Notification UPS- 901 Back-Up Power Supply UPS-901 The UPS-901 is an Uninterruptible Power Supply (UPS) designed for use with the TRX-401 Field Transceiver in WAVES® (Wireless Audio Visual Emergency System) that provides highperformance backup power. Features & Benefits • Dependable UPS power source allows continuous audio output up to 1.25 hours Description • Automatic transfer of load to and from power sources • Balance circuit maintains optimal float charge • Mounts securely to associated TRX via built-in mounting tracks • LEDs show charge and operation status • Units are cascadable for extended operating time* The UPS-901 provides back-up power in the event of a loss of the normal utility power source. During normal operation, the UPS-901 receives a trickle charge from the associated TRX401 unit. A balancing circuit is used to maintain an optimal float charge on the battery. In the event of a power failure, the UPS-901 will automatically supply DC power to the transceiver. In addition, external devices connected to the TRX 15V output will also receive power from the UPS-901. Under these conditions, the transceiver and external devices will operate normally until the battery in the UPS-901 is exhausted. The UPS-901 will automatically transfer the load back to the utility power when the line voltage returns to normal. * The UPS-901 units are stackable (up to one additional UPS-901 unit). A replacement cable (P/N M50-04589) must be ordered for stacking an additional UPS-901 unit. Charging Voltage 12 Volts Maximum Charging Current 1.5 amps Operating Voltage 12V DC nominal Max. Discharge Current 4 amps Transfer Time <1 msec Charging Time (to 90% Cap.) < 6 hours Run Time Two (2) channel continuous amplified audio - 1.25 hours Standby, no audio output - 5 hours (Typical) Dimensions 7.2” H x 7.5” W x 2” D (19.5 x 19.2 x 5.1 cm) Weight 5.94 lbs/2.7 kg (with batteries) Certification UL/CE Architects and Engineers Specifications The WAVES® System shall employ a high-performance Uninterruptible Power Supply (UPS) designed for use with the designated TRX-401 Field Transceiver, as shown in the plans. It is acceptable for use in any WAVES® Mass Notification System. The UPS-901 shall provide back-up in the event of a loss of the normal utility power source. The UPS-901 shall mount to its associated TRX-401 unit by means of a mounting track and is held securely by a set screw. An additional set of mounting tracks shall be provided to piggyback additional units or accept the TRX mounting plate. During normal operation, the UPS-901 shall receive a trickle charge from the associated TRX-401 unit through a balancing circuit to maintain an optimal float charge on the battery. A green LED shall indicate the presence of DC voltage in and a red LED shall indicate normal charging. In the event of a power failure of the normal utility power source, the UPS-901 shall automatically supply power to the transceiver. In addition, external devices connected to the TRX 15V output shall also receive power from the UPS-901. Under these conditions, the transceiver and external devices shall operate normally until the battery in the UPS-901 is exhausted. The UPS-901 shall maintain full operation of its associated transceiver for a period of 1.25 hours under full load (utilizing internal amplifier outputs) and up to 5 hours in standby mode (all functions except internal amplifier output.) The UPS-901 shall automatically transfer the load back to the utility power when the line voltage returns to normal.
