HP300ULX
Product Installation Document
This product follows under the UL1481 Fire Alarm Systems, UL603 Burglary Alarm Systems and UL294 Access Control
Systems. The HP300ULX unit is to be installed in a fail safe mode unless authorized by the local AHJ. This product must
be installed in compliance with Article 760 of the National Electrical Code, NFPA70, as well as NFPA72 National Fire
Alarm Code and all applicable local codes.
1 Description
The HP300ULX is a 12VDC or 24VDC power supply with AC fail and Battery fail supervision. The unit has not been
evaluated as elevator equipment, and is not authorized for bell output in Mercantile applications.

19. Enclosure Dimension: 17”L x 13.5”W x 4.75”H. Accommodates two 12 Volt 12AH batteries. When using larger
batteries, a UL approved enclosure must be used.
3 Installation Instructions
1. Mounting
The power supply should be installed in accordance with all Governing National Electrical and Local Codes. Mount the
power supply securely in the desired location using the four (4) mounting holes.
2. Power Supply Input Connection

Before connecting power, review the entire wiring diagram for correct installation (see Fig. 1). With the AC power
disconnected, connect 120VAC to the Fuse Block as follows; L=Black (HOT), N=WHITE (Neutral), G=GREEN
(Ground). Select the output voltage 12VDC or 24VDC using Jumper J1 of the Power Board J1 OFF=12VDC, J1
ON=24VDC. Voltage is Factory set and Re-Adjusting will void Warranty.
3. Output Connections
Connect the load to the DC (+) and DC (-) terminals observing polarity.
4. Alarm/Trouble Output
a.) AC Fail
relay, which is Fail Safe, will de-energize within one (1) minute.
b.) Battery Fail:
connected or improperly connected, the Yellow LED (L3) will turn ON within one (1) minute and the Battery Fail
output relay, which is Fail Safe, will de-energize.
5. Power Up
When all wiring is complete and checked, switch ON the AC Power. The Green Led (L1) will come ON indicating AC
presence and the AC relay will be energized. Connect Battery observing the correct polarity. For 24VDC use the battery
link provided to connect the two (2) 12 Volt Batteries in series. Secure the enclosure with the 4 screws and with the Key
Lock provided.
NOTE: For UL603 or UL294 applications use a Tamper Switch (Catalog number HPVM3 available separately),
and included enclosure key lock. Connect the tamper switch NC outputs to monitoring device to notify of
enclosure tampering.

power before servicing unit.
For continuous protection against hazard, replace fuses only with exact type and rating. A readily accessible
switched circuit breaker must be available to disconnect main power as required. All power limited wiring should
be routed so that it cannot touch non-power limited wiring; minimum spacing 1/4”. Installation and servicing
should only be made by qualified personnel; contains no user-serviceable parts. Install in accordance with all local
regulations and the National Electrical Code.
4 Maintenance
This unit should be tested at least once a year to verify correct operation in accordance with the following
recommendations;
• Output Voltage Test
Voltage output should be tested under normal load conditions to verify correct levels.
• Battery Test
Battery should be checked for full charge under normal load conditions. This check should verify correct voltage at
both battery terminals and also at the Battery output point on the board to ensure the integrity of all connecting
wiring.
Note: It is recommended to replace the battery at least every 4 years.
