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.
Wall mount VO and A/V appliance
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.
Setting the address
Each addressable TrueAlert ES 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.
To access the switch:
