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

are installed outside the KSU.
Refer to SYSTEM SPECIFICATIONS
for information about selecting batteries for system back-up.
The type and size are critical.
(1) Connect the batteries in series to obtain 24V and make
sure they are connected in correct polarity.
They must
be of the same ampere/hour rating and also have the same
charge/discharge level.
They must be lead calcium grid
batteries and charge at a rate of 2.27V per cell.
(2) On the front of the power supply, set the battery EXTER-
NAL/INTERNAL switch.
This is dependent on the size of
batteries used.

The internal batteries connect to the RED (+) and

the power supply.
A jumper wire is provided to con-
nect the internal batteries.
b.
The external batteries connect to the EXT BATT screw
terminals on the right edge of the power supply.
(5) Turn on the AC power.
(6) Wait approximately six hours for the battery pack to par-
tially charge.
NOTE: Since charging time depends on the amp/hour rat-
ing,
this may vary.
The system charges at a low rate to
protect against battery damage.

A. INITIAL PROGRAMMING OUTLINE
3.01 Below is an outline of the suggested steps to follow to
initially program the system.
Procedures for each step are given
throughout this section.
(1) Set the Data Write switch on the CPU PCB in the ENABLE
position to program the data base.
(2) Initialize the system using the Initialize'switch.
(3) Place the System Mode switch on the CPU PCB in the DATA
SET position.
(4) Enter the system programming data using the Function
switches on the CPU PCB Maintenance Panel.
