NovaTM 30 Wireless Supervised
Photoelectric Smoke Detector
Installation Instructions

GENERAL DESCRIPTION

Nova 30 is a battery-powered photoelectric smoke
detector with a built-in supervised wireless transmitter.
When sufficient smoke is detected or the test feature is
operated, the detector will sound its alarm horn and the
transmitter will send an ALARM message. If the alarm
condition remains, the message will be repeated 2 or
more times (with 65 second intervals). The Alarm
output in the receiver will remain activated until the
alarm condition is cleared.

The smoke alarm provides the following features:

Smoke Alarm/base lock discourages unauthorized

removal of the smoke alarm by requiring a screwdriver
to remove the alarm from the base.

CleanMe™ Self-diagnostics monitors its own
sensitivity and operational status. If the smoke alarms
drifts out of the sensitivity range or fails internal
diagnostics, it extinguishes its LED

Internal Signal Outputs

The smoke alarm provides the following signals for
interfacing:

• Alarm

• Alarm restore

• Low battery

• Maintenance alert (Visible only)

Selecting a Location

Selecting a suitable location is critical to the operation of
smoke alarms. This equipment should be installed in
accordance with the National Fire Protection Association’s
(NFPA) Standard 72. See Figure 2.

A-8-1.2.1.C Are More Smoke Alarms Desirable?

The required number of smoke alarms might not provide
reliable early warning protection for those areas separated
by a door from the areas protected by the required smoke
alarms. For this reason, it is recommended that the
householder consider the use of additional smoke alarms
for those areas for increased protection. The additional
areas include the basement, bedrooms, dining
room, furnace room, utility room, and hallways not
protected by the required smoke alarms. The installation of
smoke alarms in kitchens, attics (finished or unfinished), or
garages is not normally recommended, as these locations
occasionally experience conditions that can result in
improper operation.

Important: Regulations pertaining to smoke alarm
installations vary from state to state. For more information,
contact your local fire department or local authority having
jurisdiction.

In addition to NFPA 72, use the following location
guidelines to optimize performance and reduce the
chance of false alarms from the alarm:

• Locate ceiling-mounted smoke alarms in the center
of a room or hallway at least 4 inches from any

walls or partitions.

• Locate wall-mounted smoke alarms so the top of

the alarm is 4 to 12 inches below the ceiling.

• Locate in a suitable environment as follows:

− Temperature between 40ºF (4.4ºC) and 100ºF

(37.8ºC))

− Humidity between 0 and 95% non-

condensing

• Locate away from air conditioners, heating

registers and any other ventilation source that may
interfere with smoke entering the alarm.

• Mount smoke alarms on a firm permanent surface.

• Locate away from large metallic objects when listed

with a transmitter.

Installing the Alarm

1. If you are using the alarm/base lock, remove the

two knockouts on the mounting base. See Figure 3.

2. Slide the battery compartment cover away from the

alarm to unsnap it and lift it off. See Figure 4.

3. Follow the write mode procedure as described in

the receiver installation of the operational manual.

4. Observing proper polarity, insert two 3V lithium

batteries into the alarm battery compartment and
replace the battery compartment cover.

5. Write message will be sent automatically
10 seconds after installing the batteries.

6. Remove the red plastic dust cover from the alarm.

The alarm is shipped with a dust cover for
protection on construction sites with dusty
environments.

7. Using the two screws and anchors provided,

mount the base

8. Attach the alarm to the mounting base as follows:

− Line up the raised tab on the lip of the alarm

with the slot on lip of the mounting base. See
figure. 4

− Insert the smoke alarm into the base and

turn clockwise approximately 15 degrees. It
should snap firmly into place.

Important: the alarm cannot be attached to the
mounting base if no batteries are installed.

9. Test the alarm (see Smoke Testing the Alarm).

Smoke Testing the Smoke Alarm

Smoke alarms should be tested in place annually using
smoke or canned aerosol simulated smoke. Follow the

disconnect the batteries for 30 seconds and then
reconnect them.

instructions on the canned smoke or use the following
steps to test the alarm with smoke:

1. Hold a smoldering punk or cotton wick close to

the smoke entry openings.

2. Gently direct the smoke into the alarm for 20

seconds or until an alarm is indicated.

BE SURE TO PROPERLY EXTINGUISH THE
SMOKE SOURCE AFTER TESTING! The alarm
LED should remain on and the alarm will sound a
temporal rhythm until the Test/Silence button is
pressed. The alarm automatically resets when smoke is
no longer present.

Understanding the Test/Silence
Button

The Test/Silence button on the alarm performs three
functions as follows:

Testing = Press the Test/Silence button for 2 seconds.
The alarm performs a sounder test and a sensitivity
test.

Silence alarm = Press to silence the sounder during
an alarm. After a few minutes, the sounder and alarm
resume if smoke is still present.

Silence trouble chirp = Press to silence a trouble
chirp. The trouble chirp resumes after 24 hours if the
trouble condition is not corrected.

Testing the Alarm Sensitivity

The smoke alarm provides a sensitivity level test mode that allows you to check the smoke alarms sensitivity using the
Test/Silence button and the LED indicator on the alarm as follows:

1. Press the Test/Silence button on the smoke alarm for 2 seconds. Once the test starts, the alarm LED flashes one to

nine times.

2. Count the number of times the LED flashes and use the following table to determine the status of the smoke

sensitivity and what action to take, if any.

Flashes Obscuration

8, 9 N/A Detector is too sensitive. Verify that the smoke chambers is snapped down securely.

After the flashes, if the sensitivity is within limits and all other tests pass, the alarm goes into alarm and resets
after 3 seconds.

If the sensitivity is not within limits, or an unserviceable hardware fault has been detected, the smoke alarm LED

extinguishes until the alarm is serviced.

Clean the unit and replace the smoke chamber.

Attaching and Removing the Smoke Alarm

To remove the smoke alarm from the mounting base,

grasp the alarm and turn it counterclockwise approximately
15 degrees. The smoke alarm should snap off of the mounting
base.

To remove the alarm from the mounting base when the

alarm/base lock is used, insert a small screwdriver into the

locking tab slot on the side of the base and press in while
simultaneously turning the alarm counterclockwise 15
degrees. See Figure 5.

Attach the smoke alarm to its mounting base as follows:

− Line up the raised tab on the lip of the smoke alarm

with slot on the lip of the mounting base. See Figure 4.

− Insert the smoke alarm into the base and turn

clockwise approximately 15 degrees. It should snap

firmly into place.

Understanding the LED

The LED on the alarm indicates the status of the
alarm as follows:

FLASHING = Flashes every 9 seconds to indicate
normal operation.
ON = Detects smoke.

OFF = Trouble or maintenance is required.

When to Replace the Batteries

The Nova 30 smoke alarm requires two 3V lithium A
batteries as listed on the battery compartment cover.
The required batteries are available where other
batteries are sold.

Battery life is a minimum of 1 year and varies
depending on how often the alarm is tested. When the
batteries are low, the alarm extinguishes its LED and
chirps every 30 seconds until the batteries are
replaced. The sounder can be silenced for 24 hours by
pushing the Test/Silence button.
