Tamper and Flow Switches

[jusme123]

All Class A wiring. Is there a code requirement for the addressable modules (monitoring TS or FS) be located within a certain distance from the tamper and flow switches? Can the wire to the tamper/flow switch be within the same raceway as the intelligent loop. All Class A wiring.

The only distance requirements would be dictated by the the installation instructions. However, you normally only see loop resistance limitations listed.

You are permitted no more than 20 supervisory devices on one circuit or no more than 5 alarm devices.

When combining the two types, the alarm devices must be before the supervisory devices, since you are using a series parallel circuit the tampers would typically open, and alarms would close.


However, most addressable monitor modules will tell you not to mix alarm and supervisory devices on the same circuit, so I guess the answer would be no.
It's a poor practice, but cost effective.
