F. The base may waive in some applications the requirement for Class A circuits to have separate source and return conduits. For example: connections to two fire pump controllers located in the same fire pump room will require only one conduit from the FACP location to the fire pump room where it will split into two conduits. In this application the return lines will have separate different colored wires (different from the normal source wire color code) from the last interface unit back to the FACP.

G. SCIFs and SAPFs: All indicating and/or signaling circuits going into SCIFs and/or SAPFs shall be dedicated to that SCIF and/or SAPF with direct home runs to FACP and shall be class B circuits. If the only signaling devices inside the secured area is NAC and MNS fault contacts located immediately upon entry, the EOL resistors will be located inside the MNS or NAC amplifier unit. Signaling or indicating circuits shall not use the SCIF and/or SAPF as a passageway to a non-secured area.

Separate dedicated notification circuits shall be used for the following:

A. Notification circuits feeding NAC and MNS panels located at the entrance to SCIF and SAPF areas shall be fed directly with home runs from the FACP and shall be class B.

B. Notification circuits feeding NAC and MNS panels in locations other than SCIF and SAPF areas shall be fed in one of two ways:

7) SCIF and SAPF rooms and areas:

A. Small SCIFs and SAPFs consisting of only one room with small storage room using only one combination strobe(s) and speaker located therein immediately (less than 2” to the strobe mounting boxes) on the conduit entrance to the room: If room is large enough to require more than one combination strobe and speaker, then a NAC and a MNS amplifier unit shall be installed immediately upon conduit entry along with the necessary battery box.

B. Large SCIFs and SAPFs consisting of more than one room shall require a NAC and a MNS amplifier unit installed immediately upon conduit entry along with the necessary battery box.

Notification circuits shall not use the SCIF and/or SAPF areas as a passageway to a non-secured area. Exterior speakers shall not be connected to any notification circuit within the SCIF or SAPF.

C. LOCs shall not be located inside SCIFs or SAPFs.

8) Multi-floor buildings shall have at a minimum separate dedicated signaling or indicating circuit and notification circuits for each floor regardless of the number of devices on each floor. Large numbers of signaling or indicating devices (50 or more, dormitories 20 suites or more) on a floor shall require use of multiple dedicated signaling or indicating circuits. Large numbers of notification devices on a floor may require the use of multiple dedicated strobe or speaker circuits.

Number of devices on a strobe circuit may be limited by the number of speakers on the associated speaker circuit.

9) All strobe amplifiers (aka remote power supplies) shall be labelled “NACxx” or “NACx” where xx or x is a sequential number for a facility starting 01(for 10 or more) or 1 (for 9 or less).

Outgoing strobe circuits from NACs shall be numbered as follows: ASxxy or CSxxy where xx or x is the NAC number and y is the outgoing circuit number from that NAC. AS refers to amber (MNS) strobes and CS refers to clear (Fire) strobes. Outgoing speaker circuits from MNSs shall be numbered as follows: Sxxy where xx or x is the MNS number and y is the speaker output circuit number from that MNS unit.

Speaker circuits shall follow the conduit layout of the strobe circuits (ie a given speaker circuit shall NOT be shared with more than one fire strobe circuit or one amber strobe circuit). MNS amplifier panels may use splitter card(s) provided that if a splitter output is open or shorted it shall not affect the other splitter outputs and if a splitter output is open or shorted, it shall signal a fault to the main FACP panel. Speaker circuits fed from main FACP panel shall be labeled Sx where x is the circuit number. Clear strobe circuits fed from main FACP panel shall be labeled CSx where x is the circuit number.
