Figure 4: Wiring instructions
Wiring notes:
1.
Assign a maximum of 127 active appliances to a circuit. Assign a maximum of 12 active strobe appliances to a powered circuit. The maximum
wire resistance between appliances is 25 ohms. Refer to the Field Wiring Diagrams of the driving compatible fire alarm control panel for
further instructions.
2.
Notification appliances are rated using an individual module label.
3.
Maintain the correct polarity on the terminal connections.
4.
Terminals 1 through 6 each accommodate two wires, one wire going in and one wire going out to the next appliance.
5.
These appliances are rated to the operating voltage limits of 23-30 VDC. The appliance can fail to operate as intended, and can cause
permanent damage to this equipment if it operates outside of these limits.
6.
Only operate the TrueAlert IDNAC S/V and SO using a compatible power supply and amplifier.
7.
T-tapping is not permitted for Class A wiring.
8.
TrueAlert SLC wiring connections are supervised and power-limited.
Setting the address DIP switch
Each addressable TrueAlert IDNAC notification appliance has a unique address that is set using an eight-position DIP switch (ADDR1).
Assign up to 127 unique addresses an signaling line circuit (SLC), however, the total appliance loading available may be less due to appliance current
requirements.
To set the address complete the following steps:
1.
Unclip the cover from the appliance by inserting a slotted screwdriver, or a similar sized object into the opening at either end of the cover.
2.
Use a non-metallic stylus, or the equivalent to set the switches.
3.
Record the set address.
4.
DIP switch position 8 determines whether this appliance is viewed by the system as an 'ALARM' (OFF) or 'ALERT' (ON) type of appliance.
Confirm the setting for the appliance at this address with the FACP system configuration documentation.
