HHEU (Loud Ringing Bell/Headset Upgrade): 
Each electronic telephone may also be upgraded 
to provide a loud ringing bell interface and a 
modular headset jack by installing a loud ringing 
bell/headset upgrade assembly (Figure 2-l 6). 
The assembly consists of a small PCB (HHEU) 
which installs on the main PCB, inside the tele- 
phone, with a plug-in connector (HESC-65).

8.34 External Speaker. 
The external speaker 
option is a 3-watt, 6 inch speaker with a built-in 3- 
watt amplifier. A +12VDC power supply (HACU- 
120) is provided with each external speaker, which 
connects to the speaker’s back panel. An 8’ cord is 
provided to plug in the power supply to a 117VAC, 
60 Hz outlet. The HESB has three applications: 
paging speaker, talk-back speaker,...

10.01 PCTU3 (Common Control Unit): 
The lat- 
est version of the common control unit is PCTU3, 
which contains 
Release 3 software. The PCTU3 
can be installed in DK96, DK56, and DK24. Like 
earlier PCTU versions, the PCTU3 contains the 
system’s main microprocessor and microproces- 
sor bus, battery-protected memory circuits, time 
switch logic, conference logic, and system tones. 
The PCTU3 also has a music-on-hold/background 
music...

1 GENERAL 
1.00 
This chapter defines the installation site re- 
quirements necessary to ensure a proper operat- 
ing environment for STRATA DK systems. Also 
included are input power requirements, site con- 
siderations, cable lengths/network requirements, 
and grounding requirements. 
2 INPUT POWER REQUIREMENTS 
2.00 The systems require an input power source 
of 117VAC nominal (85VAC N 135VAC), 50/60 Hz, 
15 amps. The AC outlet must be dedicated to 
system use, fused, and grounded (refer to Para-...

4 CABLE LENGTHS/NETWORK 
REQUIREMENTS 
4.00 Table 3-A lists system loop requirements. 
Table 3-B lists system network requirements. The 
KSU must be located to allow compliance with the 
specified requirements. 
5 GROUNDING REQUIREMENTS 
5.00 The system requires a solid earth ground for 
proper operation. Failure to provide such a ground 
may lead to confusing trouble symptoms and, in 
extreme cases, system failure. The ground con-...
