Scope of Work/Materials
13850 (28 31 00) - 15
Bid No.041818-Installation of New Fire Alarm System at Adams Elementary School
1.
The detector shall be comprised of four sensing elements, including a photoelectric (light-
scattering) particulate sensor, an electrochemical carbon monoxide (CO) sensor, a
daylight-filtered infrared sensor and solid state thermal sensor(s) rated at 135°F (57.2°C).
The device shall be able to indicate distinct smoke and heat alarms.
2.
The intelligent multi-criteria detection device shall include the ability to combine the
signal of the photoelectric signal with other sensing elements in an effort to react quickly in
the event of a fire situation. It shall also include the inherent ability to distinguish between
a fire condition and a nuisance alarm condition. The product design shall be capable of
selecting the appropriate sensitivity levels based on the environment type chosen by user
in which it is installed (office, manufacturing, kitchen etc.) and then have the ability to
automatically change the setting as the environment changes.
3.
The detector shall indicate CO trouble conditions including 6 months of sensor life
remaining and sensor life has expired. The detector shall indicate a combined signal for
any of the following: low chamber trouble, thermistor trouble, CO self-test failure, IR self-
test failure, and freeze warning.
4.
The detectors shall provide a test means whereby they will simulate an alarm condition
and report that condition to the control panel. Such a test may be initiated at the detector
itself (by activating a switch) or initiated remotely on command from the control panel.
There are three test methods: functional magnet, smoke entry aerosol, or direct heat
method.
I. Intelligent Fire/Carbon Monoxide Detectors (MCS-COF):
1.
The detector shall be comprised of four sensing elements, including a photoelectric (light-
scattering) particulate sensor, an electrochemical CO sensor, a daylight-filtered infrared
(IR) sensor and solid state thermal sensor(s) rated at 135°F (57.2°C). The device shall be
able to indicate distinct smoke and heat alarms.
2.
The advanced multi-criteria detection device shall include the ability to combine the signal
of the photoelectric signal with other sensing elements in order to react quickly in the
event of a fire situation. It shall also include the inherent ability to distinguish between a
fire condition and a nuisance alarm condition. The detector shall be capable of selecting
the appropriate sensitivity levels based on the environment type (office, manufacturing,
kitchen, etc.) in which it is installed, and then have the ability to automatically change the
setting as the environment changes.
3.
The CO detector component shall be capable of a functional gas test using a canned test
agent to test the functionality of the CO sensing cell.
4.
The detector shall indicate CO trouble conditions, including six months of sensor life
remaining and sensor life has expired. The detector shall indicate a combined signal for
any of the following: low chamber trouble, thermistor trouble, CO self-test failure, IR self-
test failure, and freeze warning
5.
The MCS-COF Photo/CO Detector shall be used with the B200S Intelligent Sounder Base.
J. Intelligent Sounder Base (B200S):
1. The B200S sounder base “listens in” to the SLC communication between the attached
sensor head and the fire alarm control panel (FACP) to adopt the same address as the
detector, but as a unique device type on the loop. The FACP can then be programmed to
use that address to command an individual sounder or a group of sounders to activate.
The command set from the panel can be programmed to the specific event, allowing
selection of volume, tone, and group. In addition, the FACPs will enable custom tone
patterns.
