidified air in order to maintain the conditions in the IT section. The

AHU system 62

isolation damper (3) is used to isolate the dry side of the Adiabatic unit from the wet side during cold weather operation.

Below freezing damper operation The isolation damper (3) is completely closed, so that sub freezing air cannot get to the wet media. The

bypass damper (2) is completely open, enabling a path for the cold, dry air to enter the IT sections. The outside air damper (1) and hot aisle return damper (4) moderate to maintain a set temperature within the IT sections.

If the humidity within the HP POD 240e NA gets too low, water is added to the media to maintain the low RH humidity parameter, unless the ECS is set to Allow Low RH.

Exhaust fan operation

AHU system 64

The HP POD 240e NA is equipped with 10 exhaust fans that remove heated air from the hot aisle. The exhaust fans feature an integrated monitoring function to protect the motor and electronics against damage from jamming, phase loss, or overheating.

If any of the following failure conditions occur, the motor automatically stops and an alarm is signaled:

• Locked rotor

• Low main supply voltage

• Loss of a phase

• Over-heating of the exhaust fan electronics

• Over-heating of the exhaust fan motor

For more information about the exhaust fan, see the HP Performance Optimized Datacenter 240e NA Maintenance and Service Guide.

Static pressure control

The control of static pressure is used to be sure that the airflow from the cold aisle of the IT sections across the rack and into the hot aisle of the HP POD 240e NA remains constant. The pressure in the hot aisle is controlled to external ambient pressure, and the IT sections are slightly higher than the external ambient pressure.
