1.01 The 824 system is a versatile electronic key telephone system designed to meet
the needs of growing businesses.
Modular
design makes the system easy to install and service, and the pro-
grammable features provide a variety of services to meet each
customer's needs.

2.04 In case of power failure, special switching circuitry in
the KSU controls the switching of the C.O. lines to the appro-
priate Power Failure Transfer (PFT) Keysets.
These PFT Keysets,
which are used as regular keysets during normal operation, allow
incoming calls to be answered during a power failure.
DOOR-MATES

2.05 The Door-Mate is an optional piece of equipment which can
be used as a talkback speaker in remote locations.
Keysets are
programmed to answer or call the Door-Mate.

4. MAINTENANCE SUMMARY
4.01 Service is designed for the modular level. In the event of
a failure,
the defective module should be replaced by the service
personnel from their inventory of spare parts.
4.02 All lamps used in the system are solid state, Light-Emitting Diodes (LED'S).
The use of LED's greatly reduces the possi-
bility of burned out components, due to their low failure rate
and minimal power consumption.
4.03 This
manual
contains a
TROUBLESHOOTING
section
and a
DIAGNOSTIC PROGRAMMING section to aid service personnel in diagnosing system problems. The REPLACEMENT PARTS section lists
parts available from Inter-Tel.
4.04 Strict quality assurance standards for
