TrueAlert ES Addressable Indoor A/O Notification Appliances Installation Instructions

Cautions, warnings, and regulatory information
IMPORTANT: When the notification appliance emits light or sound, it indicates the possibility of an emergency situation that requires
immediate attention of all occupants.
SAFETY: Always install, maintain, and test notification appliances within their specifications. Failure to follow all safety precautions and instructions
may result in loss of life and property due to non-functioning notification appliances. Some notification appliances use high voltage. To avoid electrical
hazards and avoid damage to appliances, make sure that the electrical power for the Notification Appliance Circuit is disconnected at the control
panel before installing, repairing, or internally adjusting any notification appliances. Even with electrical power removed, some notification appliances
(such as visible strobes) store a high voltage charge. The high voltage can cause injury resulting in death from electrical shock. DO NOT TOUCH
EXPOSED CIRCUITRY.
LOCATION REFERENCE: Location and quantity of appliances required must conform to the applicable local standards and guidelines (the National
Fire Alarm and Signaling Code (NFPA 72); ULC Standard CAN/ULC-S524, Installation of Fire Alarm Systems; the appropriate model building codes,
etc.) and specific requirements of the Local Authority Having Jurisdiction (AHJ). These notification appliances are not intended for installation within
hazardous locations as defined by the National Electrical Code (NEC) or NFPA.

Mounting instructions
Table 2: Kit contents
Kit contents Appliance x 1 Cover x 1 Backplate x1 with 8-32 1 inch mounting screws x 2, and 6-32 1 inch mounting screws x 2.
Not included Electrical box 1-1/2 inch (38.1 mm) minimum depth required: single gang, double gang, or 4 inch (101.6 mm) square.
1. Select the mounting location and install the electrical box using screws suitable for the mounting surface. See Figure 1 for mounting and
location information.
2. Bring the building wiring through the rectangular opening in the backplate.
3. Connect the building wires to the backplate. See Wiring Instructions on page 2.
4. Secure the backplate to the electrical box using the provided hardware. Install with the writing Install this side up at the top. Use a torque
wrench to tighten the screws to 12-15 inch-pounds. Do not over-tighten the screws.
5. Attach the cover to the appliance.
6. Set the appliance settings. See Setting the address DIP Switch on page 3.
7. Attach the assembled appliance onto the backplate.
NFPA 72 requires that
the device is not
less than 80 in. (203.2 cm)
and not greater than
96 in. (243.8 cm) above
the finished floor.

Wiring Instructions
WARNING: Make sure that all power is disconnected before starting the installation.
1. At the electrical box, connect the building wiring to the CKT + and CKT - terminals on the backplate.
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 unit.
4. Signaling 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 7/16 inch maximum.

Wiring notes
• The maximum number of appliances on a circuit or on an IDNAC SLC is 127. The maximum wire resistance between appliances is 26 ohms.
See the field wiring diagrams for 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.
• Terminals 1 and 2 can each accommodate two wires, one wire going in and one wire going out to the next appliance.
• TrueAlert SLC wiring connections are supervised and power-limited.
• These appliances are rated to the operating voltage limits of 17-31 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 TrueAlertES AO appliances using a compatible power supply.
• T-tapping is not permitted on Class A wiring.

TrueAlert ES Addressable Indoor A/O Notification Appliances Installation Instructions
Setting the address DIP Switch
Each addressable TrueAlertES notification appliance has a unique address that is set using an eight position DIP switch (ADDR1). Assign up to 127
unique addresses to an SLC, however, the total appliance loading available may be less due to appliance current requirements.
To set the address, complete the following steps:
1. Insert a number 1 or number 2 Phillips screwdriver, or a similar sized object, into the opening at the bottom of the appliance and unclip the
appliance from the backplate. See Figure 3.
2. Set the switches using a non-metallic stylus, or the equivalent.
3. Record the set address.
