The requestor stipulated that the valves are required to be electrically supervised by applicable code, presumably the IBC. Where conflict in code / standard occurs IBC trumps so NFPA-13 irrelevant. Here's the code sections;
2009 IBC 102.4 Referenced Codes and Standards 901.6 Supervisory Service 901.6.1 Automatic Sprinkler Systems 903.4 Sprinkler System Supervision and Alarms 903.4.1 Monitoring If there's a loss these references may well be cited for the various parties to defend their actions with regards to a nationally recognized building code adopted by jurisdiction.

But the ICC also makes no exceptions for those installations where there is no alarm system to connect any signals. Keep the documentation of the AHJ approval for posterity.

What's the issue here? There are building installations where there is no requirement for a fire alarm system so there is no provision for supervising valves electronically, in those cases you chain or lock them. 8.16.1.1.2* Supervision. 8.16.1.1.2.1 Valves on connections to water supplies, sectional control and isolation valves, and other valves in supply pipes to sprinklers and other fixed water-based fire suppression systems shall be supervised by one of the following methods: (1) Central station, proprietary, or remote station signaling service (2) Local signaling service that will cause the sounding of an audible signal at a constantly attended point (3) Valves locked in the correct position (4) Valves located within fenced enclosures under the control of the owner, sealed in the open position, and inspected weekly as part of an approved procedure Craig L.

An inspector failed to require tamper switches on control valves. The job is complete and there are thousands of pounds of concrete between the control valves and the electrical panel. They placed a chain and lock and the chief declared the chain and lock meet intent...final approved. What say you?
