• After 5 minutes, if the smoke condition is capable of keeping the detector in alarm, and if the Amherst College Campus Police have not acknowledged the alarm, the building fire evacuation signal shall sound throughout the building and cause the Campus Police dispatch to notify the Amherst Fire Department.

Corridor Smoke Detection
For dormitory and other residential occupancies, the use of a pre-alarm smoke detection system shall be utilized in corridors, only.

• If only 1 detector is activated in the corridor, it should transmit a pre-alarm to the Amherst College Campus Police for their response only.
• If a second corridor dector is activated, a fire alarm (Priority 1) should be transmitted to the Amherst College Dispatch Center and building alarm should sound for evacuation.
• The smoke detectors should be installed in the following fashion:

  A	B	A	B, or
  Zone	Zone	Zone	Zone

Certification of Completion – A document that acknowledges the features of installation, operation (performance), service, and equipment with representation by the property owner, system installer, system supplier, service organization, and the authority having jurisdiction.

Evacuation Signal – Distinctive signal intended to be recognized by the occupants as requiring evacuation of the building.

Fire Alarm Control Unit (Panel) – A system component that receives inputs from automatic and manual fire alarm devices and may supply power to detection devices and transponder(s) or off-premises transmitter(s). The control unit may also provide transfer of power to the notification appliances and transfer of condition to relays or devices connected to the control unit. The fire alarm control unit can be a local fire alarm control unit or master control unit.

Fire Command Station (Fire Command Center) – The principle location where the status of the detection, alarm, communications and control systems is displayed, and from which the system(s) has the capability for manual control.

Heat Detector – A device that detects abnormally high temperature or rate of temperature rise.

Household Fire Warning System – A household fire warning system consists of single or multiple station detectors or a listed control unit with automatic fire detectors or a listed control unit with automatic fire detectors and occupant notification appliances. The household fire warning system serves only one dwelling unit, patient room, hotel room or other single area depending on use group requirements in Massachusetts Building Code.

Initiating Device – A system component that originates transmission of a change of state condition, such as a smoke detector, manual fire alarm box, supervisory switch, etc.

Installation and Design – All systems shall be installed in accordance with the specifications and standard approved by the authority having jurisdiction.

Line-Type Detector – A device in which detection is continuous along a path. Typical examples are rate-of-rise pneumatic tubing detectors, projected beam smoke detectors, and heat-sensitive cable.

Municipal Fire Alarm System – A system of alarm initiating devices, receiving equipment, and connecting circuits (other than a public telephone network) used to transmit alarms from street locations to the public fire service communications center.

Presignal Feature – Where permitted by the authority having jurisdiction, systems shall be permitted to have a feature where initial fire alarm signals will sound only in departments offices, control rooms, fire brigade stations, or other constantly attended central locations and where human action is subsequently required to activate a general alarm, or a feature where the control equipment delays general alarm by more than one minute after the start of the alarm processing. The areas where there is a connection to a remote location, it shall activate upon initial alarm signal.

Primary Power Supply – The primary supply shall have a high degree of reliability, shall have adequate capacity for the intended service, and shall consist of one of the following:

(a) Light and power service arranged in accordance with 1-5.2.8

(b) Engine-driven generator or equivalent arranged in accordance with 1-5.2.10

Positive Alarm Sequence – An automatic series that results in an alarm signal, even if manually delayed for investigation, unless the system is reset.

Secondary Supply Capacity and Sources – The secondary supply shall automatically supply the energy to the system within 30 seconds and without loss of signals, whenever the primary supply is incapable of providing the minimum voltage required for proper operation. The secondary (standby) power supply shall supply energy to the system in the event of total failure of the primary (main) power supply or when the primary voltage drops to a level insufficient to maintain functionality of the control equipment and system components. Under maximum normal load, the secondary supply shall have sufficient capacity to operate a local, central station or proprietary system for 24 hours, or an auxiliary or remote station system for 60 hours; and then, at the end of that period, operate all alarm notification appliances used for evacuation or to direct aid to the location of an emergency for 5 minutes. The secondary power supply for emergency voice/alarm communications service shall be capable of operating the system under maximum normal load for 24 hours and then be capable or operating the system during a fire or other emergency condition for a period of 2 hours. Fifteen minutes of evacuation alarm operation at maximum connected load shall be considered the equivalent of 2 hours of emergency operation.
The secondary supply shall consist of one of the following:

(a) A storage battery arranged in accordance with 1-5.2.9

(b) An automatic starting engine-driven generators arranged in accordance with 1-5.2.10 and storage batteries with 4 hours capacity arranged in accordance with 1-5.2.9

(c) Multiple engine-driven generators, one of which is arranged for automatic starting, arranged in accordance with 1-5.2.10, capable of supplying the energy required herein with the largest generator out of service. It shall be permitted for the second generator to be pushbutton start.
Operation on secondary power shall not affect the required performance of a fire alarm system. The system shall produce the same alarm, supervisory, and trouble signals and indications (excluding the ac power indicator) when operating from the standby power source as produced when the unit is operating from the primary power source. Separate Sleeping Area – The area or areas of the family living unit in which the bedrooms (or sleeping rooms) are located. For the purpose of this guide, bedrooms (or sleeping rooms) separated by other use area, such as kitchens or livings rooms (but not bathrooms), shall be considered as separate sleeping areas.

Shapes of Ceilings – Those shapes of ceilings are classified as follows:

Sloping Ceilings – Those having a slope of more than 1 ½ in. per ft. Sloping ceilings are further classified as follows:

(a) Sloping-Peaked Type – Those in which the ceiling slopes in two directions from the highest point. Curved or domed ceilings may be considered peaked with the slope figured as the slope of the cord from highest to lowest point.

(b) Sloping-Shed Type – Those in which the high point is at one side with the slope extending toward the opposite side.

Smooth Ceiling – A surface uninterrupted by continuous projections, such as solid joists, beams, or ducts, extending more then 4 in. below the ceiling surface. Single Station Alarm Device – An assembly incorporating the detector, control equipment, and the alarm-sounding device in one unit operated from a power supply either in the unit or obtained at the point of installation.

Smoke Detectors – A device that detects visible or invisible particles of combustion.

Zone – A defined area within the protected premises. A zone may define an area from which a signal can be received, an area to which a signal can be sent, or an area in which a form of control can be executed.
