4. KEYSETS 
’ 
4.01 Two models of keysets are available for use on the system: 
the Executive Keyset and the Standard Keyset. Photographs of the 
keysets appear on pages 2-10 and 2-11. 
4.02 Features on both keysets: 
l 12-key pushbutton keypad 
l 6 C.O. line keys 
l Integrated (built-in) speakerphone 
l Hearing aid-compatible (HAC) handset 
l Voice volume and ring volume controls 
l Reversible baseplate for wall mounting the keyset 
l 6 feature keys (on the Standard Keyset) 
4.03 
Features on the Executive Keyset only: 
l 6 additional feature keys, totalling 12 
l 12 direct station selection/busy lamp field (DSS/BLF) keys 
l 4-conductor modular jack for a data device equipped with 
a direct-connection modem 
4.04 The DSS/BLF keys provide one-key access to any keyset. 
The 
lamps under the DSS/BLF keys create the busy lamp field, which 
indicates the status of each keyset (idle, busy, call recalling 
from hold, 
forwarding calls, in do-not-disturb, in lock-out) by 
different flash rates. 
4.05. An integrated (built-in) speakerphone is standard in all 
keysets. It allows users to receive and place outside calls and 
to receive intercom calls without lifting the handset. 
Once a 
call is connected, the keyset user can switch back and forth 
between the handset and the speakerphone using the ON/OFF key. 
4.06 The keyset dimensions and weight are: 
Height 3.5 in. (8.9 cm.) 
Width 7.5 in. (19 cm.) 
Depth 9 in. (22.9 cm.) 
Weight 2.5 lbs. (1.1 kg.)

5. OPTIONAL EQUIPMENT 
5.01 
Optional equipment for keysets: 
0 
Headset: A headset can be attached by-unplugging the hand- 
set from the base, plugging the headset into the handset 
jack, and entering a- feature code at the keyset to enable 
the device. Calls are processed using the ON/OFF key. 
The 
GLX keysets are compatible with industry-standard, 4-con- 
ductor, modular headsets that have dynamic microphones or 
with carbon microphone headsets that have an external AC 
power source. Refer to page 7-13 for installation and 
operation procedures. 
0 Han-dset amplifier: Although GLX keysets are equipped with 
hearing aid-compatible 
(HAC) handsets, 
hard-of-hearing 
users may wish to have an adjustible amplifier installed. 
An amplifier also may be requested when the keyset is 
located in a noisy area where users need to increase the 
receiver volume. Inter-Tel recommends the Walker Modular 
Handset Amplifier (part no. WlO), 
an external device that 
is installed between the keyset and the handset (refer to 
page 3-20 for installation instructions). 
The amplifier is 
equipped with a transformer that requires a 1lOVAC outlet, 
and receiver voice volume is controlled by turning the am- 
plifier thumbwheel. This is available from Walker Equip- 
ment Corporation, P.O. Box M, Highway 151 South, Ringgold, 
Georgia 30736, (404) 935-2600. When ordering, specify the 
color: ivory, black, or pearl. 
Modem-equipped data device: The Executive Keyset has a 
4-conductor modular jack to connect a data device, such as 
a data terminal or a personal computer, 
with a direct-connection modem. that is equipped 
To be compatible, the 
modem must have an RJll C.O. line interface. 
It is used to 
communicate with remote data equipment. 
Refer to page 7-13 
for installation and operation instructions. 
5.02 AC voltage surge/spike protection: 
Inter-Tel recommends 
that a protection device be installed with the KSU to sunoress AC 
spikes and transient voltage surges, whether the hot wire, 
neu- 
tral wire, or both wires are simultaneously carrying a surge to 
your equipment. Without the device, 
the system is more suscep- 
tible to damage from AC power line surges and spikes, which could 
cause system malfunctions, false logic, 
electronic components. and/or damage to the 
The cost of a surge/spike protector is 
small compared to the cost of repairs and replacements. 
The de- 
vice is a three-prong, 
AC outlet for the KSU. 15A unit which plugs into the designated 
It must comply with the ANSI/IEEE Stan- 
dard C62.41-1980 (IEEE 587) and must be equipped with RF1 and EM1 
noise filtering in the general range of 5KHz to 30MHz at greater 
than 20 dB of loss.

5.03 Battery back-up: To prevent loss of service in the event 
of a power failure or a brownout condition, there are three 
possible sources for battery back-up. 
Inter-Tel recommends the 
use of the tollowing customer-provided equipment. 
Refer to page 
3-22 for installation instructions. 
l A 30V battery pack can be connected to the KSU, using the 
input labeled BATT 30V. The input requires a Molex 3-con- 
ductor connector (Molex part number 19-09-1032) and three 
terminals (Molex part no. 02-09-1118) or their equivalents 
to be attached to 18AWG wires. Under normal conditions, 
the KSU is powered from the designated AC outlet. 
During a 
power outage, the system is powered by the DC voltage sup- 
plied by the batteries. The DC input represents a 1.5A 
load at 30V under normal operation. After the batteries 
have been used several times, they must be recharged or re- 
placed. Consult your battery representative for assistance 
in choosing the proper batteries. 
l A 30V battery pack and battery charger can be connected to 
the KSU input labeled BATT 3OV, using the same connector as 
described above. The KSU AC power cord is left unplugged 
with this installation. During 
normal operation, 
the 
charger (which is powered from an AC outlet) charges the 
batteries and operates the system. 
During a power outage, 
the batteries alone support the system. The DC input re- 
presents a 1.56 load at 30V under normal operation. Con- 
sult your back-up power representative for assistance in 
choosing the proper charger and batteries. 
l An Uninterrupted Power Source (UPS) unit can be connected 
between the AC outlet and the KSUs AC power cord. The 
unit must be rated at 50 watts or more with a switching 
time of 25 milliseconds or less. A unit with a slower 
switching time may result in calls being dropped when 
back-up power is switched on. 
During a power outage or 
brownout condition, the UPS unit supports the system. 
5.04 External music source: The KSU has an input for a radio, 
tape player, or other music source. For additional specifica- 
tions and installation information, refer to page 3-20. 
5.05 Paging amplifier and speakers: 
The KSU has an output to a 
paging amplifier. For additional specifications and installation 
information, refer to page 3-21.

SITE PLANNIhG CHECKLIST 
Select the KSU location to minimize station cable run 
lengths. DO NOT exceed measurements of 40 ohms or 800 feet 
(243 meters), using 24AWG wire. 
The ohm value is the loop 
measurement; the foot (meter) length is the maximum one-way 
measurement from the KSU. 
Prepare a floor plan for the keyset locations, using a star 
(home-run) configuration. 
Include each keysets intercom 
number (10-21). 
Intercom number 10 is assigned to the sys- 
tem attendant. 
The main distribution frame (MDF) requires a 3 X $-foot 
(0.9 X 1.2-meter), 
3/4-inch plywood backboard. The KSU is 
mounted on this backboard, 
along with connecting block(s) 
and modular jack assemblies. 
Select a wall that is strong enough to support twice the 
weight of the equipment and plywood to be mounted. 
Allow room near the KSU for the paging amplifier, battery 
back-up equipment, 
and the external music source, 
if used. 
To avoid interference, the music source should be placed 5 
to 10 feet (1.5 to 3 meters) away from the KSU. 
Place the KSU within 9 feet (3 meters) of an isolated, ded- 
icated, 105-125VAC, 57-63Hz, 15A, single-phase, commercial 
power source. DO NOT use an extension cord. 
This MUST be an isolated, dedicated, AC circuit for proper 
operation. The ground wire must be dedicated to this out- 
let. Run the power, neutral, and ground wires directly 
from a separate circuit in the breaker box to the KSU out- 
let. DO NOT plug any other equipment into this outlet. 
NOTE: Inter-Tel recommends that the system be equipped 
with a surge/spike protector with RF1 and EM1 noise filter- 
ing for the AC power line. 
cations. Refer to page 2-12 for specifi- 
Make sure there are AC outlets for a music source and a 
paging amplifier, 
if they are to be installed. 
These out- 
lets MUST NOT be on the same circuit as the outlet for the 
KSU. 
The equipment must be located in a climate-controlled room, 
not to exceed 80° F. Refer to page 2-5 for the required 
environmental conditions. 
..: 
The equipment location should not be exposed to direct sun- 
light, high humidity, heat, dust, 
or strong magnetic fields 
(such as heavy motors or large copy machines).

Ample air space should be provided for the KSU since the 
power supply is convection cooled. DO NOT block the cool- 
ing vents located on the top and bottom of the KSU. 
Never 
place anything on top of the KSU. 
If keysets are wall mounted, the wall should be able to 
support twice the weight of the keyset. 
A keyset weighs 
2.5 pounds (1.13 kilograms).
