CERBERUS PYROTRONICS
Model CP2297
24 VDC Transient Protector (Optional)
TM
Cerberus Division
OPERATION
The CERBERUS PYROTRONICSTM Model
CP2297 Transient Protector is recommended for
those applications of MXL, MXL-IQ, and IXL that
are susceptible to severe lightning transients.
Model CP2297 provides extra protection to the
basic protection provided in both systems and not
instead of the basic protection. It can be used on
signal lines with nominal voltage of 24 VDC or
less.
In the unlikely event that an overload destroys the
CP2297, the module does not pass power to the
fire alarm control panel; immediate replacement
of the module is then required for continued
operation of the fire alarm panel.
INSTALLATION
1. See Figure 1 for mounting hole locations.
2. Place the unit within the enclosure near the
location where the protected circuits enter the
panel.
Electrical Connections
(See Figure 2)
Three six inch leads are provided for attaching
the CP2297 to the system.
a. The earth ground lead, located by itself, must
be solidly attached to the fire alarm control
panel earth ground.
NOTE: The earth ground wire must be con-
nected to the FACP metal enclosure.
b. There is no polarity for the remaining two wires
that are attached across the analog detector
loop, NAC loop, or network communication lines.
