Alternate Bgm Source To Rstu, Rdsu, Peku, Pesu, Or Pstu Installation; External Bgm Installation; Relay Control Options And Door Lock Control - Toshiba Strata DK 280 Installation Manual

3. Set the SW4 switch to either SPO or SPI, as
required:
n
n
SPO-Directs external page and non-
amplified BGM to the HESB or external
amplifier (pins 13 and 38).
SPI-Directs external page and BGM through
the on-board 3-watt amplifier to the external
speaker output (pins 25 and 50).
4. When using an HESB or external amplifier for
paging/BGM, adjust volume using the HESB or
amplifier volume control.
5. When using the internal amplifier for paging/BGM,
adjust the volume using the volume control (VRl)
on the PIOU/PEPU PCB.
6.2.4 Alternate BGM Source to RSTU,
RDSU, PEKU, PESU, or PSTU
Installation
A BGM source can be connected to a station PCB to
send music to all electronic/digital telephone speakers
and to the external page system via a PIOU, PIOUS,
or PEPU. The BGM source is separated from the
MOH source connected to the RCTU PCB. Connect
the BGM source to the RSTU, RDSU, PEKU, PESU,
or PSTU in accordance with the following steps
(Figure 6-4):
1. Access Program 10-2. Set LED 09 to ON, if the
BGM source will be connected to circuit 3 on a
PEKU. If the source will be connected to circuit 8
on a PESU, set LED IO to ON. If connecting BGM
to RSTU, RDSU or PSTU, LED 09 and 10 should
be off.
2. Identify (assign) the BGM slot with Program 19.
3. If connecting the BGM source to a PEKU or
PESU: Connect the PEKU tip and ring of circuit 03
to the 6OOQ or 8Q output of the BGM source per
Figure 6-4, or connect the BGM output to circuit 8
of a PESU.
- or -
If connecting the BGM source to a RSTU, RDSU
or PSTU: Connect circuit 2 of the RSTU, RDSU or
PSTU to a customer-supplied isolation transformer
and BGM source per Figure 6-5.
Note:
The isolation transformer protects the BGM
source from potentially damaging RSTU,
RDSU or PSTU voltage. Some music sources
which are designed for telephone system
applications may have this protection built-in
and do not require the transformer. (Consult
the documentation provided with the music
source.)
If the BGM source is connected to either a W5 on
the PEKU or W7 on the PESU PCB, cut the strap
(see Figure 6-6). There is no strap to cut on the
PSTU, RDSU or RSTU.
Using the BGM source's volume control, adjust
the BGM volume to the desired level while
listening to BGM via a telephone speaker and/or
the external page speakers. When BGM is sent to
external speakers via a PIOU or PIOUS or PEPU
PCB, use the external amplifier volume control to
balance the BGM and page volume levels.
6.2.5 External BGM Installation
The external BGM options are closely associated with
the external paging options. Refer to Subsection 6.5.1
for externalpaging amplifier installation.
6.3 Relay Control Options and Door
Lock Control
Two relays are provided on the PIOU, PIOUS, and
PEPU PCBs to control the operation of peripheral
equipment (see Figures 6-7 and 6-8):
Note:
Only the PIOU/PIOUS/PEPU with the lowest
Program 03 code (41, 42, or 43) will provide
the relay control function.
q External Page/Door Lock Relay (DET/DER)
n Night Transfer/Music-on-Hold Relay (NHT/NHR)
Each relay may be configured to provide one of two
possible control functions and as normally open
(MAKE) or normally closed (BREAK). Electrical
specifications for the relay contacts are as follows:
Voltage:
n 24VDC maximum
Current:
E 1 ampere maximum
