System Sensor i3 Series Installation And Maintenance Instructions

INSTALLATION AND MAINTENANCE INSTRUCTIONS
Series
Photoelectric Smoke Detector
Models: C2W-BA, C2WT-BA
C4W-BA, C4WT-BA
Before Installing
Please read thoroughly System Sensor manual A05-1003, Application
Guide: System Smoke Detectors, which provides detailed information
on detector spacing, placement, zoning, wiring, and special applica-
tions. Copies of this manual are available from System Sensor at no
charge.
NOTICE: This manual shall be left with the owner/user of this equip-
ment.
IMPORTANT: This detector must be tested and maintained regu-
larly following CAN/ULC S536 requirements. At a minimum, cleaning
should be performed annually.
General Description
Models C2W-BA and C2WT-BA are 2-wire photoelectric smoke detec-
tors; models C4W-BA and C4WT-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, maintenance or screen replacement. Should
it become necessary, the screen/sensing chamber is field replaceable.
Models C2WT-BA and C4WT-BA also feature a restorable, built-in,
fixed temperature (57.2°C) thermal detector and are also capable of
sensing a freeze condition if the temperature is below 5°C.
All i 3 Series detectors are designed to provide open area protection.
Two-wire models must be used with compatible ULC Listed panels
only.
When used with an i 3 Series compatible control panel or the i 3 Series
C2W-MODA module (refer to installation manual D500-46-00), the
C2W-BA and C2WT-BA are capable of generating a "maintenance
needed" signal. The C2W-MOD2A can indicate a need for cleaning,
replacement, or a freeze condition (C2WT-BA only) at the control panel
or module.
Installation of the C2W-BA, C2WT-BA, C4W-BA, and C4WT-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 installed 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:

Alarm
After an initial power-up delay, the red and green LEDs will blink syn-
chronously once every ten seconds. It will take approximately 80 seconds
for the detector to finish the power-up cycle (see Table 2).

(if excessive electrical noise is present)
*Refer to Electrical Specifications for power up to alarm time.
NOTE: If, during power-up, the detector determines there is exces-
sive electrical 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 displaying 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 detector 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 condition, the red LED will blink once
every 10 seconds (refer to Table 1).
To measure the detector's sensitivity, the i 3 Series Model CSENS-
RDRA Infrared Sensitivity Reader tool (see Figure 4) should be used.
Models C2W-BA and C2WT-BA also include an output that allows an
optional Model RA400ZA Remote Annunciator to be connected.
Mounting
Each i 3 Series detector is supplied with a mounting base that can be
mounted:
1. To a single gang box, or
2. To a 3 / -inch or 4-inch octagonal box, or

3. To a 4-inch square box with a plaster ring, or
