SIGA2-PS Intelligent Photoelectric Smoke
Detector Installation Sheet
Description
The Signature Series model SIGA2-PS Intelligent Photoelectric
Smoke Detector is an intelligent device that uses an optical
sensing chamber to detect smoke. The detector analyzes the
sensor data to determine whether to initiate an alarm.
LED indicator. The LED indicator (see Figure 1 below)
displays the following states:
• Normal: Green LED indicator flashes, no action.
• Alarm/active: Red LED indicator flashes, evacuate the
area.
• Stand-alone alarm: Red LED indicator turns on, evacuate
the area.

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.
• Photoelectric detectors have a wide range of fire-sensing
capabilities and are best suited for detecting slow,
smoldering fires.
• 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.
• 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. The Signature
Series devices can perform this test and the panel can
generate a system sensitivity report.
• To permanently disable the tamper-resist mechanism prior
to placing the detector in difficult to reach locations, break
and remove the plastic lever arm from the base. See
Figure 1, item 1.
To install the detector:
1. Install and wire the base, as described on the installation
sheet supplied with the base.
2. Remove the serial number label from the detector and
attach it to the project documentation.
3. 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.
In the following steps, xxx indicates a variable related only to
marketplace.
Make sure the SIGA2 Testifire Adapter Assembly (model
SIGA2-TSTSPACER) is installed in the Testifire detector tester
before testing. Refer to the SIGA2 Testifire Adapter Assembly
Installation Sheet (P/N 3101942) for further details.
To perform an initial installation test:
1. Remove the detector from its base and verify that the
proper detector address, trouble signals, and messages
are reported.
2. For SIGA2-PS detectors placed in the air ducts, verify that
the airflow is within specifications. See “Specifications”
below.
3. If wired for Class A operation, verify that the detector
continues to operate first with SLC_IN disconnected, and
then with SLC_OUT disconnected. (Refer to the
installation sheet for the base.)
4. Place a momentary ground fault on the SLC circuit to
verify operation of ground fault detection circuitry.
5. Run a system detector sensitivity report on all detectors
and verify that the readings fall within acceptable limits.
6. Perform a sensor function test, as described below.
To perform a sensor function test:
1. If desired, use the fire alarm control panel to put the
detector or zone into a service group for testing. (Refer to
the panel technical reference manual for instructions.)
2. Activate the smoke sensor using No Climb Products
model CHEK02-xxx smoke aerosol spray, a smoke
generator, or the Testifire detector tester per the
manufacturer’s instructions.
Maintenance
To ensure proper operation, plan maintenance in accordance
with the requirements of the authority having jurisdiction. 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 270145 REV 4.0 or later for
additional information and cleaning instructions.
Smoke chamber replacement
Replace the smoke chamber whenever cleaning the detector
does not restore the panel to normal conditions. Replace with
model number 2-SPRC1 using installation sheet P/N 3101860.
