VESDA air sampling smoke detection system

CAUTION: Excess dust within the HP POD 20c can cause the VESDA smoke detector to trigger

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 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 then the VESDA system sends an alarm

• 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)

contact local Authorities

The fire system operator panel indicates which initiation sequence has begun with indicator lights and a panel alarm. These signals are also available to the site BMS system, if connected.

After the fire suppression system is activated by a VESDA signal or a manual fire button, a 60-second countdown begins before the fire suppression agent is released to the HP POD 20c interior through the fire suppression system piping.

VESDA initiation The VESDA fire suppression system signal has two levels that the system cycles through when smoke is

detected.

• Level 1—Indicates that the potential for a fire is present. The strobes are illuminated and the horns are

in the Warning stage. A fire has not yet been detected and personnel may investigate to determine if there is a potential for a fire or if a false indication has occurred.

• Level 2—Indicates that fire does exist. VESDA Level 1 has already have been reached, the strobes

illuminate, and the horn progresses to the Pre-discharge stage. A 60-second countdown to fire suppression agent release begins and personnel should evacuate immediately.

Press the fire suppression abort button to interrupt the fire suppression release countdown. Pressing the abort button resets the countdown to 10 seconds, regardless of the amount of time elapsed from the original 60-second countdown. The abort button can be pressed multiple times to reset the fire suppression release

Life safety systems 23

agent countdown to 10 seconds. The fire suppression agent is released when the countdown is exhausted and the horn progresses to the Post-discharge stage.

Personnel can press and hold the fire suppression abort button to stop the original 60-second initiation sequence. When the abort button is released, the system countdown resets to 10 seconds. The fire suppression agent release begins when the 10-second countdown is over and the horn progresses to the Post-discharge stage.

Manual initiation Manual initiation causes the fire strobe lights to illuminate, the horn goes to the Pre-discharge stage, and a

30-second countdown until the fire suppression agent release begins. The agent release is certain at this time and cannot be aborted. After the fire suppression agent is released, the system goes to the Post-discharge stage.

The fire suppression abort button is inactive if a manual fire pull was activated and the release of the fire suppression agent is imminent. All personnel should immediately evacuate.

Emergency egress

The HP POD 20c includes the following features for life safety egress on all access doors:

• Panic bar

• Door strikes

o Standard hardware—Door strikes o Optional hardware—Electric door strikes

Each personnel door includes a standard panic bar to ensure safe exit. The optional egress hardware included in the HP POD 20c (including electric panic bars, electric strikes, and magnetic locks) are tied to the fire alarm to enable uninhibited egress in the event of an emergency.
