BZ-50 BZ-50RC
DESCRIPTION
The BZ-50 and BZ-50RC power packs are the foundation for any low voltage lighting control system. The BZ-50 and BZ-50RC supply
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.
High voltage connections should use at least 14-gauge. For the BZ-50, low voltage wiring should use at least 22-gauge wire. The
BZ-50RC supplies low voltage power via shielded RJ45 cable. Always check local building codes. After initial wiring is complete,
check wiring diagram to verify power pack is wired correctly. Improper wiring can cause damage to power pack, lighting system, and
occupancy sensor.
INSTALLATION AND WIRING
oltage
Low Voltage
Class 2
BZ-50 BZ-50RC
1. Make sure power has been turned off at the circuit breaker.
2. Connect wires as shown in in the following diagrams, depending
on the model and application.
At least three sensors can be powered by the power pack.

WARNING: TURN THE POWER OFF AT THE
CIRCUIT BREAKER BEFORE WIRING.
Installation Notes
1. Power packs should be installed in accordance with state, local and national electrical codes and requirements.
2. Power packs are designed to attach to existing or new electrical enclosures with 1/2 inch knockouts.
3. For the BZ-50, 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.
For the BZ-50RC, connect an FS-C1 or FS-C3 cable between the RJ45 jack-equipped sensor and the BZ-50RC, as appropriate
for the distance between the sensor and power pack. Other cable accessories are shown in the Ordering information section.
NOTE: The BZ-50RC can connect to a sensor with standard wiring terminals by using an FS-C2 cable.
4. The BZ-50 BZ-50RC are Class 2 Output Power Supplies, suitable for parallel interconnection of up to 10 units maximum. These
powerpacks are UL Listed for Interconnection of Power Sources in accordance with the National Electric Code.
5. Refer to occupancy sensor data sheet to determine maximum number of sensors. Power pack mA output is 225mA.

OPERATION
Low Voltage Input (Blue Wire for BZ-50, RJ-45 cable for BZ-50RC, Yellow Wire for BZ-50RC with FS-C2):
The low voltage input wire carries the +12-24VDC maintained input Control ON signal to the BZ-50. Applying 12-24VDC to this input
closes the BZ-50 load relay. Removing the voltage returns the relay to its normal state. This input is intended for sensor or control device
input.
Over Current Protection:
The BZ-50 contains built-in short circuit and thermal protection circuitry that shuts down the +24VDC output (red wire to sensors) to
prevent permanent damage to the power pack. Removing the excess load from the output restores the BZ-50 to proper operation. The
excess load can be connected to another power pack.
LED Indicator:
The LED indicates the following conditions on the BZ-50:
• LED OFF: no power to the BZ-50, or the +24VDC output is shorted.
• LED ON, blinks once every 5 seconds: the relay is closed (load ON).
• LED ON continuously: the relay is open (load OFF).
• LED blinking continuously: current output limit is exceeded (too many sensors are connected to the power pack); +24VDC output
shut down.

DESCRIPTION
Les blocs d'alimentation BZ-50 et BZ-50RC assurent l'alimentation de tous
les systèmes de commande d'éclairage à faible tension. Les blocs BZ-50 et
BZ-50RC assurent l'alimentation à faible tension des détecteurs de présence
et d'autres appareils de contrôle, en modifiant la puissance de l'alimentation
secteur en fonction des signaux émis par les appareils de contrôle. Les blocs
d'alimentation peuvent être raccordés aux boîtes de raccordement existantes
ou être montés dans les chemins de câblage déjà en place.
Les raccordements haute tension doivent passer par des fils d'un calibre
minimal de 14. Le câblage basse tension pour le BZ-50 doit comprendre
au minimum des fils de calibre 22. Le BZ-50RC assure l'alimentation basse
tension à l'aide d'un câble RJ45 blindé. Toujours consulter les codes du
bâtiment régionaux. Après avoir installé le câblage initial, consulter le schéma
de câblage afin de vérifier que le bloc d'alimentation est correctement
raccordé. Un câblage inadéquat peut provoquer des dommages du bloc
d'alimentation, du système d'éclairage et du détecteur de présence.
