Power Supply Voltage Output Specifications:*
Output VDC Switch Position
12VDC SW1 - Closed (Fig. 1b, pg. 3)
24VDC SW1 - Open (Fig. 1b, pg. 3)
*Specified at 25˚ C ambient.
Wiring methods should be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, and with all local
codes and authorities having jurisdiction. Product is intended for indoor use only.
1. Mount unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes in the
enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure's
upper keyholes over the two upper screws; level and secure. Mark the position of the lower two holes. Remove the
enclosure. Drill the lower holes and install the three fasteners. Place the enclosure's upper keyholes over the two
upper screws. Install the two lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 4).
Secure enclosure to earth ground.
2. Set SW1 on the power supply board to the desired DC output voltage (Fig. 1c, pg. 3) (Power Supply Voltage
Output Specification Chart).
3. Connect AC power to the terminals marked [L & N], connect ground to the green flying lead (Fig. 1, pg. 3).
Use 18 AWG or larger for all power connections (Battery, DC output).
Use 22 AWG to 18 AWG for power limited circuits (AC Fail/Low Battery reporting).
4. Measure output voltage before connecting devices. This helps avoiding potential damage.
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing equipment.
There are no user serviceable parts inside. Refer installation and servicing to qualified service personnel.
