Installation
Notes
•
This detector does not sense fires in areas where smoke or heat
cannot reach the detector. Smoke or heat 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 sensing capabilities,
and are best suited for detecting slow, smoldering fires. The heat
sensor in this device provides a source of supplemental
information. The heat sensor by itself does not provide life safety
protection.
•
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 install detectors until after final construction cleanup (unless
otherwise specified by the AHJ).
•
Do not use smoke detectors with detector guards unless the
combination has been evaluated and found suitable.
•
Install per NFPA 72
National Fire Alarm and Signaling Code
,
NFPA 720
Standard for the Installation of Carbon Monoxide (CO)
Detection and Warning Equipment
, and UL 2075
Standard for Gas
and Vapor Detectors and Sensors
.
•
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 can perform
this test and generate a system sensitivity report.
To install the detector:
1. Install and wire the base as described on the installation sheet
supplied with the base.
2. Set the detector address. Refer to the panel technical reference
manual for a list of valid addresses. Use a screwdriver to adjust
the two rotary switches on the back of the detector.
(See Figure 3:) Set the left rotary switch (0 through 12) for the 10s
and 100s digit and the right rotary switch for the 0 through 9 digit.
3. Attach the detector to the base by rotating the detector clockwise
until it snaps into the locked position.
4. If required by the AHJ or local codes, affix the supplied CO
Warning Label (P/N 3303928) in proximity to the detector.

Testing
Before testing, notify the proper authorities that the fire alarm system is
undergoing maintenance and will be temporarily out of service.
Test each sensor in the detector.
Caution:
Heat damage. Excessive heat may damage the detector
outer cover. Do not apply excessive heat when using a hair dryer.
When using a Testifire detector tester, you must install a Testifire
Adapter Assembly.
Make sure the Testifire Adapter Assembly (model
SIGA2-TSTSPACER) is installed in the Testifire detector tester before
testing. Refer to the
Testifire Adapter Assembly Installation Sheet
(P/N
3102495-ML) for further details.
Note:
If the CO sensor is programmed as an alarm point, it must
comply with the requirements of NFPA 720.
To perform an initial installation test:
1. Visually inspect each detector and verify that it is installed in the
correct location. Make sure that factors not apparent on the plans
do not adversely affect the detector.
2. Remove the detector from its base and verify that the proper
detector address, trouble signals, and messages are reported.
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. Perform a sensor function test, as described below.
To perform CO sensor function tests:
1. Use the fire alarm control panel to put the detector into accelerated
response mode. (Refer to the panel technical reference manual
for instructions.)
2. Activate the CO sensor using SDI LLC model Solo C6 CO aerosol
spray without covering the head, or using the Testifire detector
tester per the
manufacturer’s instructions.
To perform non-CO sensor function tests:
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 Smoke
Centurion/M8, FireTech Smoke or Smoke Sabre smoke aerosol
spray, a smoke generator, or the Testifire detector tester per the
manufacturer’s instructions.
3. Activate the heat sensor using a hair dryer (maintaining a distance
of three inches) or using a Testifire detector tester per the
manufacturer’s instructions.
