Fire-Lite MS-25E Addressable Fire Control Panel - Manual (Page 4)

Equipment used in the system may not be technically compatible with the control. It is
essential to use only equipment listed for service with your control panel. Telephone lines
needed to transmit alarm signals from a premise to a central monitoring station may be out of
service or temporarily disabled. The most common cause of fire alarm malfunctions,
however, is inadequate maintenance. All devices and system wiring should be tested and
maintained by professional fire alarm installers following written procedures supplied with
each device. System inspection and testing should be scheduled monthly or as required by
National and/or local fire codes. Adequate written records of all inspections should be kept.
