APPLICATION This policy applies to all buildings equipped with an automatic fire sprinkler system within the Department’s service area, including contract service areas. These requirements apply to both required and voluntary automatic fire sprinkler systems. OPERATIONAL POLICY Based upon the need for uniformity in application across the Department’s diverse service delivery area, and after careful deliberation, the Department has determined the following: 1. Mechanical tees, outlets or similar fittings installed within any automatic fire sprinkler system are required to have the “coupon” or “token” removed and affixed to the outlet or piping in a permanent and durable manner, within six (6) inches of the tee, outlet or similar fitting. 2. The use of plastic cable ties, tape in any form, and similar methods to secure the “coupon” are not considered permanent and as such, are prohibited. Exception: Plastic cable ties which are listed to UL 21S 3. Where metallic wire is used to secure the coupon, the wire must be 18 AWG or larger, and there must be at least six (6) turns per inch of wire.
