VESDA air sampling smoke detection system

CAUTION: Excess dust within the HP POD 20c 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 red VESDA piping that runs throughout the HP POD 20c includes inlets for smoke sampling. The VESDA uses a high-efficiency aspirator to continuously draw in air from the HP POD 20c and circulate the air through

adual-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 then the VESDA system sends an alarm signal indicating that a fire might exist.

•Level 2—Smoke concentration reaches the second setpoint, and then the VESDA system indicates that a fire does exist in the HP POD 20c and sends an alarm signal and 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 button (on page 21)

•Fire alarm indicators (on page 22)

•Fire suppression system (on page 22)

Manual fire button

The HP POD 20c includes two fire buttons. One fire button is located next to the personnel access door and the second fire button is located in the fire suppression bump out.

Manually activating a fire button does the following:

•Activates the POD fire alarm system horn and strobe lights
