Wiring the Relay Alarm
The IDS switch has a relay with a Normally Closed (NC) terminal pair as well as a Nor-
mally Open (NO) one. Select the connection that suits the application. These terminals are
located on the top panel of the unit. The IDS switch can be connected to an external pow-
ered device such as a siren or light for visual or audible notification of an alarm status.
1. Ensure the power source is off prior to connection.
2. Strip 2x12-20AWG (3.31 mm² -0.52 mm²) twisted pair copper wires 7-8 mm.
3. Loosen the terminal block screws and connect wires into the terminals.
4. Tighten terminal screws. Ensure the wires are securely fastened.
5. Re-insert the Terminal block connector if removed.
6. Turn on power source.
See
Terminal Block Connectors.
Warning:
Ensure power has been removed at the source of the alarm circuit prior to pro-
ceeding with connections to the alarm relay.
Warning:
Ensure the voltage and current supplied by the alarm circuits are within the
stated Alarm Relay specifications.
Warning
: In hazardous location installations, failure to remove the power from the source
prior to completing the wiring connections to the alarm relay could cause an electrical arc
resulting in a possible explosion.
Wiring Digital Inputs
The IDS switch has two digital input connections, one to sense to Dry Contact and one to
sense a Wet Contact.
IN1: This can sense a dry contact. On this terminal pair the IDS switch provides a voltage
and current and can monitor the opening can closing of a dry contact switch.
IN2: This can sense a wet contact. On this terminal pair the IDS switch provides no volt-
age but relies on the input circuit to provide this. See specifications for values.
To connect these:
1. Ensure the power source is off prior to connection.
2. Strip 2x12-20AWG (3.31 mm² -0.52 mm²) twisted pair copper wires 7-8 mm.
3. Loosen the terminal block screws and connect wires into the terminals. For IN2,
ensure that the live side of the input circuit is connected to the + terminal and the
return to the -.
4. Tighten terminal screws. Ensure the wires are securely fastened.
5. Re-insert the Terminal block connector if removed.
6. Turn on power source.
See
Terminal Block Connectors.
Warning:
Ensure power has been removed at the source of the alarm circuit prior to pro-
ceeding with connections to the alarm relay.
