Federal Signal Selectone 54GCB Manual De Instalación Y Mantenimiento página 4

2. See figure 2. Insert the tone module into the receptacle, at the rear of the 54GCB,
with the foil side of the circuit board toward the speaker. Make sure that the tone module
connector is fully inserted and that the top edge of the module is beneath the clip. Ensure that
the unit is working correctly after installation.
G. CONNECTOR CARD INSTALLATION (Models AM25CK , AM70CK or 300CKS).
Property damage, serious injury, or death could occur if independent conductors
are terminated together. NFPA 72 requires that both wires of the same polarity must
be terminated separately, so as to provide electrical supervision of the field wiring
connections.
1. See figure 4. Connect the power source positive (+) lead to one of the red speaker
leads. Connect the power source negative (-) lead to one of the black speaker leads. Connect
the additional red and black speaker leads to the next unit or a power supervision relay.
2. See figure 2. Insert connector card into the receptacle at the rear of the 54GCB,
with the foil side of the circuit board toward the speaker (make sure that the connector card is
fully inserted into the receptacle and that the top edge of the card is beneath the clip).
3. See figure 4. Connect one pair of white leads from the connector card to the audio
output of the fire alarm panel and the other pair of white leads to the connector card in the
next unit or a power supervision relay contact and an end of line device.
The connector cards are NOT polarity sensitive, but polarity must be observed when
placing speakers in close proximity to each other.
Audio wires should be sized properly for your application, by your licensed installation
electrician. This cable requires a twisted pair with 18 AWG minimum, and should produce
no more than a 15% signal loss over the length of the cable run.
H. VOLUME ADJUSTMENT.
The volume control is set to maximum at the factory. If the volume level is reduced,
be sure that the alarm signal is loud enough to adequately warn.
After all power is connected and the tone module is installed, the volume of the output
sound level can be set by applying power to the unit and adjusting the volume control, R2. The
location of R2 is shown in figure 2. Clockwise rotation of the control, with a small screwdriver,
increases the volume.
