Model CP2297

24 VDC Transient Protector (Optional)

OPERATION

The 

CERBERUS PYROTRONICS

TM

 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.
