Smoke Detector with Transmitter
Models 301/302
Description:
The Models 301/302 are self-contained photoelectric type smoke detectors with an integral
transmitter. The model 301 has a sounder and the model 302 does not. The detectors
comply with UL 268 and are designed to provide open area protection. The transmitter is
fully supervised for tamper, low battery, chamber sensitivity and RF signal integrity. The
internal sounder in the model 301 can also be turned on remotely by the FACP. The smoke
detector is powered by a single 3 volt lithium battery as listed under the specifications
section of this manual and the label on the product. The Models 301/302 are intended to be
used with CWSI Fire Alarm Control Panels. Refer to the FACP manual for compatibility
details.
IMPORTANT: Smoke detectors must be tested and maintained regularly following NFPA
72 requirements. At a minimum, cleaning should be performed annually.
Programming:
The 301/302 must be enrolled into the FACP before installing the device. The Model
301/302 will not report Alarms, Supervisory or trouble signals unless it is enrolled
into the control panel. The smoke detector can be enrolled at the control panel or any
enrolled repeater. Place the FACP in enrollment mode then install the battery in the smoke
detector observing polarity. The model 301/302 serial number will be displayed on the
FACP. Refer to the control panel installation instructions for further details on enrollment
and transmitter programming options. After the model 301/302 is enrolled, remove the
battery and reinstall it only at the transmitters intended mounting location.
Installation:
Select an accessible location that is not prone to tampering or accidental damage. The
Model 301/302 must be installed and maintained in accordance with the National Fire
Protection Association’s Standards (NFPA), the National Electrical Code and all local
fire and electrical requirements. The mounting surface should be relatively flat and
capable of accepting screws or anchors. The smoke detector is to be installed in an indoor
dry location. Exposure to weather or corrosive conditions may damage the unit. Smoke
detectors are not to be used with detector guards unless the combination has been
evaluated and found suitable for that purpose. Perform the signal test described in this
manual prior to and after permanently mounting the unit. Note: If the detector is
mounted to a removable ceiling tile, the tile must be secured with the appropriate fasteners
to prevent tile removal or mount the detector across a ceiling panel support as shown in
figure 1. First install the mounting bracket using the screws supplied. Install the battery in
the battery holder. The polarity is marked on the holder. Attach the detector to the bracket
by turning the detector in a clockwise direction until it clicks into place. Wait for the green
and red LED’s to indicate standby condition (green blinks every 10s and red off) then
perform the signal test and fully test the unit for alarm as described in Alarm Testing.

Figure 1 Proper Mounting to Ceiling Tile
Tamper-Resistant Feature
The smoke detector includes a tamper-resistant feature that prevents removal from the
mounting base without the use of a tool. To engage the tamper-resistant feature, cut the
small plastic tab located on the mounting base (Figure 2), and then install the detector. To
remove the detector from the base once it has been made tamper resistant, use a small
screwdriver to depress the square tamper release tab, located on the skirt of the mounting
base, and turn the detector counterclockwise.
Figure 2 Tamper Resistant Feature
Cautions:
1. Make sure the battery is firmly installed in the smoke detector battery compartment.
2. The unit must be secured tightly to the wall, so as to not be dislodged.
3. Test the unit after any service, battery change or as often as local or national codes
dictate.
Do NOT Install Detectors in the Following Areas:
In or near areas where particles of combustion are normally present such as
kitchens; in garages; near furnaces, hot water heaters, or gas space heaters.
In very cold or very hot areas.
In wet or excessively humid areas, or next to bathrooms with showers.
In dusty, dirty, or insect-infested areas.
Near fresh air inlets or returns or excessively drafty areas.
Consult NFPA 72, the local Authority Having Jurisdiction (AHJ), and/or applicable codes for
specific information regarding the spacing and placement of smoke detectors. Refer to
technical bulletin part number CWSI-IM-300-TB-Rev C for more information.

Alarm Operation:
When the detector senses smoke the Green LED extinguishes, the Red LED turns on
steady, the internal sounder* turns on in the temporal pattern and the following occurs:
1. An initial alarm signal is transmitted.
2. A 60 second delay occurs. If during this delay the alarm condition is reset, a restore
signal is sent ending the alarm cycle.
3. The continued alarm condition causes a repeat alarm transmission.
*Except on the model 302.
4. Another 60 second delay as in step 2 occurs.
5. Step 4 repeats at 60 second intervals until reset.
Tandem Sounder Feature Model 301 only
The model 301 can be installed in living and common areas however when used in
common areas do not program the tandem feature. The model 301 allows the smoke
detectors piezo sounder to be turned on or off in tandem with an RF command signal from
the FACP. This enables an installation to be programmed so that when an alarm is
received from any smoke detector sensing smoke the FACP can activate the sounder in
one or more smoke detectors that have not sensed smoke. When activated, the sounder

will turn on in the temporal pattern. Note: Only the smoke detector sensing smoke will
transmit an alarm signal. This feature must be programmed into the FACP to function.
Refer to the FACP manual for additional information and programming instruction. If the
detector is in alarm due to smoke detection the tandem silence signal from the control
panel will not silence the sounder. If the detector is in alarm due to smoke detection and it
receives the tandem on signal the sounder will remain active even if smoke clears from the
chamber. A tandem silence signal will be required to turn off the sounder.
Alarm Testing
Detectors must be tested after installation and following maintenance or battery
replacement. NOTE: Before testing, notify the proper authorities that maintenance is
being performed and the system will be temporarily out of service. Place the FACP in
test to prevent any unwanted alarms. Perform both A and B below to properly test the
301/302 detector. If a detector fails any of the tests below, it should be cleaned as outlined
in the Maintenance section. If the detector still fails, it should be replaced.
A. Test Switch
Note: This test will only function if the detector is operating within its proper sensitivity limits
and is not in a low battery condition.
The purpose of this test is to check the functionality of the circuitry. It will not cause an
alarm signal to be transmitted.
1. An opening for the recessed test switch is located on the detector housing. (Figure 3)
push and hold for 5 seconds then release.
3. If the detector is within the listed sensitivity limits, the following will occur:
a. The green LED turns off.
b. The red LED turns on steady.
c. The sounder activates with the temporal pattern.*
4. Perform step B below.
B. Smoke Entry Test
Note: This test will cause an alarm signal to be transmitted. Wait at least two minutes after
power up before performing this test.
1. Hold a smoldering punk stick or cotton wick at the side of the detector and gently blow
smoke through the detector until the unit alarms. Canned aerosol is also an acceptable
method
2. Verify the alarm signal was received at the control panel.
*Except on the model 302
3. If both test A+B pass, remove the panel from test mode and notify the proper authorities
when the system is back in service.
Sensitivity Testing
Note: Wait at least two minutes after power up before performing the sensitivity test.
To measure the detector sensitivity use System Sensor model SENS-RDR Infrared
Sensitivity Reader tool. Refer to the instruction manual of the model SENS-RDR (D100-98-
00) for proper use.

Figure 3 LEDS, Sounder, Test Switch and Signal Test Locations
Signal Test:
The test must be performed while the smoke detector is held in its intended mounting
location. Install a battery in the smoke detector. Initiate the test by placing a strong magnet
on the smoke detector housing at the location shown in figure 3. The model 301/302 piezo
sounder will beep once. A delay of up to 15 seconds will occur followed by either one or
two beeps. One beep indicates an unacceptable location and two beeps indicate an
acceptable location. If only one beep is heard then relocate the model 301/302 mounting
position closer to the nearest repeater or control panel and perform the test again. Continue
this procedure until 2 beeps are achieved. Do not mount the smoke detector unless 2
beeps are heard when performing 5 consecutive signal tests. This test must be performed
before and after transmitter installation. Note: A CWSI model AR-3(A), AR-5 repeater or
CWSI FACP must be powered up, installed and enrolled before running this test.
Test Switch Functions:
This switch has multiple functions and is located in an opening on the detector housing as
shown in figure 3. To activate the switch insert a small screwdriver or allen wrench
switch will not cause an alarm at the control panel.
The functions of the Test Switch are:
1. Test the functionality of the detectors circuitry when pressed while the detector is in
standby.
2. Silence the low battery chirp for 12 hours if pressed during low battery.
3. Silence the detector sounder for 5 minutes if pressed anytime while the sounder is
turned on in the temporal pattern.
Low battery:
The model 301/302 smoke detector tests for a low battery condition once every 65 minutes.
The battery voltage has to be at or below 2.7V nominally for two consecutive low battery
tests before a low battery trouble condition is transmitted. When a low battery is detected
the green LED will turn off, the red LED will blink every 45 seconds and a low battery
trouble signal will be transmitted and repeated every 90 seconds. Once the low battery
condition is present for 2 days, the piezo sounder will begin to chirp once every 45
seconds*. This gives the service person time to replace the battery prior to audible
notification. The low battery trouble signal will be transmitted and the piezo sounder will
chirp for an additional 7 days. Pressing the smoke detector test button will silence the
sounder chirp for 12 hours however the low battery trouble signal will continue to be
transmitted every 90 seconds. Where more than one type of trouble exists, all will be

repeated in increments of 90 seconds. Always replace the battery with a new one. Refer to
the Battery Installation and Replacement section for instructions on battery replacement.
*Except model 302
Battery Installation and Replacement:
Warning: Always install a new battery of one of the approved types as listed in the
Specifications section of this manual and the product label. When a battery is first
inserted, a low battery test is performed. If the battery passes the test, the LED’s should
indicate normal standby. If the battery does not pass this test, the unit gives no indication of
operation and the LEDs do not blink at all and a fresh battery should be installed.
To replace the battery:
1. Place the FACP in Test mode to prevent any unwanted alarms.
2. Remove the detector from its mounting base by twisting the detector counterclockwise.
Remove the battery and dispose of properly. If the Tamper Resistant feature was
implemented during installation then follow the instructions under that section for removing
the detector.
3. To insure proper power down sequence, wait a minimum of 20 seconds before installing
a new battery.
4. Install a new approved 3 volt lithium battery in the battery compartment following the
polarity diagram inside the compartment. A power up reset trouble signal should be
indicated on the FACP upon installation of the new battery. A tamper trouble will also be
indicated on the FACP if the smoke alarm is not attached to the base.
5. Reinstall the smoke detector onto the mounting base by turning the detector clockwise.
6. The LED’s should indicate Power up and then Normal Standby conditions as shown in
the LED status and sounder table.
7. Test the detector for alarm operation s described in the Alarm Testing section of this
manual.
8. If the detector does not function as described in items 6+7 then start over at step 2. If it
still doesn’t operate correctly then replace the entire unit.
9. Remove the panel from test mode.
Tamper:
The Models 301/302 contain a built in contact that will cause a tamper signal to be
transmitted if the detector is removed from its mounting position. Upon detector removal, a
tamper signal is transmitted and repeated every 90 seconds until the detector is mounted
on its base. Where more than one type of trouble exists, all will be repeated in increments
of 90 seconds. Note: This trouble is self-restoring on CP-3500D and newer FACP’s.
Power Up Reset:
The Models 301/302 will report this trouble when first powered up. This is normal. If a
power up reset occurs anytime after the initial indication then the transmitter is
malfunctioning. Replace the unit.
Test Failure:
The Models 301/302 transmit a periodic test signal. This trouble condition will be displayed
within 200 seconds on the FACP if it does not receive the test transmission. The detector
may be out of reception range of a repeater or FACP or the detector may have an internal
problem. Perform the signal test described in this manual to determine if there is a
reception problem. Note: This trouble is self-restoring on CP-3500D and newer FACP’s.

Hardware Flt:
The Models 301/302 monitor the integrity of the communications between the smoke
detector board and the RF transmitter board internal to the smoke detector. A Hardware Flt
trouble will be displayed on the FACP if there is a failure with communications between the
two boards. If this occurs replace the smoke detector.
Maintenance / Fault:
The Models 301/302 contain circuitry that allows the detector to automatically adjust its
sensitivity back to the factory setting when it becomes more sensitive due to contaminants
settling in its chamber. If the sensitivity has shifted outside the listed limits the Green LED
will extinguish, the Red LED will flash every 5 seconds and a maintenance required signal
will be sent and repeated every 90 seconds until the condition is corrected. Perform
maintenance on the detector as described in this manual. If the problem persists, replace
the detector.
Figure 4 Removing Screen/Sensing Chamber
Maintenance
Perform maintenance yearly or whenever a Maintenance Req. Trouble signal is indicated.
Warning: Never remove the tamper proof screws attaching the detector cover to the
