Bid No.041818-Installation of New Fire Alarm System at Adams Elementary School
B.
Addressable Manual Stations (MS-7AF):
1.
Manual Fire Alarm Stations: Non-code, non-break glass type, equipped with key lock so
they may be tested without operating handle.
2.
Operated Station: Visually apparent, as operated, at a minimum distance of 100 feet (30.5
m) from front or side.
3.
Stations shall be designed so after actual activation, they cannot be restored to normal
except by key reset.
4.
Manual stations shall be constructed of Lexan with clearly visible operating instructions
provided on cover. The word FIRE shall appear on front of stations in raised letters, 1.75
inches (44 mm) or larger.
5.
Addressable manual stations shall, on command from control panel, send data to panel
representing state of manual switch and addressable communication module status.
C.
Intelligent Thermal Detectors (ATD-RL2F): Intelligent addressable devices rated at 135 degrees
F (58 degrees C) and have rate-of-rise element rated at 15 degrees F (9.4 degrees C) per
minute. Connect via 2 wires to fire alarm control panel signaling line circuit.
D.
Intelligent Photoelectric Smoke Detectors (ASD-PL2F): Use photoelectric (light-scattering)
principal to measure smoke density and shall, on command from control panel, send data to
panel representing analog level of smoke density.
E.
Intelligent Ionization Smoke Detectors (ASD-IL2F): Use dual-chamber ionization principal to
measure products of combustion and shall, on command from control panel, send data to panel
representing analog level of products of combustion.
F.
Intelligent Multi-Criteria Acclimating Detectors (MCS-ACCLIMATE2F):
1.
Addressable device designed to monitor a minimum of photoelectric and thermal
technologies in single-sensing device. Include ability to adapt to its environment by
utilizing built-in microprocessor to determine its environment and choose appropriate
sensing settings. Allow wide sensitivity window, with no less than 1 to 4 percent per foot
obscuration. Utilize advanced electronics that react to slow smoldering fires and thermal
properties within single sensing device.
2.
Microprocessor: Capable of selecting appropriate sensitivity levels based on environment
type it is in, such as office, manufacturing, or kitchen, and then have ability to
automatically change setting as environment changes, as when walls are moved or as
occupancy changes.
3.
Intelligent multi-criteria detection device shall include ability to combine signal of thermal
sensor with signal of photoelectric signal to react hastily in event of fire situation. Include
inherent ability to distinguish between fire condition and false alarm condition by
examining characteristics of thermal and smoke sensing chambers and comparing them to
database of actual fire and deceptive phenomena.
G.
Intelligent Laser Detectors (ASD-LS): Sensor device designed to use laser diode similar to way
photoelectric sensor uses LEDs inside of sensing chamber. Detector design shall allow wide
sensitivity window, with no less than 0.2 to 4 percent per foot obscuration. Detector shall be
used as indicated in special application clean-room-type environments only.
