10.1.1 Configuring the D8129 OctoRelay

Five switches on the OctoRelay determine the relay numbers for the eight relay outputs (Error! Reference source not found.).

10.1.2	Relay Outputs
	Relay outputs can activate when you are
	setting the OctoRelay switches or
	programming the control panel.
	Disconnect equipment connected to relay
	outputs when you perform these functions.

Each OctoRelay output provides a Form C dry contact rated for 1.0 A at 12 VDC. Normally-open, common, and normally-closed terminals are available for each relay output. When an individual output is activated, there is continuity between the normally-open and common terminals. When the output is not activated, there is continuity between the normally-closed and common terminals.

10.1.3 Installation

Set the switches on the OctoRelay before installing it in the enclosure. Refer to Section 10.1.1 Configuring the D8129 OctoRelay on this page.

Install the OctoRelay in the enclosure with the control panel (Figure 2 on page 9) or in an adjacent enclosure that is no more than 1.5 m (5 ft.) from the control panel. Use 1.5 mm (16 AWG) to 0.8 mm (22 AWG) wire.
