Wiring connections are made by stripping about 3/8-inch of insulation from the end of the wire, sliding the bare end under the plate, and tightening the clamping plate screw.

[5.7] Perform Detector Check

1.Perform STANDBY AND TROUBLE TEST per Section [6.2.1].

2.Perform MAGNET TEST per Section [6.2.2.1]. The RTS451 test of Section [6.2.2.2] may substitute for this requirement.

3.Perform AIR FLOW TEST per Section [6.1.1].

4.Perform SMOKE RESPONSE TEST per Section [6.1.2].

5.Perform SENSITIVITY TEST per Section [6.2.3].

[5.8] Install The Cover

Install the cover using the four screws that are captured in the housing cover. Be certain filters are installed as speci- fied in Section [5.5]. Make sure that the cover fits into the base groove and that all gaskets are in their proper posi- tions. Tighten the four screws.

[6]Duct Smoke Detector Maintenance And Test Procedures

Test and maintain duct smoke detectors as recommended in NFPA 72. The tests contained in this manual were devised to assist maintenance personnel in verification of proper detector operation.

Before conducting these tests, notify the proper authorities that the smoke detection system will be temporarily out of service. Disable the zone or system under test to prevent unwanted alarms.

[6.1] Smoke Entry Tests

[6.1.1] Air Flow

To verify sufficient sampling of ducted air, use a manometer to measure the differential pressure created from air flow across the sampling tubes. The pressure should measure no less than 0.03 inches of water and no greater than 1.4 inch- es of water. The air handler must be operating for this test.

[6.1.2] Smoke Response

To determine if smoke is capable of entering the sens- ing chamber, visually identify any obstructions. Plug the exhaust and inlet tube holes to prevent ducted air from carrying smoke away from the detector head, then blow smoke such as cigarette, cotton wick, or punk directly at the head to cause an alarm. REMEMBER TO REMOVE THE PLUGS AFTER THIS TEST, OR THE DETECTOR WILL NOT FUNCTION PROPERLY.

[6.1.3] Filter Replacement

The filters do not substantially affect smoke performance even when up to 90% of the filter is clogged. Quarterly visual inspection usually suffices to determine whether the filters should be replaced because only a high percentage of contamination affects performance. If further testing is required, compare differential pressure readings with and without the filters installed. If the difference exceeds 10% replace the filters. In no case should the pressure differen- tial fall below 0.03 inches of water.

[6.2] Standby, Alarm, And Sensitivity Tests [6.2.1] Standby And Trouble

Standby — Look for the presence of the flashing green LED through the transparent housing cover. The LED should flash approximately every 10 seconds.

Trouble — If the detector LED does not flash, then the de- tector lacks power (check wiring, panel, or power supply), the detector board is missing (replace), the cover has been missing or not se- cured properly for more than 7 minutes (se cure cover properly), or the unit is defective (return for repair).

Test — The trouble condition can be caused intention ally to verify correct operation of the system. Remove the detector board to cause a trouble condition locally and at the system control panel.

Cover

Tamper — If the cover is removed or not properly secured for a period longer than 7 minutes, a trouble signal is generated to indicate the cover is missing.

[6.2.2] Alarm Tests

[6.2.2.1] M02-04-00 Magnet Test

1.Place the painted surface of the magnet onto the TEST locator on the bottom of the housing (Figure 13).

2.The red alarm LED on the detector should latch on, as should any accessories (i.e. RA400Z, RTS451). Verify system control panel alarm status and control panel execution of all intended auxiliary functions (i.e. fan shutdown, damper control, etc.).

3.The detector must be reset by system control panel, front cover reset button, or remote accessory.
