4009 IDNAC Repeater Installation Instructions
• Only system wiring can be run together in the same conduit.
• Ensure underground wiring is free of all water.
Device wiring guidelines
Consult the following guidelines for devices before you begin the field wiring:
• Only IDNAC devices and other compatible devices are permitted on the SLCs. Consult Compatible devices on page 18 for a list of compatible
devices.
• A maximum of six isolators between any appliance and SLC terminals is permitted. A maximum of 12 isolators for each SLC is permitted.
• A maximum of 30 devices connected directly to any isolator terminal pair is permitted.
• All wiring must be 20 AWG to 12 AWG.
• All wiring must be supervised and power-limited.
• A maximum alarm current of 3 A is permitted.
NOTE: In a Class A extension wiring configuration, the maximum loop current is limited to 3 A. In this configuration, the repeater extends
the wiring distance but does not increase the current available for the devices.
• The maximum cable load is 10,000 feet (3,048 m) per channel. The maximum wire length from the Repeater to any device is 4,000 feet (1219 m).
• The nominal voltage rating is 29 VDC.
• Follow the IDNAC Speaker Wiring Application Guidelines in document 579-1015: EPS Installation Instructions for TrueAlert ES Speaker and S/V
appliances.
Installing ferrite beads
A ferrite bead must be installed on all wiring. To install the ferrite bead, do the following:
1. Loop the wire once though the ferrite bead close to the Repeater field wiring terminals for lowest radiated emissions before the wires leave the
box. Do not loop the ground wire on the AC wiring or the shield wire on shielded cables through the ferrite bead.
2. Secure the ferrite bead with the provided cable ties.

Wiring length tables
Use the following tables to calculate the maximum wiring length starting from the Repeater.
NOTE: Use Table on page 9in place of Table on page 9 for TrueAlertES Speakers and Speaker/Visible appliances.
The maximum wiring length is the shorter of the distance limits calculated by alarm current voltage drop, or by reaching the communications distance
limit.
