TrueAlert ES Addressable UL Listed Multi-Candela Weatherproof Notification Appliances Installation Instructions
Wiring instructions
WARNING: Ensure that all power is disconnected before starting the installation.
1. At the electrical box, connect the contractor wiring to the CKT + and CKT - terminals at the front of the strobe unit.
2. To ensure proper continuity, use a torque wrench to tighten the terminal block screws to 12-15 inch-pounds.
3. Ensure that correct polarity is maintained for each strobe unit.
4. Signal line circuit (SLC) wiring must be twisted pair (TWP). CKT terminals accept two wires: 12-18 American Wire Gauge (AWG) TWP.
IMPORTANT: Do not bring the conduit through the rear of the electrical box. Strip the lead insulation to 3/8 inches maximum.

Wiring notes
• Assign a maximum of 63 devices to a circuit. The maximum devices with active appliances on a circuit is
50. The maximum wire resistance between appliances is 26 ohms. See the field wiring diagrams of the
driving compatible fire alarm control panel for further instructions.
• Notification appliances are rated using an individual module label.
• Maintain the correct polarity on the terminal connections.
• TrueAlert SLC wiring connections are supervised and power-limited.
• These appliances are rated to the operating voltage limits of 23-31 VDC. The appliance may fail to
operate as intended, and cause permanent damage to this equipment if it operates outside of these
limits.
• Only operate the TrueAlertES A/V and VO devices using a compatible power supply.
• T-tapping is not permitted on Class A wiring.
Setting the address
Each addressable TrueAlertES notification appliance has a unique address that is set using an eight-position DIP switch (SW1). Assign a unique SLC address in the range 1 to 127 (Figure 5). However, the total appliance
loading available may be less due to appliance current requirements.
To set the address, complete the following steps:
1. Remove the cover from the device. See Figure 5.
2. Use a non-metallic stylus, or the equivalent to set the switches.
3. Record the set address.
