4. Wiring of Remote Switch or Input (Telemetry
Input)
VARIO2 is supplied with a pair of Telemetry Input Wires – Orange and
Purple – which are designed to be used with a remote switch or input
from an alarm system, PIR detector, control room, Video Management
system or camera output. The input signal can be volt-free or TTL.
Volt-free input:
Non Polarity Sensitive.Short circuit = Light On
TTL input:
Orange = TTL+ve, Purple = TTL –ve (GND)
0V = Light On, 3V = Light Off
As a default, the Telemetry Input wires (Orange & Purple) are wired
together when shipped from the factory to simulate a volt free input so
the unit automatically turns on/off via the photocell. Any remote input or
switch should be connected to these wires. Snip the end of the cable and
then use the two-core cable as normal.
VARIO2 POE (not premium): Telemetry input not available, Illuminator will
automatically be controlled by the photocell
VARIO2 Hybrid: Telemetry input/TEL/DIM functions operate differently
(factory default = telemetry wires not joined). Please refer to the VARIO2
Hybrid Illuminator Instructions
Under normal operating conditions, a Telemetry Input will activate
the unit only at night provided that the Photocell detects low light
conditions. However, if the photocell is disabled, a Telemetry Input
will activate the unit regardless of ambient light conditions.
The remote input can be used in conjunction with the illuminator in three
different ways as described below:
1.TEL or 2.DIM or 3.TEL+TIMER. The mode of operation is selected by
using the Remote Control.
Note: 3
TEL + TIMER not available on VARIO2 POE (Non Premium) products.
