6. Analogue Voltage Measurements
Analogue inputs 1 & 2 are able to measure voltages between 0V and 36V
(accuracy 0.5v or better) When a voltage on the input exceeds the upper voltage
limit the high SMS messages are sent to the text numbers and dialling commences.
Similarly when a voltage drops below the lower voltage limit dialling commences
and the low voltage message is sent to the text numbers associated with that input.
Input 1 sends SMS messages to channel A numbers or both if not specified. Input 2
sends messages to channel B numbers or both if not specified.
The low voltage message is customised using the CUSTOMXL command (where X is
the channel number) and the over voltage message is specified using the CUS-
TOMXH command.
Analogue inputs can be connected directly to burglar alarm zone terminals. This
allows an individual zone to be monitored even when the alarm is not armed. To
determine the required voltage levels the STATUS message is sent in both active and
in-active states. This reports the voltage of both states so the limits can be set.
The supply voltage is measured and an under and over voltage message is sent to
the master numbers should the supply voltage drop or exceed the maximum permis-
sible voltage. The supply voltage is monitored after the bridge rectifier DC output
(see diagram below). There is therefore a voltage drop of ~0.7V per voltage input
A&B (i.e. VINA and VINB). When connecting a DC voltage to VINA and GND there
will be a 0.7V drop. When connecting DC to VINA and VINB there will be a 1.4V
drop.
As the AC voltage is rectified, the voltage measured will be the peak voltage not
RMS voltage found by multiplying the RMS by 2. Therefore a 24VAC supply will be
measured as ~32V
24 x √2—0.7—0.7 ~32VDC
6.1 Setting the Upper Voltage Threshold Voltage
The VUPPERX command is used to set the upper voltage threshold. When the input
voltage rises above this voltage the upper voltage message is sent. The range can
be set between 0V and 36V. Setting the upper voltage to 36.0V will ensure no upper
voltage messages are sent; the measured voltage must exceed the limit (not be
equal to the limit).
VUPPER2 35.1 initiates dialling and SMS sending when AN2 exceeds 35.1V
VUPPER1 28 initiates dialling and SMS sending when AN1 exceeds 28.0V
VUPPER1 36.0 no measured voltage can exceed 36.0V hence no alerts
6.2 Setting the Lower Voltage Threshold Voltage
The VLOWERX command is used to set the lower voltage threshold. When the input
voltage drops below this voltage the lower voltage message is sent. Setting the
lower voltage to 0V will ensure no lower voltage messages are sent; the measured
voltage must be below the limit (not be equal to the limit).
vlower2 10.0 initiates dialling and SMS sending when AN2 is below 10.0V
vlower1 0 no measured voltage can be below 0V hence no alerts
