PART 2 PRODUCTS

2.1 SYSTEM DESIGN

2.1.1 Operation

NOTE: Shutdown of mechanical (HVAC) systems must be carefully coordinated between this section and mechanical sections. All HVAC systems must be shutdown upon operation of the alarm system unless the shutdown of individual HVAC units separately when smoke is detected in each unit's ductwork is approved by the AHJ. Shutdown of all HVAC systems upon any alarm is desirable from a life safety standpoint, but may not be practical in all cases.

To shut down all HVAC units from the fire alarm control panel retain the reference to HVAC equipment shutdown in paragraph titled "Operation" and delete reference to shutdown in paragraph titled "Duct Smoke Detectors". If it is desired to shutdown systems on an individual unit basis, delete the reference to HVAC equipment shutdown in paragraph titled "Operation", and retain the reference to shutdown in paragraph titled "Duct Smoke Detectors".

Provide a complete, electrically supervised, code 3 temporal common coded, annunciated, fire alarm system as described herein, and as shown on the drawings.

2.1.1.1 Fire Alarm Signal Initiation

Operation shall be such that actuation of any:

a. Manual station

b. Heat detector

c. Smoke detector

d. Automatic fire sprinkler system

e. Fire extinguishing system Shall cause all of the following actions:

a. All building evacuation alarm devices (notification appliances) to operate continuously;

b. The annunciator(s) to properly register;

c. A coded signal to be transmitted over the station fire alarm system;

d. Heating, ventilating, and air conditioning equipment to shut down;

e. Electro-magnetic door holders to de-energize.

All operations shall remain in the alarm mode (except alarm notification appliances if manually silenced) until the system is manually restored to normal. A signal should be transmitted to the ECC (Bldg 13730) and the fire alarm shop (Bldg 11439).

2.1.1.2 Supervisory Signal Initiation

NOTE: Include this paragraph when any of the listed supervisory signal initiating devices are provided by the project or exist in the building and edit accordingly, otherwise delete.

Operation of a sprinkler control valve tamper shall not cause an alarm, but shall cause operation of common system audible trouble signal, and display of a visual indication distinct from that displayed to indicate a fire alarm or a fault in the supervisory circuit and transmission of a distinct supervisory signal to the ECC (Bldg 13730) and the fire alarm shop (Bldg 11439).

2.1.1.3 Monitoring Integrity of Installation Conductors

NOTE: "Class A" monitoring should be specified for buildings with high life hazard such as hospitals and high rise buildings, and for strategically critical or extremely high monetary value facilities. For all other facilities "Class B" monitoring should usually be specified. (Comply with the limitations contained in NFPA 72 on the number of initiating devices permitted per circuit for both "Class A" and "Class B" circuits.) For all

"Class A" circuits, specify separate conduit for return conductors. For additions to existing alarm systems, specify the type of monitoring already in use.

All system circuits shall be electrically monitored for integrity including the following:
