Combination Photoelectric Smoke
and Carbon Monoxide Alarm
120VAC/9VDC Single/Multiple Station Smoke
and CO Alarm
Product Listings
Applications
The GN-503 (120VAC/9VDC) Series of combination photoelectric smoke and
electrochemical sensor carbon monoxide alarms are for use as an evacuation device in
all dwelling units, including but not limited to homes, apartments, hospitals, hotels, mo-
tels and other commercial occupancies. The GN-503 Series is listed in compliance with
ANSI/UL 217, ANSI/UL 2034, for installation per NFPA 720 and NFPA 72.
Available in two models, the GN-503 Series is engineered to virtually eliminate
nuisance alarms and deliver outstanding performance wherever reliable smoke and CO
protection is required.
The GN-503 Series is provided with a 9VDC alkaline battery for electrical back-up in
the event building power is lost. The battery impedance is verified and the alarm pro-
vides a low or missing battery warning. The battery drawer provides easy replacement
without removing the unit from the wall or ceiling.
The Gentex GN-503 Series is provided with a self test and functionality test feature.
The self test notifies if the smoke/CO alarm is functioning properly or needs attention.
The functionality tests that the smoke/CO alarm is operating properly. The self and
functionality tests are in compliance with NFPA 72 and ANSI/UL Standards.
Features of the combination alarm series include DUALINK
®
tandem
capabilities with all Gentex tandem interconnect capable smoke
alarms, CO alarms and combination smoke/CO alarm products.
Options include a Form A/Form C dry contacts (GN-503F) for remote annunciation
and connection to a protected premises alarm system to provide a supervisory/trouble
signal. The GN- 503 provides temporal 3 evacuation tone for smoke alarm and all units
provide temporal 4 tone for CO alarm annunciation. The temporal 3 evacuation tone for
smoke alarm will take precedence of the temporal 4 tone for CO alarm.
