INTRODUCTION

The PagePal unit interfaces most telephone sys­tems (PBX, KTS, Centrex) to virtually any public
address audio system.
In addition, PagePal fur nishes input s for customer
provided background music and auxiliary inputs
(such as an attendant microphone, a radio
receiver, recorded announcements). Control
inputs are provided for tones generated by th e
PagePal. PagePal can be placed on a desk or
shelf, or mounted to a wall.

Note: Only line level microphones may be used
with PagePal.

OPERATION

Inputs are routed to the output with the followi ng
priority (highest to lowest):

1. Attendant access for emergency announce­ments.

2. Telephone Access for general paging.

3. Alert Tone 1 (siren) for evacuation warning.

4. Alert Tone 2 (chime) for time clock, door bell,
security alert, etc.

5. Night bell for after-hours calls to ring over the
public address system.

6. Music input for background music.

7. Override or busy tone is returned to the tele­phone user if a higher priority input is active.

8. Call confirmation and preannouncement tones
may be optioned.

9. An optional contact closure output is provided
to control auxiliary equipment (music/page
switching, recorder logging, etc.).

10. St ation access mode features:

- VOX (Voice Operated Switch)

- Maximum length off-hook timer.

- Responds to open loop disconnect).

- Dial tone detection and disconnect.

11. Loop Start Supervised (LSS) access mode
provides VOX and maximum length off-hook
timers for use with a Loop Start Trunk Port.

INSTALLATION

Input Access / Switch Settings

A four position slide switch is used to select the
telephone access mode.

• (LS) Loop Start
Used with a Loop S t art Trunk Port of a PBX or
Key System, or a dedicated phone set.

• (GS/LSS)

Ground Start/Loop Start Supervised

Access from a PBX Ground Start Trunk Port.
In this mode, the PBX ground must be con­nected to pin 1 of the 20-pin connector on the

PagePal
the PagePal.

In Loop Start Supervised mode, pin 7 of the
PagePal must be connected to pin 1 on the
20-pin connector to allow supervisi on of the
Loop Start Trunk Port. The PagePal will super­vise the connection, and will automatically dis­connect the line if no voice is detected on the
line for 20 seconds or if the line r emains active
(off hook) for more than one minute.

Main Output

Adjusts level of output. Full clockwise rotation
provides 14 dBm gain.

Set the Main Output level first using telephone
input, then adjust Attendant and Music Inputs for
an appropriate relative level.

Attendant Input

Adjusts level of Attendant Input relative to the
Telephone Input. Adj ustment ran ge is from 0 dBm
to less than -30 dBm.

Music Input

Adjusts level of Music Input relative to the Tele­phone Input. Adjustment range is from 0 dBm to
less than -30 dBm.

TECHNICAL ASSISTANCE

When calling, have a VOM and a telephone test
set available and call from the job site. Call (540)
427-3900 and ask for PagePac Technical Sup­port, or call [phone] for Valcom 24-hour
Automated Support or visit our websites at http: //
www.pagepac.com and www.val com.com.

• (SA) Station Access
Used with a standard (ANALOG) station port
on a CENTREX, PBX, Key System, or Central
Office subscriber li ne. Use a two-wire RJ11
cable in this mode. The PagePal r eceives t alk
battery and ring voltage from the host system.

• (DL) Dry Loop
Interfaces with the Page Port of a PBX or Key
System, or an Auxiliary port of a PBX. This
input shall respond to resist ances from 0 to 1K
Ohms and will ignore resistance greater than
10K Ohms. Use a four-wire RJ11 cable in this
mode. Dry Loop is a four wire connection.
Pins 2 and 5 of the RJ11 are intended to inter­face with the control leads of t he host system,
while pins 3 and 4 connect to Tip and Ring, as
usual. See Table 2 for pinout descriptions.

Should repairs be necessary, attach a tag to the
unit clearly stating company name, address,
phone number , contact person, and the nature of
the problem. Send the unit to:
