rauland CRT3 Installation Manual

PRELIMINARY

DESCRIPTION MOUNTING PARTS

The CRT3 is a dial-less telephone designed for use with
the Rauland Telecenter@ systems. On the Telecenter IV
and Telecenter TCS, it can serve as a single-link or a multi-

link staff phone. On the Telecenter 5500, it can serve as a
common-line staff phone in conjunctionwith an ADS55 10
Console and an RS503 Staff-Telephone Adapter.

In addition to the standard“tip”and“ring”wiring, the

CRT3 has a second pair of contacts that provide a dry con­tact when the phone is lifted off-hook. This connection
enables the phone to call in when the handset is lifted.

Important: Never connect the CRT3 to the modular
jack of an Administrative Display Telephone: the CRT3’s
extra set of contacts would place a short across the display
lines.

The CRT3 has been approved by the Federal Commu­nications Commission (F2SGBN-7273S-TE-E) .

This Telephone is Not Hearing-Aid Compatible.

The telephone comes with the following mounting

parts:

INSTALLATION

These instructions tell how to mount the telephone.

Wiring diagrams are included in the main Telecenter IV

manual (K&1435), the Telecenter TCS drawings manual

(KI-1550), and in the installation manual for the ADS5510
console (RI-1557). The installer is responsible for comply­ing with all local codes and the National Electrical Code
or the Canadian Electrical Code.

Step 1. For the TC5500, use shielded conductors;
conduit is also strongly recommended. Connect all
shields to ground (see KI-1551). For the Telecenter IV,
use a twisted pair, shielded or unshielded (see RI-1435) 1
Install the electrical box in the wall vertically, and pull
through the wires.

Step 2. Set aside the hont plate from the modular jack.

Orient the module in keeping with its 7OP marking. Find
the unused hole near each screw terminal. Pull each field
wire through the appropriate hole. On the modular jack,
the TI (green wire) and RI (red wire) terminals provide

the conventional “tip” and “ring” telephone contacts; the

AUX (black wire) and GZV (“ground” -yellow wire) provide

a dry contact for calling in.

Step 3. Secure the module to the back box with the
two #6 screws provided. Use the two holes immediately Step 7. To complete the wall-mounting, orient the
inside the module’s studs.

Step 4. Fasten the system wires to the appropriate

screw terminals. Push the front plate onto the module.

Step 5. If the telephone is to be wall-mounted, skip to
Step 6. If the telephone is to be desk-mounted, use the
longer modular cord to connect the phone to the jack,
then set the phone in place. Skip to Step 9.

Step 6. If the telephone is to be wall-mounted, locate
the u&clip reversible hook near the hook switch on the
base. Pull up on this uni-clip until it is clear of the hole,

then rotate it 180” (see the following illustration).

cord to connect the phone to the jack. Align the slots in
the base of the phone with the studs on the module, then
push down on the phone to seat it on the studs (see the
illustration at the right).

Step 8. To make it more diGcult for unauthorized per­sons to remove the phone from the wall, install the lock­ing clip in accordance with the attached manual, KI-1569.

Step 9. Locate the ringer switch (to the right of the
hook switch on a wall-mounted phone). For a TC5500, a
Telecenter IV, or Telecenter TCS single-link phone, turn

the ringer off (down). For a Telecenter IV or Telecenter
TCS multi-link phone, turn the ringer on (up).

Step 10. Program the main system for the desired func-

tions to the phone, then test the phone for call-in, talk­ing, and ringing (Telecenter IV or Telecenter TCS
multi-link only).

Telephone Locking Clip

Installation

RAULAND-BORG CORPORATION l 3450 West Oakton Street, Skokie, Illinois 60076-2951 l [phone]

Description

This locking clip slips into the bottom mounting slot
of a wall-mounted CRT3 or TC4300 telephone to prevent
an unauthorized person from easily lifting the phone from
its mounting studs and stealing it. One clip is enclosed

with each CRT3 and TC4300 telephone.

Installation

Refer to ILO270, on the next page, as needed. Note that

this view is from the wall side of the mounting plate.

Step 1. Install the telephone in the usual way.
Step 2. Orient the clip with its rounded end facing

upward and its perpendicular tab facing you.

Step 3. From the bottom of the phone, start the
rounded end of the clip into the bottom slot on the
telephone. You will need to angle the clip by holding its

bottom end next to the wall.

Hz’nts:If you find it difficult to hold onto the clip, try
grasping its perpendicular tab with a scissors-nosed pliers.
If you need a little extra working space between the

bottom of the phone and the wall, try sliding the phone
further up on its mounting studs (however, the clip must
follow the stud into the bottom slot). Ifyou need still more
space, try loosening the bottom mounting stud about a
quarter-turn (but not so much that the phone will be
loose- test-mount the phone before installing the clip).

Step 4. Push up on the clip until its perpendicular tab
fits into the small hole between the bottom feet on the
phone. Pull the clip against the rear of the phone so that
the perpendicular tab is securely seated.

Removing the Clip

Should it become necessary to remove the clip, insert
a long, thin flat-bladed screwdriver between the clip and

the body of the phone. Pry the bottom of the clip towards
the wall until the perpendicular tab clears the hole in the
phone, then pry the clip downward until it comes out of
the phone.

Important: After a clip has been removed two or three
times, replace it: its diminished resiliency could make it
ineffective.
