supervised. A UL Listed 10K Ohm, ½ W EOLR is required at the end of the circuit for proper
supervision.

4.4.6 Installing Auxiliary Circuit Connections
Refer to the Remote MIC or RMX Installation Manual for proper connections from 24V OUT, AUX IN, and
CC/NAC to these products. All connections to these products are made from TB6.
4.4.7 Installing Audio Input Connections
The SP40S panel has thirteen inputs. The highest priority input is the on board Push-To-Talk Microphone; it
overrides all other audio inputs. The second highest priority input is the AUX. This could be a Remote MIC or
RMX. Next are the IN1, IN2, IN3, IN4, IN5, IN6, IN7, and IN8 respectively, followed by Night Ring (NR),
Telephone Page (TEL), and Background Music (BGM). Background Music is muted when any other audio input
is initiated. Night Ring (NR), Telephone Page (TEL), and Background Music (BGM) are considered non-alarm
audio and operate only when the panel has 120VAC applied.
4.4.8 Installing Digital Voice Initiating Connections
The Digital Voice Initiating Connections (IN1, IN2, IN3, IN4, IN5, IN6, IN7, and IN8) provide the initiation of
the stored messages in the Digital Voice Section of the SP40S panel. Each initiation circuit requires a Contact
Closure input to trigger the respective voice message. Additionally, each initiating circuit is supervised for an
open. A 10k Ohm, ½ W EOLR is required for each input that is supervised. If an input is not being used,
supervision can be turned off via DIP switch (SW7, positions 1-8).
