Description
The 9120 Series of photoelectric smoke alarms is
designed for residential applications, including homes,
apartments, hospitals, hotels and offices, in compliance
with UL 217, applicable UBC/UFC Standards and NFPA
74 / NFPA 72, Chapter 2. Available in many different
models, the 9120 Series is engineered to virtually
eliminate nuisance alarms and deliver outstanding
performance wherever reliable fire protection is
required.
The 9120 Series is provided with a 9 VDC alkaline
battery for back-up in the event building power is lost.
The battery impedence is verified and the detector
provides a low or missing battery warning. The 9120
Series provides an exclusive patented three position
test feature that simulates a 0.85% and 3.5% actual
smoke condition in full compliance with NFPA 74/NFPA
72, Chapter 2 and UL Standards.
Options include self-restoring 135°F integral or isolated
thermals, and Form A/Form C dry contacts for remote
annunciation. Tandem interconnection of up to 12 units
is available on several models; tandem interconnection
of up to 6 units is available on “F” models, which
activate the dry contacts from a remote alarm through
the tandem wire or a local alarm.
Engineering Specifications
The Photoelectric Smoke alarm shall be a 9120 Series
or approved equal which shall provide at least the
following features and functions.
1. Nominal sensitivity shall be 2.5%.
2. The alarm shall utilize an infrared LED sensing
circuit which pulses in 4 to 5 second intervals when
subjected to smoke. After 2 consecutive pulses in
smoke, the alarm will activate.
3. The alarm shall have a 9 VDC alkaline batteryas
a back-up in the event building power is lost.
4. The 9 VDC battery impedence shall be verified by
the circuit of the smoke alarm.

UL listed for 30 foot spacing (Refer to NFPA 72
for proper smoke detector placement.)
The alarm shall provide an indicator when the
battery is low in power or high impedence or is
missing.
The alarm shall provide minimum 5-to-1 signal-tonoise ratio in the optics frame to assure stability of
operation in environments of high RF and transient
conditions.
The sensing chamber shall be fully screened to
prevent entrance of small insects, thus reducing
the probability of false alarms.
A solid state piezo alarm rated at 90dBA at 10ft.
A visual LED monitor (condition indicator) will
slow pulse in normal operation and rapid pulse
in alarm.
An easily accessible test knob shall be provided. The test knob in the TEST position will simulate
an actual smoke condition of approximately
3.5% causing the detector to alarm within 20-36
seconds. It will also have the capability of testing
to 0.85% as a required minimum. A magnetic
switch closure or other switch closure, or smoke
generating equipment which does not scatter the
light beam or test sensitivity is not sufficient, as
indicated in National Code.
The detector shall have tandem interconnect
capability of up to 12 units or 6 units with relay.
Unit must be UL 217 listed for both wall and ceiling
mount.
Unit shall also meet all requirements of the State
of California Fire Marshal.
