KC2-OS and KC2-OS-CD
Optica Conventional Smoke
Detector Installation Sheet
Description
Optica KC2-OS and KC2-OS-CD conventional smoke detectors use an
advanced photoelectric sensing chamber to discriminate between
smoke from a fire and nuisance smoke from non-fire sources before
signaling an alarm/active condition.
KC2-OS detectors support remote maintenance reporting (CleanMe)
on FX conventional control units that provide this feature. KC2-OS-CD
detectors do not.
The LED indicator (Figure 1) displays the following states:
• Normal: Flashes green every 30 seconds
• Alarm: Solid red
• Trouble (KC2-OS): Flashes yellow every 5 seconds
• Trouble (KC2-OS-CD): Flashes green every 5 seconds

Installation
Notes
• This detector does not operate without electrical power. As fires
frequently cause power interruption, discuss further safeguards
with the local fire protection specialist.
• This detector does not sense fires in areas where smoke cannot
reach the detector. Smoke from fires in walls, roofs, or on the
opposite side of closed doors may not reach the detector.
• To ensure proper operation, store the detector within the
recommended ranges. Allow the detector to stabilize to room
temperature before applying power.
• The dust cover (supplied) must remain on the detector during
installation and be removed prior to commissioning and service.
The dust cover is not a substitute for removing the detector during
new construction or heavy remodeling.
• Do not use smoke detectors with detector guards unless the
combination has been evaluated and found suitable.
• In Canada, install according to CAN/ULC-S524 Standard for the
Installation of Fire Alarm Systems, CSA C22.1 Canadian Electrical
Code, and the local authority having jurisdiction.
• Upon completion of the original installation and following any
modifications or additions to the system, perform a calibrated
sensitivity test per NFPA code.
To install the detector:
1. Install and wire the base, as described on the installation sheet
supplied with the base.
2. Attach the detector to the base by rotating the detector clockwise
until it snaps into the locked position.
Testing
Before testing, notify the proper authorities that the fire alarm system is
undergoing maintenance and will be temporarily out of service.
Cautions
• Under limited circumstances, a relay base may activate when the
detector loses power or is removed from the base.
• To prevent erratic operation of a relay base, once the detector is
removed from the base it must remain powered down (off the
base) for at least 20 seconds before re-attaching it.
To perform an initial installation test:
1. Remove the detector from its base and verify that the proper
trouble signals and messages are reported.
2. If wired for Class A operation, verify that the detector continues to
operate first with IDC_IN disconnected, and then with IDC_OUT
disconnected. Refer to the installation sheet for the base.
3. Place a momentary ground fault on the initiating device circuit to
verify operation of ground fault detection circuitry.
4. Perform a sensor function test, as described below.

2 / 2 P/N 3102737-EN • REV 004 • ISS 25MAY22
To perform a sensor function test:
1. If supported by the control unit, ready the initiating device circuit for
testing. Refer to the control unit’s technical reference manual for
instructions.
2. Activate the smoke sensor using No Climb Products model Smoke
Centurion/M8, FireTech Smoke or Smoke Sabre smoke aerosol
spray, a smoke generator, or the Testifire detector tester per the
manufacturer’s instructions.
Maintenance
To ensure proper operation, plan maintenance (regular or selected) of
the detector in accordance with the AHJ and all applicable governing
laws, codes, or standards. Refer to CAN/ULC-S536 Standard for the
Inspection and Testing of Fire Alarm Systems and NFPA 72 National
Fire Alarm and Signaling Code.
Refer to application bulletin P/N 3102650 for additional information and
cleaning instructions.
