Remote Signaling Connections AS400 | IBM UPS1481 UNIT instruction

OnLine Power

1.Verify that the main input circuit breaker, battery circuit breaker, and output circuit breaker(s), if provided are in the “OFF” position. See illustration 1-2 for the locations of the circuit breakers. See under Section 2-5, Storage for accessing the inside of the unit.

2.Run the power wires up through the center area of the Fire Alarm Back-up UPS1481. Exercise care when working around the battery area.

3.Refer to Section 1-4 for various different installation configurations.

4.Connect the input wires to the input terminal block, TB1. Three (3) wires total: “hot”, neutral (or Hot), and ground.

5.Connect the output wires to the output terminal block, TB2. Three (3) wires total: “hot”, neutral (or Hot), and ground to the appropriate designate locations.

6.Connect the battery wires from external battery cabinet (if provided) to battery terminal block, TB3, three (3) wires total for (+), (-) and Ground.

7.This concludes the electrical connections. Do not apply power to the Fire Alarm Back-up UPS1481 at this time.

2-3-1 Remote Signaling Connections (AS400)

The Fire Alarm Back-up UPS1481 includes the feature of providing dry relay contacts for remote signaling capabilities. Signals available of remote annunciation are:

“UTILITY FAILURE” — This is a normally open contact which closes upon loss of input power to the Fire Alarm Back-up UPS1481 . “LOW BATTERY” — This is a normally open contact which closes when the Fire Alarm Back-up UPS1481 is on battery operation and the batteries are approaching complete discharge.

“ON INVERTER or ON BYPASS” — This is a normally open contact which closes when the Fire Alarm Back-up UPS1481 goes to battery operation.

“SUMMARY ALARM” — This is a normally open contact which closed when the Fire Alarm Back-up UPS1481 has any one of the alarm condition.

If there are no requirements for remote signaling, section 2-4-1 may be skipped.

1.The dry relay contacts for remote signaling are provided on connector (P5) of control board (A2) located on the right door inside of the Fire Alarm Back-up UPS1481. See illustration 1- 2 for exact locations.

2.The dry relay contacts have the following maximum ratings:

200V (AC or DC) maximum

1.25 amperes maximum

30 watts /50 VA maximum, Power Factor 1.0PF

It is imperative that the relay contact ratings are not exceeded. Otherwise, damage to the relays within the Fire Alarm Back-up UPS1481 will occur.
