Intermatic IOS-PP24 Quick guide

DESCRIPTION:
The IOS-PP24 Power Pack supplies low voltage lighting control system. The power pack supplies low
voltage power to occupancy sensors and other control devices, switching line voltage in response to
signals from control devices.
INSTALLATION GUIDELINES
Follow these guidelines before beginning installation of the power pack:
• Install power packs in accordance with state, local, and national electrical codes and requirements
• Power packs attach to existing or new electrical enclosures with ½ inch knockouts.
• Most applications require UL listed, 18-22 AWG, 3 conductor, Class 2 cable for low voltage wiring.
For plenum return ceilings, use UL listed plenum approved cables
• The IOS-PP24 is a Class 2 Output Power Supply, suitable for parallel interconnection of up to 6 units
maximum.
• The power pack is UL listed for interconnection of power sources in accordance with National
Electrical Code
MOUNTING THE POWER PACK
NOTE: After the wire connections are made, verify the wire installation was completed properly.
Improper wiring can cause damage to the power pack, lighting system, occupancy sensor, and other
control devices.
NOTE: A customer-supplied junction box is needed to complete this procedure.
1. Make sure power is turned off at the circuit breaker.
2. Punch loose a knockout on the customer-supplied junction box.
3. Insert the power pack nipple into the opening in the junction box knockout.
4. Connect the power pack input wires as shown in Figure 2.
NOTE: The occupancy sensor contains four +12 to 24 VDC input wires to control the load relay. The
inputs may be used in combination or individually depending on the needs of the application. See
the table below for a description of the inputs.
Input (wire) Description
Control ON (Blue wire) Occupancy sensor input. Applying 12 to 24 VDC
closes the relay.
Hold ON (Orange) Time or panel input. Applying 12 to 24 VDC closes
the relay.
Hold Off (Brown) Timer, panel, BAS, or load shed input. Applying
12-24 VEDIC opens the replay.
Manual ON/OFF (Gray) Low voltage momentary switch, if applicable.
5. Refer to Figure 2 to verify the power pack is wired correctly.
OPERATION
The occupancy sensor enables the load to be automatically turned ON/OFF with an occupancy sensor
input, timer, panel, or BAS input. The load can also be manually turned off from an optional low voltage
momentary switch.
OVERRIDING THE POWER PACK WITH MOMENTARY SWITCH (OPTIONAL)
The Power Pack can be overridden from the connected momentary switch. The momentary switch
can override the Power Pack when it is in the Control ON, Hold ON, and Hold OFF states.
OVER CURRENT PROTECTION
The IOS-PP24 Power Pack contains built-in short circuit and thermal protection circuitry that shuts
down the +24 VDC output (low voltage red wire) when the output exceeds 200MA to prevent permanent
damage to the power pack. Removing the excess load from the output restores the occupancy sensor to
proper operation.

INSTALLATION AND CONFIGURATION INSTRUCTIONS

ZERO-CROSSING ACTION FOR RELAY
The Power Pack makes every motion of the relay in the vicinity of AC zero crossing and the deviation of +/- 20% in order to increase the reliability of movement and
life of the relay. The DC does not have zero-crossing protection.
DESCRIPTION OF THE POWER PACK LED INDICATORS
The Power Pack LED, located on the side of the Power Pack, indicates the following conditions:
