Cautions and Warnings
DO NOT INSTALL ANY SIMPLEX
®
PRODUCT THAT APPEARS DAMAGED. Upon unpacking your Simplex product, inspect the contents of
the carton for shipping damage. If damage is apparent, immediately file a claim with the carrier and notify an authorized Simplex product supplier.
ELECTRICAL HAZARD - Disconnect electrical field power when making any internal adjustments or repairs. All repairs should be performed by a
representative or authorized agent of your local Simplex product supplier. Even with electrical power removed, some notification appliances store a high
voltage charge. The high voltage can cause injury or death. DO NOT TOUCH EXPOSED CIRCUITRY.
STATIC HAZARD - Static electricity can damage components. Handle as follows: 1. Ground yourself before opening or installing components.
2. Prior to installation, keep components wrapped in anti-static material at all times.
TrueAlert Speaker Operation
TrueAlert Speakers (see Figures 1 and 2) are notification appliances that reproduce audio signals when activated from a Simplex 4100 fire alarm control
panel (FACP), Simplex 4003 voice control panel, or a UL-listed FACP with compatible audio NAC interface. When the notification appliance emits
sound, it indicates the possibility of an emergency situation that requires your immediate attention.
The TrueAlert speaker is a two-wire appliance that operates only on a standard audio NAC channel (4100/4003) to reproduce amplified analog audio signals.
Input can be either 25 VRMS or 70.7 VRMS that can be selected via a jumper to one of four available audible power wattage levels (¼ W, ½ W, 1W, 2W).

TrueAlert Speaker Wiring
Caution: Connect the wiring to the terminals as shown. Do not loop the wires under the terminals. Break wire runs to provide supervision of the
connections. Do not bring the conduit through the rear of the electrical box. Strip the lead insulation to a maximum of 3/8 inch.
Note: The ceiling- and wall-mount speaker wattage jumper settings and wiring connections are identical. The wall-mount speaker is illustrated below.
1. At the enclosure box, connect the wires to the SPKR + and SPKR - terminals at the rear of the speaker unit. Torque the terminal block screws to 12-15
in/lbs. to ensure proper continuity. See Figure 3.
2. Ensure that the correct polarity is maintained for each unit.
3. Ensure that the RMS value of the connected audio circuit matches the RMS value of the connected speaker. An incorrect tap setting may damage the
speaker. Configure the speaker wattage setting using Table 1. The factory default setting for the speaker is J1 to Tap E (25 VRMS, 0.5 W).
4. The maximum normal supervisory voltage is 40 VDC.
5. Audio NAC wiring must be a twisted pair (TWP).

Mounting the TrueAlert Wall-Mount Speaker
See Figure 4 for mounting the TrueAlert wall-mount speaker to the enclosure box. When surface mounting the speaker, either the 4905-9941 or
4905-9942, a TrueAlert surface mount skirt is recommended. Refer to the 4905 TrueAlert Skirt Installation Instructions (574-790) for this mounting
application.
Caution: Do not bring the conduit through the rear of the electrical box.
1. Tighten mounting screws snugly (do not overtighten). Torque mounting screws to 5-7 in/lbs.
2. For semi-flush mounting, install the box either flush with the wall or with a maximum recess of ¼-inch.

Notes:
1. Refer to the field wiring diagrams supplied with the
4100/4003 for additional NAC wiring information.
2. Notification appliances are rated per individual nameplate
label.
3. Maintain correct polarity on terminal connections. Do not
loop wires under terminals.
4. All NAC wiring connections are supervised and power
limited.

Note: Unlike other TrueAlert peripherals, the speaker does not
support the addressable features of the TrueAlert comm
channel. The TrueAlert speaker is non-addressable and
does not support audio wire T-tapping. Ceiling mount
speakers are not intended for use in air-handling spaces.
