Glossary of Terms
(Numbers in parenthesis are the pin outs on P7 connection block required for this feature)
Attendant Port (26/1) - Primary system access is achieved on this pair. A dedicated single line telephone, electronic
key system C. O. line position, or PABX loop start trunk port is required for access.
Background Music Input (28/3) - Input for low level music source (i.e., V-2952).
Clock Activate (31/6) - Input to enable tone source for system broadcast.
Clock C. C. (32/6) - Contact closure follows clock activate to enable external tone source.
Clock Sync (45/20) - Input to reset system time to 0200 hours.
Common Audible C. C. (27/2) - Provides contact closure when attendant station is signalled - follows ring pattern.
Dry Priority Activate (36/11) - Input to enable priority page port when used with telephone system page port.
Emergency Activate (33/7) - Input to enable external tone source for system broadcast.
Emergency C. C. (34/8) - Contact closure follows emergency activate to enable external tone source.
External Tone Input (30/5) - Input for low level tone source (i.e., V-9927A).
Global All Call Activate (43/18) - Control pair for use with multiple V-2924 system that requires all call pages to be
broadcast to all interconnected systems.
Global Page Link (44/19) - Audio pair for use with multiple V-2924 systems that require all call and/or priority
pages to be broadcast to all interconnected systems.
Global Priority Activate (42/17) - Control pair for use with multiple V-2924 systems that require priority pages to be
broadcast to all interconnected systems.
Inhibit (37/12) - If a single line telephone is desired for “Meet Me Answer” a single line “A” lead control telephone
and a 5.1K ohm resistor is required. The tip and ring of the telephone connects to the W/BL (26/1) pair, the “A1”
lead connects to GND (O/BK, pin 12) , the “A” lead has the 5.1K ohm resistor placed in series and the resistor
terminates on Inhibit (BK/O, pin 37).
Night Ring Activate (46/21) - Input to enable night ringing to be broadcast throughout system when contact closure
is detected on this pair.
Override Page Port (35/10) - Secondary system access is provided on this pair. A dedicated single line telephone,
PABX loop start trunk port, electronic key system C. O. line position or page port with contact closure is required
for access. All other system activities are suspended while the override page port is active.
Riot Mode (29/4) - Input to allow attendant port to receive only emergency calls (open - normal mode; closed - riot
mode enabled).
Station 21 C. C. (47/22), Station 22 C. C. (48/23), Station 23 C. C. (49/24), Station 24 C. C. (50/25) - Contact
closure to activate door strike plate from attendant port. Enabled when “*” is pressed twice after communication has
been established between attendant port and station.
