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.
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.
