Connect Wiring

Refer to the following information to connect the wires and cables as required.

NOTES:

•

Relay 3 is allocated specifically for an external washer (not supplied by Pelco).

•

All relays are specified for 32 VDC, 0.5 A.

•

Wiring/cable for UTP and fiber optic are not provided on the wire harness. The installer must provide UTP and fiber optic connections.

WARNING:

When installing this unit, provide access to the communication wires (TX- and TX+) to allow connection to the system for
future software upgrades. Connectors must be installed so that the integrity of the hazardous location is maintained.
These communication wires are required even if the system uses Coaxitron

®

control.
Maximum wire distance for RS-422 data wires is 4,000 ft (1,219 m).

Wiring Distances

The following are the recommended maximum distances for 24 VAC and
100-240 VAC applications and are calculated with a 10 percent voltage drop.
(Ten percent is generally the maximum allowable voltage drop for AC-powered
devices.)
NOTE: Power consumption is 120 VA per unit. Use a powersource with a
minimum of 150 VA.
