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 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 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 indicating that a fire might exist.

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