Hardware Options
Backup Battery
The system power supply supports a backup battery package rated at 24 volts, 0.7 amperes/hour. A
trickle-charge maintains the battery at 95% efficiency, applies system cutover to battery when facility
power is removed, and provides system shutdown when battery power falls below a specified level.
External Music
Up to one (customer supplied) monaural music sources can be connected at the optional equipment
jack (JR5) located on the left side of the KSU. The connected music is available to the system only if
programmed using system Programming (PROG. 1-37 and 2-75) the impedance of the music source
must be 32ohms with power at approximately 100 milliwatts.
Note: An internal music source is available and is selected through system programming by default.
Note: In some circumstances there may be broadcast restrictions associated with the external music
source. Check with the sources original distributor and/or the radio station for copyright and
broadcast restrictions concerning background music and music–on-hold.
External Paging
The system supports a customer supplied amplifier for paging access to a single paging zone. The
amplifier can be connected at the optional equipment jack (JR5) located on the left side of the KSU.
Access is provided for 8 paging zones. The output for zones 1-7 must be connected through station
ports and must be assigned by system programming (PROG.3-35).
External Relays
The system supports 2 external relays for multiple functions such as station, trunk, loud-bell, Paging,
Music, and Door strike control. The customer supplied optional equipment can be connected at the
optional equipment jacks (JR4) located on the left side of the KSU. The contacts can be programmed
(PROG.3-40 and 3-41) for normally “open” or “closed” depending on customer needs.
Caller I.D.
The system supports Caller I.D. offering Name or Number display. The caller I.D feature is
programmed in the system database (PROG.1-05, 2-26 and 2-73). Caller I.D. number is reported to
SMDR print-out (see figure 6).
