Page 2 of 3 RETARD CHAMBER MODEL C-1 The Viking Corporation, 210 N Industrial Park Drive, Hastings MI 49058 Telephone: 269-945-9501 Technical Services: 877-384-5464 Fax: 269-818-1680 Email: techsvcs@vikingcorp.com During a sustained flow of water, the Retard Chamber fills faster than water can drain through the Drain Restriction. Pressurized water fills the Retard Chamber and pressurizes the Water Motor Alarm and/or Alarm Pressure Switch. Pressure surges insufficient to overcome the volume and drain capacity of the Retard Chamber will not activate an alarm. Two Retard Chambers may be installed in series to combat false alarms from systems subject to excessive pressure surges. 6. INSPECTION, TESTS AND MAINTENANCE NOTICE: THE OWNER IS RESPONSIBLE FOR MAINTAINING THE FIRE PROTECTION SYSTEM AND DEVICES IN PROPER OPER- ATING CONDITION. THE VIKING MODEL C-1 RETARD CHAMBER AND ASSOCIATED PIPING MUST BE KEPT FREE OF FOREIGN MATTER, FREEZING CONDITIONS, AND PHYSICAL DAMAGE THAT COULD IMPAIR ITS OPERATION. THE FREQUENCY OF IN- SPECTIONS MAY VARY DUE TO CONTAMINATED OR CORROSIVE WATER SUPPLIES, CORROSIVE ATMOSPHERES, OR ACTIVITY AROUND THE DEVICE. ALARM DEVICES AND OTHER CONNECTED EQUIPMENT MAY REQUIRE MORE FREQUENT INSPECTIONS. REFER TO APPLICABLE CODES, SYSTEM DESCRIPTION, AND TECHNICAL DATA FOR THE EQUIPMENT USED. After installation and prior to each Waterflow Alarm Test: 1. Verify that the Alarm Check Valve and Retard Chamber are trimmed exactly as shown on Viking Trim Sheets with no deviations. The trim size and arrangement is required for proper operation. 2. Inspect and clean the 1/8 inch (3.2 mm) Drain Restriction at least annually. After each operation and Waterflow Alarm Test: 1. Verify that the Retard Chamber and alarm line piping has drained completely and associated alarm equipment has properly reset. 2. Refer to Technical Data for the Water Motor Alarm, Alarm Pressure Switch, and other associated equipment for additional testing and maintenance requirements. WARNING: ANY SYSTEM MAINTENANCE INVOLVING PLACING A CONTROL VALVE OR ALARM SYSTEM OUT OF SERVICE MAY ELIMINATE THE FIRE PROTECTION CAPABILITIES OF THAT SYSTEM. PRIOR TO PROCEEDING, NOTIFY ALL AUTHORITIES HAV- ING JURISDICTION. CONSIDERATION SHOULD BE GIVEN TO EMPLOYMENT OF A FIRE PATROL IN THE AFFECTED AREAS.
