Connecting Activators

Activators are external devices such as alarms and lights that can be turned on by the system

in response to an event. Essentially, the unit functions as an on/off switch for these devices.

The unit activates an activator by closing the circuit of its power supply. Up to two activators

can be connected to the unit.

In addition to the activators themselves, you will need the 16 AWG red and black cables to

connect each activator to the unit.

To connect an activator:

1. Install the activator in its desired location in accordance with the manufacturer's

instructions.

Note: If the activator requires an external power supply, you may be able to connect it to

the 12 VDC connector on the rear panel of the unit. However, bear in mind that the unit

can supply a maximum of 500 mA of power. If the devices connected to the unit require

more than this amount of power, you must power some or all of them independently.

2. Connect the two contacts of the activator to the Activators terminal block on the rear

panel of the MVG 400, as illustrated in figure 13.

Note: The wires must be connected to two adjacent contacts in the same group (e.g. the

two contacts of “Out1”), but the polarity does not matter.
