Bid No.041818-Installation of New Fire Alarm System at Adams Elementary School
2.5
SUPPLEMENTAL NOTIFICATION APPLIANCE CIRCUIT (HPFF8)
A.
Supplemental Notification Appliance Circuit (HPFF) shall be Model HPFF8 offering
up to 8.0 amps (8.0 amps continuous) of regulated 24-volt power. HPFF shall include the
following features:
1.
Integral Charger: Charge up to 18.0 amp-hour batteries and support 60-hour standby.
2.
2 Input Triggers. Input trigger shall be Notification Appliance Circuit (from fire alarm
control panel) or relay.
3.
Surface-mount back box.
4.
Ability to delay AC fail delay in accordance with applicable NFPA requirements.
5.
Power limited circuitry in accordance with applicable UL standards.
6.
Operates as sync follower or a sync generator.
2.6
SYSTEM PERIPHERALS - SYSTEM SENSOR Velociti
A.
Addressable Devices
– General:
1.
Provide address-setting means using rotary-decimal switches.
2.
Use simple to install and maintain decade-type (numbered 0 to 15) address switches by
using standard screwdriver to rotate 2 dials on device to set address. Devices which use
binary address set via dipswitch packages, handheld device programmer, or other special
tools for setting device address shall not be acceptable.
3.
Detectors: Analog and addressable. Connect to fire alarm control panel's Signaling Line
Circuits.
4.
Addressable Thermal and Smoke Detectors: Provide 2 status LEDs. Both LEDs shall
flash under normal conditions, indicating detector is operational and in regular
communication with control panel, and both LEDs shall be placed into steady illumination
by control panel, indicating alarm condition has been detected. If required, flashing mode
operation of detector LEDs can be programmed off via fire control panel program.
5.
Fire Alarm Control Panel: Permit detector sensitivity adjustment through field
programming of system. Sensitivity can be automatically adjusted by panel on time-of-day
basis.
6.
Using software, detectors shall automatically compensate for dust accumulation and other
slow environmental changes that may affect their performance. Detectors shall be listed
by UL as meeting calibrated sensitivity test requirements of NFPA 72, Chapter 7.
7.
Detectors shall be ceiling-mounted and shall include separate twist-lock base with tamper-
proof feature.
8.
Following bases and auxiliary functions shall be available:
a.
Standard base with remote LED output.
b.
Sounder base rated at 85 dBA minimum.
c. Intelligent Addressable Sounder base rated at 75 dBA minimum.
d.
Form-C relay base rated 30 VDC, 2.0 A.
e.
Isolator base.
9.
Detectors shall provide test means whereby they will simulate alarm condition and report
that condition to control panel. Such test shall be initiated at detector itself by activating
magnetic switch or initiated remotely on command from control panel.
10. Detectors shall store internal identifying type code that control panel shall use to identify
type of device (ION, PHOTO, THERMAL).
