Before Installing
Please read thoroughly System Sensor Application Guide: System Smoke De-
tectors, which provides detailed information on detector spacing, placement,
zoning, wiring, and special applications. Copies are available on System Sen-
sor’s web site: www.systemsensor.ca.
NOTICE: This manual shall be left with the owner/user of this equipment.
IMPORTANT: This detector must be tested and maintained regularly follow-
ing CAN/ULC S536. At a minimum, cleaning should be performed annually.
General Description
Models C2WTR-BA and C2WTA-BA are 2-wire photoelectric smoke detectors;
models C4WTR-BA, C4WTA-BA, C4WTAR-BA, and C4WITAR-BA are 4-wire
photoelectric smoke detectors. All models incorporate a state-of-the-art optical
sensing chamber and an advanced microprocessor. The microprocessor 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.
In order for this feature to work properly, the chamber must never be opened
while power is applied to the smoke detector. This includes cleaning, main-
tenance or screen replacement. All models also feature a restorable, built-in,
fixed temperature (135°F / 57 °C) thermal detector and are also capable of
sensing a freeze condition if the temperature is below 41°F (5°C)
Models C2WTA-BA, C4WTA-BA, C4WTAR-BA, and C4WITAR-BA contain a
piezoelectric horn which generates the ANSI S3.41 temporal pattern in an
alarm condition. All detectors on a zone will sound when the power supply to
them is reversed. The CRRS-MODA can be used for the power supply reversal
function. The CRRS-MODA also enables all the detectors’ sounders on a zone
to be synchronized and allows the zone to be silenced from the panel by en-
tering the alarm silence key at the keypad.
The detector that initiated the alarm condition will have its red LED and
Form C relays (if applicable) latched until reset by panel.
The model C4WITAR-BA photoelectronic smoke sensor is isolated from the
fixed-temperature heat sensor, providing a self-resetting, local audible smoke
alarm that does not alarm at the panel. Only the fixed-temperature heat sensor
will cause the C4WITAR-BA to initiate an alarm at the panel and the relay to
change its state.
NOTE: In order for all i3sounder detectors on a loop to sound when the panel
alarms, the supply voltage polarity must be reversed. A reversing relay, System
Sensor model number CRRS-MODA, must be used. The CRRS-MODA is de-
signed to allow all i3Series detectors in the same loop to sound when one of
the detectors goes into alarm. In addition, the CRRS-MODA will synchronize
all of the i3Series sounder smoke detectors on the loop. Some panels may
require the use of programmable outputs. Refer to System Sensor literature for
further information on the CRRS-MODA.
All i3Series detectors are designed to provide open area protection. Two-wire
models must be used with compatible ULC Listed panels only.
When used with an “i3Ready” control panel or the i3Series C2W-MOD2A
module (refer to installation manual), the C2WTR-BA and C2WTA-BA are ca-
pable of generating a “maintenance needed” signal. The C2W-MOD2A can
indicate a need for cleaning, replacement, or a freeze trouble at the control
panel or module.
WARNING
The C2W-MOD2A has replaced the previous model number C2W-MODA. To
ensure proper remote maintenance signaling capabilities, do not use the C2W-
MODA with i3model numbers C2WTR-BA and C2WTA-BA.
Installation of the C2WTR-BA, C2WTA-BA, C4WTR-BA, C4WTA-BA, C4WTAR-
BA, and C4WITAR-BA detectors is simplified by the use of a mounting base
that may be pre-wired to the system, allowing the detector to be easily in-
stalled or removed. The mounting base installation is further simplified by the
incorporation of features compatible with drywall fasteners.
Two LEDs on the detector provide a local visual indication of the detector’s
status:
Table 1: Detector LED Modes
Green LED Red LED
Power-up Blink 10 sec Blink 10 sec
Normal (standby) Blink 5 sec —
Out of sensitivity — Blink 5 sec
Freeqe Trouble — Blink 10 sec
Alarm — Solid
During an initial power-up delay, the red and green LEDs will blink synchronously once
every ten seconds. It will take approximately 80 seconds for the detector to finish the
power-up cycle (see Table 2).
Table 2: Power-up Sequence for LED Status Indication*
Condition Duration
Initial LED Status Indication 80 seconds
Initial LED Status Indication
(if excessive electrical noise is present) 4 minutes
*Refer to Electrical Specifications for start-up time in conjuction with panel alarm veri-
fication.
NOTE: If, during power-up, the detector determines there is excessive electri-
cal noise in the system such as those caused by improper grounding of the
system or the conduit, both LEDs will blink for up to 4 minutes before display-
ing detector status (see Table 2).
After power-up has completed and the detector is functioning normally within
its listed sensitivity range, the green LED blinks once every five seconds. If the
detector is in need of maintenance because its sensitivity has shifted outside
the listed limits, the red LED blinks once every five seconds. When the detec-
tor is in the alarm mode, the red LED latches on. The LED indication must not
be used in lieu of the tests specified under Testing.In a freeze trouble condi-
tion, the red LED will blink once every 10 seconds (refer to Table 1).
To measure the detector’s sensitivity, the i3Series Model CSENS-RDRA Infra-
red Sensitivity Reader tool (see Figure 4) should be used. Refer to instructions
manual I56-2219 for the proper use of the CSENS-RDRA.
Models C2WTR-BA and C2WTA-BA also include an output that allows an op-
tional Model RA400ZA Remote Annunciator to be connected.
Mounting
General spacing guidelines are 30' × 30', with each detector covering 900 ft2
under maximum conditions.
Consult CAN/ULC S524, the local Authority Having Jurisdiction (AHJ), and/
or applicable codes for specific information regarding the spacing and place-
ment of smoke detectors.
Each i3Series detector is supplied with a mounting base that can be ceiling- or
wall-mounted:
1. To a single gang box, or
2. To a 31⁄2-inch or 4-inch octagonal box, or
3. To a 4-inch square box with a plaster ring, or
4. Direct mount or to ceiling using drywall fasteners.

Figure 1: Mounting of Detector
S0121-00
The i3Series heads and bases are keyed so that all heads will only fit into their
respective bases. One model 4-wire relay base will accept the C4WTR-BA,
C4WTAR-BA and C4WITAR-BA detector heads and no others. The C2WTR-BA,
C2WTA-BA and C4WTA-BA will only fit into their respective mounting bases
and no others. The heads and bases are clearly identified as either 2-wire or
4-wire. When mounting the i3Series, ensure that the head is mounted to the
correct base, and the test switch is aligned with the tamper release tab.
Tamper-Resistant Feature
The i3Series detectors include a tamper-resistant feature that prevents re-
moval from the mounting base without the use of a tool. To engage the tam-
per-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.
Installation Guidelines
The i3Series detectors represent an advancement over the previous sounder
and Form C relay models and are designed to be used with the C2W-MOD2A
and CRRS-MODA only. Do not mix detector models on a zone.

Wiring Installation Guidelines
All wiring must be installed in compliance with the CAN/ULC S524, Canadian
Electrical Code, applicable state and local codes, and any special requirements
of the local Authority Having Jurisdiction.
Proper wire gauges should be used. The conductors used to connect smoke
detectors to the alarm control panel and accessory devices should be color-
coded to reduce the likelihood of wiring errors. Improper connections can
prevent a system from responding properly in the event of a fire.
The screw terminals in the mounting base will accept 14–22 gauge wire. For
best system performance, all wiring should be installed in separate grounded
conduit; do not mix fire alarm system wiring in the same conduit as any other
electrical wiring. Twisted pair may be used to provide additional protection
against extraneous electrical interference.
Wire connections are made by stripping approximately 1⁄4-inch of insulation
from the end of the feed wire, inserting it into the proper base terminal, and
tightening the screw to secure the wire in place. Do not put wires more than 2
gauge apart under the same clamping plate.
Two-Wire Compatibility
System Sensor two-wire smoke detectors are marked with a compatibility
identifier located on the label on the back of the product. For two-wire mod-
els C2WTR-BA and C2WTA-BA, connect detectors only to compatible alarm
control panels as identified by System Sensor’s two-wire compatibility chart,
available at www.systemsensor.ca.
NOTE: Models C2WTR-BA and C2WTA-BA are not to be installed on initiating
circuits containing other makes/models of smoke detectors.
NOTE: Style D initiating circuits require the use of a C2W-MOD2A for models
C2WTR-BA and C2WTA-BA

NOTE: Only one C2WTA-BA detector shall be installed on a zone, unless the
panel switches the zone to a reverse polarity, non-current limited power sup-
ply. For panels that do not provide this feature, a reversing relay, System Sen-
sor model CRRS-MODA, may be used. When utilized with the C2WTA-BA, it
allows for more than one detector to be utilized on a loop. Some panels may
require the use of programmable outputs. Refer to System Sensor literature for
further information on the CRRS-MODA. The C2WTA-BA detector shall not be
mixed with other 2-wire detectors on the same zone.

Installation
WARNING
Remove power from alarm control unit or initiating device circuits before in-
stalling detectors.
NOTE: To install units so that corresponding LEDs are lined up, refer to the
“Green LED” indicator on the base.
1. Wire the mounting base screw terminals per Figure 3a or Figure 3b, as ap-
plicable
2. Place detector on the base and rotate clockwise. The detector will drop into
the base and lock into place with a “click”.
3. After all detectors have been installed, apply power to the alarm control
unit.
4. Test each detector as described in Testing.
5. Reset all the detectors at the alarm control unit.
6. Notify the proper authorities that the system is in operation.
CAUTION
Dust covers are an effective way to limit the entry of dust into
the smoke detector sensing chamber during construction. However, they may
not completely prevent airborne dust particles from entering the detector.
Therefore, System Sensor recommends the removal of detectors before begin-
ning construction or other dust producing activity. When returning the system
to service, be sure to remove the dust covers from any detectors that were left
in place during construction.

Loop Verification (models C2WTR-BA and C2WTA-BA only)
Loop verification is provided by the EZ Walk loop test feature. This feature is
for use with i3Series compatible control panels or the i3Series C2W-MOD2A
module only. The EZ Walk loop test verifies the initiating loop wiring and
provides visual status indication at each detector. Refer to System Sensor lit-
erature for further information on the C2W-MOD2A.
WARNING
The C2W-MOD2A has replaced the previous model number C2W-MODA. To
ensure proper EZ Walk Test capabilities, do not use the C2W-MODA with i3
model numbers C2WTR-BA and C2WTA-BA.
Table 3: EZ Walk Test Detector Modes

NOTE: The EZ Walk loop test must not be used instead of alarm testing.
Maintenance
NOTE: Before performing maintenance on the detector, notify the proper au-
thorities that maintenance is being performed and the system will be tempo-
rarily out of service. Disable the zone or system undergoing maintenance to
prevent any unwanted alarms. Power must be removed from the detector
before performing maintenance of any kind.
1. Remove the detector cover by turning counterclockwise. (See Figure 5.)
2. Vacuum the cover or use canned air to remove any dust or debris.
3. Remove the top half of the screen/sensing chamber by lifting straight up
(Figure 5).
4. Vacuum or use canned air to remove any dust or particles that are present
on both chamber halves.
5. Replace the top half of the screen/sensing chamber by aligning the arrow
on the screen/sensing chamber with the arrow on the housing. Press down
firmly until the screen/sensing chamber is fully seated.
6. Replace the detector cover by placing it over the screen/sensing chamber
and turning it clockwise until it snaps into place.
7. Reinstall the detector and test. (See the Testing section.)
8. Notify the proper authorities when the system is back in service.

Testing
Detectors must be tested after installation and following maintenance.
NOTE: Before testing, notify the proper authorities that maintenance is being
performed and the system will be temporarily out of service. Disable the zone
or system undergoing maintenance to prevent any unwanted alarms.
Ensure proper wiring and power is applied. After power up, allow 80 seconds
for the detector to stabilize before testing.
Test i3Series detectors as follows:
A. Test Switch
1. An opening for the recessed test switch is located on the detector hous-
ing (See Figure 4).
2. Insert a small screwdriver or allen wrench (0.18"max.) into the test
switch opening; push and hold.
3. If the detector is within the listed sensitivity limits, the detector’s red
LED should light within one second.

B. Smoke Entry Test
Canned aerosol simulated smoke (canned smoke agent) may be used for
smoke entry testing of the smoke detector. Tested and approved aerosol
smoke products are:
Manufacturer Model
Home Safeguard Industries 25S, 30S
SDi CHEK02 and CHEK06
SDi SOLOA4
SDi SMOKESABRE-01
When used properly, the canned smoke agent will cause the smoke detector
to go into alarm. Refer to the manufacturer’s published instructions for proper
use of the canned smoke agent.
CAUTION
Canned aerosol simulated smoke (canned smoke agent) formulas will vary
by manufacturer. Misuse or overuse of these products may have long term
adverse effects on the smoke detector. Consult the canned smoke agent manu-
facturer’s published instructions for any further warnings or caution state-
ments.
C. Direct Heat Method
Using a 1000-1500 watt hair dryer, direct the heat toward either of the
thermistors. Hold the heat source about 12 inches from the detector to
avoid damage to the plastic.
NOTE: For the above tests, the detector will reset only after the power source
has been momentarily interrupted. It is not necessary to reset the model
C4WITAR-BA, when smoke is used to initiate the alarm.
When testing the C4WITAR-BA model, pressing the test switch will result in
a non-latching local alarm that does not alarm at the control panel. Once the
test button is released, the unit will return to its standby condition. Only the
fixed-temperature heat sensor will cause the C4WITAR-BA to initiate an alarm
at the panel.
If a detector fails any of the above test methods, its wiring should be checked
and it should be cleaned as outlined in the Maintenance section. If the detec-
tor still fails, it should be replaced.
Notify the proper authorities when the system is back in service.
