on/alaRm
- Open collector output pulses for
two seconds when a valid ON signal or ALARM
signal is received.
PanIC/tamPeR
- Open collector pulses for
two seconds when a Panic or Tamper alarm is
received.
aUX
- Open collector pulses for two seconds
when an AUX signal is received from a four
button radio key.
Note 1: Ness radio keys which have an AUX
button include:
100-067 RK4 Radio Key
106-167 RK4B Radio Key
106-299 RK4P Prox Radio Keys.
Note 2: The AUX button on the grey 106-178
RK3+1 radio key sends an ON signal not an
AUX signal.
low Batt
- Open collector output pulses
for two seconds when a Low Battery signal is
received from either a Radio Key or an Alarm
Device. Connect a 12v beeper or optional relay
for connection to an alarm zone if required.
Note: SCR+ does not identify which device has
caused the Low Battery alarm. The batteries of
all the transmitting devices should be checked.

The Inhibit Input can be used with an output
from a control panel to synchronise the relay
and the On/Off buttons of a radio key to the
state of the control panel.
The Inhibit Input is only active when the relay
is set for Pulse mode for On/Off signals, see
Operation Table 2, page 6.
The input should be pulled below 0.5v to be
Low and above 1v to be high. The input is high
when left open.
Power requirement is 12vDC (10-15vDC).
The Open Collector
outputs are switched
low. 100 mA maximum
sink current.
