120Vac Ceiling Mount Occupancy Sensor Power Pack Supply 24VDC

Model: MPP-24 Description: 20Amp Power Pack is the Foundation for any Low Voltage Control System. Such as the MPC-50L, MDC-50L, and other Low Voltage Ceiling Mounted Occupancy Sensor.


120Vac Ceiling Mount Occupancy Sensor Power Pack Supply 24VDC1 DETAILS.jpg

The MPP-24 supplies low voltage power to occupancy sensors and other control devices, switching line voltage in response to signals from control devices. The power pack is attached to existing junction boxes or mounted into fixture wiring trays. 

Low voltage wiring should use at least 22-gauge wire. High voltage connections should use at least 14-gauge. Always check local building codes. After initial wiring is completed, check wiring diagrams to verify the power pack is wired correctly. 

Improper wiring can cause damage to the power pack, lighting system, occupancy sensor and other control devices.

Low Voltage Inputs:

Four+12-24VDC input wires are provided to control the load relay.The inputs may be used in combination or individually,depending on the needs of the application .See the Wiring section for wiring information.

Control ON(Blue)- This input is intended for occupancy sensor input.

Applying 12-24 VDC closes the relay.

Remove the voltage and the relay opems if no other input is holding it closed.

Hold ON (Orange)- This input is intended for timer or panel input.

Applying 12-24 VDC closes the relay.

Remove the voltage and the relay opens if no other input is holding it do sed.

It overrides Control ON input.

Refer to figure 4-Typical Wiring From Power Packs to Motion Sensors

Hold OFF(Brown)-This input is used for timer,panel,BAS or load shed input.

Applying 12-24 VDC opens the relay.

Remove the voltage and the relay can accept any other input.

It pverrides Control ON and Hold On inputs.




1.Make sure power has been turned off at the circuit breaker.

2.Connect wires as shown in the wiring diagram,or as showm in the BI-LEVEL CONTROL section


Installation Notes:

1.Power packs sould be installed in accordance with state,local and national electrical codes and requirnerts.

2.Power packs are designed to attach to exsiting or new electrical endosures with 1/2 inch knockouts

3.Most applications require UL listed,18-22 AWG,3-conductor,Class 2 cable  for low voltage wiring. For plenum-approved cables.

4.Rhe MPP-24 is a Class 2 Output power Supply,suitable for parallel interconnection of up to 6 units maximum.This power pack is UL listed for interconnection of power Sources in accordance with National Electric Code.
