The F220 Photoelectric Smoke Detectors are UL
Listed, open-area photoelectric smoke detectors. Use
them with commercial fire protective signaling
systems and household fire warning systems (see
NFPA 72, the National Fire Alarm Code). These smoke
detectors scatter light using a pulsed infrared source
operating with a gated, high-speed, photodiode
infrared sensor. The symmetry of the optical chamber
allows 360° uniform smoke entry, but minimizes
external light entry. The detectors use low current
electronic circuitry, so they can connect to 12 VDC
nominal or 24 VDC nominal power source circuits.
Functions
Compatible Bases
Configure the detectors into two-wire or four-wire
versions by selecting the appropriate mounting base.
These detectors are compatible with any of the
F220‑B6 bases:
•
F220-B6 12/24 VDC Two‑wire Mounting Base
• F220-B6R Standard 12/24 VDC Four‑wire Mounting
Base
• F220-B6RS 24 VDC Four‑wire Mounting Base with
Sounder
• F220-B6C 12/24 VDC Four‑wire Mounting Base with
Auxiliary Relay
• F220-B6E 12/24 VDC Four‑wire Power Supervision
Mounting Base
•
F220-B6PM 24 VDC Four‑wire Addressable Master
Base
• F220-B6PS 12/24 VDC Four‑wire Addressable Base
Monitoring the Detection Chamber
These detectors have several features that work
together to maximize the performance of the optical
chamber:
• Compensation: The detector monitors the chamber
for the effects of dust build-up within the chamber
and automatically compensates for these effects. If
the chamber becomes contaminated beyond its
ability to compensate, the green LED flashes every
4 sec to indicate trouble.
• Chamber Check Self-diagnostics: The detector
automatically indicates visually if the calibration is out
of the factory-listed range. This meets NFPA
guidelines for sensitivity testing, because you can
visually inspect the detector and check the flash rate
of the LED. If the calibration is out of range, the green
LED on the detector flashes once every 4 sec. This
indicates that the detector must be cleaned following
the instructions provided with the detector.
