Gym and Classroom Replacement N10.024.00
New Orleans, Louisiana July 20, 2012
FIRE DETECTION SYSTEM 16600 -7
2. Speakers shall include field selectable power taps from 1/8 watt to 8 watts with listed
sound output up to 96 dBA for speakers and 93 dBA for speaker strobes. All models
shall have provisions for standard reverse polarity type supervision for strobe portion and
IN/OUT field wiring using terminals that accept #12 to #18 AWG wiring. The speaker
shall incorporate sealed back construction.
3. Faceplate shall be white.
D. Addressable Devices (General)
1. Addressable devices shall provide an address-setting means using rotary decimal switches.
Addressable devices shall use simple to install and maintain decade (numbered 1 to 10)
type address switches.
2. Addressable smoke and thermal detectors shall provide dual alarm and power LEDs.
Both LEDs shall flash under normal conditions, indicating that the detector is operational
and in regular communication with the control panel, and both LEDs shall be placed into
steady illumination by the control panel, indicating that an alarm condition has been
detected. The flashing of the detector LEDs shall be optional through the system field
program. An output connection shall also be provided in the detector base to connect an
external remote alarm LED.
E. Addressable Detectors
1. Smoke detector sensitivity shall be set through the control panel and shall be adjustable in
the field through the field programming of the system. Sensitivity may be automatically
adjusted by the panel on a time-of-day basis.
2. Using software in the control panel, detectors shall automatically compensate for dust
accumulation and other slow environmental changes that may affect their performance.
The detectors shall be listed by UL as meeting the calibrated sensitivity test requirements
of NFPA Standard 72, Chapter 7. Detectors shall be ceiling-mounted and shall include a
separate twist-lock base with tamper proof feature.
3. 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 magnetic switch) or initiated remotely on command from the
control panel.
4. Detectors shall also store an internal identifying type code that the control panel shall use
to identify the type of device (ION, PHOTO, THERMAL).
5. Photoelectric detectors shall use the photoelectric (light-scattering) principal to measure
smoke density and shall, on command from the control panel, send data to the panel
representing the analog level of smoke density.
6. Thermal detectors shall be intelligent addressable devices rated at 135°Fahrenheit
(58°Celsius) and have a rate-of-rise element rated at 15°Fahrenheit (9.4°Celsius) per
minute. The detectors shall use an electronic sensor to measure thermal conditions
caused by a fire and shall, on command from the control panel, send data to the panel
representing the analog level of such thermal measurements.
F. Addressable Pull Stations
1. Addressable pull boxes shall, on command from the control panel, send data to the panel
representing the state of the manual switch. They shall use a key operated test-reset lock,
and shall be designed so that after actual emergency operation, they cannot be restored to
normal use except by the use of a key.
