PRODUCT OVERVIEW
The PTM-1 page trigger will interface the page output of a telephone or
paging system to the PR-4Zi and pre-amplifier systems. The PTM-1 Paging
Module is a signal sensing paging adapter which will accept the page output
or other line-level audio output from telephone paging systems, paging pre-
amplifiers, switch triggered voice/sound recording devices etc.
PTM-1 WIRING CONFIGURATION
Use 22-24 AWG twisted pair shielded wire to connect the PTM-1 to the PR-
4Z page input as shown in Figure 1.

By using Voice / Sound Recording devices such as the Visonic Ltd. Model
SP-2, systems may be configured to playback recorded sound (i.e. doorbell
chime, or voice indicators such as "Front Door" etc.). Call Russound for
availability.

PTM-1 SETTINGS
From the bottom of the PTM-1 adjust the trigger sensitivity so that the green
LED comes on when a signal is present at the line audio input. Then adjust the
delay so that the green LED will turn off some time after the audio signal turns
off. This delay will allow a period of time (up to 10 seconds) for any contin-
ued audio signal. Adjust the signal audio level to match the level of audio
from your other sources. This is up to 3 times the input signal up to 6 v peak
to peak. For example, play the CD player at a volume setting then page your
system and adjust the volume level from the PTM-1 to approximately match
the volume of the CD player. This is easily done when used with PR-4Zi pre-
amplifier. When the page signal comes in, the trigger will turn off the audio
source that is playing and allow the audio for the page signal to
come through.
