SIGA2-PHS(B) Intelligent 3D Multisensor PhotoHeat Detector Installation Sheet

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

Description

The Signature Series Intelligent 3D Multisensor Photo-Heat Detector is an intelligent device that contains a photoelectric smoke sensor and a fixed-temperature heat sensor. There are two models: SIGA2-PHS is white; SIGA2-PHSB is black.

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.

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.

• In Canada, install according to the CAN/ULC-S524

Standard for the Installation of Fire Alarm Systems, the CSA C22.1 Canadian Electrical Code, and the local

authority having jurisdiction.

1. Tamper-resist lever arm on base

2. Access slot for tamper-resist mechanism

3. LED indicator

• Upon completion of the original installation and following any modifications or additions to the system, perform a calibrated sensitivity test per NFPA code. 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.

Test each sensor in the detector. In the following steps, xxx indicates a variable related only to marketplace.

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 SIGA2 Testifire Adapter Assembly.

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. 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.)

3. Place a momentary ground fault on the SLC circuit to verify operation of the ground fault detection circuitry.

4. Run a system detector sensitivity report on all detectors and verify that readings fall within acceptable limits.

5. Perform a sensor function test, as described below.

To perform 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 CHEK02-xxx 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.

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 Technical 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.
