Relay Connections
The HC4/HC8’s two relays can be programmed to provide automated events such as lift
operation, screen operation, and drapery control. Connections include COMMON,
NORMALLY CLOSED and NORMALLY OPEN. If a voltage trigger is required, an external
power supply can be connected (as shown on page 23) to the HC4/HC8’s relays.
The Relay connections of the PPCM connect to the Relay connections of the System
Controller using Cat5 cables. Use Cat5 to connect to sensors plugged into PPRM panels
located in zones.
Note: Only “Room” punch-downs 1and 2 have connections for relays. This should be
kept in mind when designing the system. See Figure 5-5 below.
Relay controlled devices may also be connected directly to the HC4/HC8.
