Chapter 4: Installation
• While observing correct polarity, connect the Digital Voice Initiating connections (IN1, IN2, IN3, IN4,
IN5, IN6, IN7, IN8) to the connections on TB7 or TB8 as desired. See Figure 4-1 for TB7 and TB8’s

4.4.9 Installing Ancillary Audio Input Connections
The SP40S panel has three ancillary audio inputs. Listed in order of priority, they are Night Ring (NR),
Telephone Page (TEL), and Background Music (BGM). These inputs do not operate when the SP40S panel is
in the alarm condition or when the input voltage (120VAC) is not applied and the panel is on battery
backup. In addition, these inputs are not supervised.
The Telephone Page input requires input from a Telephone Page Port. The Night Ring input requires a dry
contact closure. The Background Music input requires a line level, 600 Ohm, 1Vrms signal.
1. Connect Telephone Page Input (TEL) to TB5. See Figure 4-1 for TB5’s location. Figure 4-7 is an
enlarged picture of the referred area.
2. Connect Night Ring Input (NR) to TB5.
