Control System Input Scanner, used in conjunction with
SCl/5 or SCl/6 to code information for transmission on
remote control systems. CHl/63. DD 1975.
Scanner Store. Automatic MIC Store. Power requirements
+5V. 4U 57 way double-sided unsupported board with PNl/29J
panel. Supersedes UN23/57. Parent equipment PAlM/99 and
PAlM/lOO. DD 1979. (Code originally allocated in 1976,
this now cancels UN23/57. Required due to units under
SC1/7 designation being in service.)
Clock Drive Changeover Cabinet, for use with a CAl/6, or
similar and contained in an identical cabinet. Comprises a
seconds slave clock to monitor main drive input and manual
changeover switch to select an alternative, unmonitored,
drive source, for driving one clock lamp. Drawing series
SP25l97 refers. Power requirements None. SCPD 1978.
Preset Time Switch Unit. Receives two feeds of timecode
from GE7/6's, selects one as master and compares with
thumbwheel setting. If primed changes state of control
relay when two are equal, and cancels priming. When not
primed sounds an alarm. Used to control changeover between
audio sources. Power requirements 5V 500mA. CHl/48B. DD
1978.
Preset Time Switch Unit. As SEl/2 but contains a 5V
regulator to enable unit to be installed remote from power
supplier. Power requirements 8V d.c. 500mA. CHl/64B. DD
1980.
5 Minute Selection Switching Matrix. Contains four
pinboards each with selection of day of week and time in 5
minute steps. Different size pins used to select 'on' or
'off' pulse output. Driven by pulses from COlO/l. Output
triggers normally fed to UN14/l3 delay unit (used for
transmitter on/off switching). Power requirements 5V
200mA. Chl/65H. DD 1978.
Quarter Hour Selection Switching Matrix. Contains four
pinboards each with selection of day of week and time in
quarter hour steps. Driven by pulses from COlO/l. Output
triggers normally fed to UN14/l3 delay units (used for
transmitter on/off switching). Power requirements 5V
200mA. CHl/65H. DD 1978.
Band 11 Multiplex Diversity Switch. This unit is designed
for use in conjunction with two RC5L/8 re-broadcast
receivers, to form a diversity reception system, switching
at multiplex. This unit also contains a stereo decoder to
provide left and right programme feeds. Power requirements
190-260V 50Hz 25VA. PN3A/53C. Sub-units SEl/6 and CD3/23.
DD 1980. DDMDI 5.379(81).
Band 11 Multiplex Diversity Switch. This unit forms part
of the SElL/5 multiplex switching which provides off-air
diversity reception on Band 11. Power requirements 190-
260V a.c. 50Hz 25VA. CH1/64B. DD 1980. DDM1 5.379(81).
