Loudspeaker paging access without universal coupler

1.Determine port assignment of paging zone(s) from loudspeaker paging form.

2.At the main distribution frame, locate the connecting block and terminals assigned to the selected port.

3.On the locally engineered wiring block, place a strap between terminals S and SZ. Place a strap between terminals S1 and SZ1.

4.Install patch cord/jumper wires at the main distribution frame.

5.Connect a 2-pair line cord (modular plug at one end) from the information outlet to the paging amplifier (to the loudspeaker system).

6.Install loudspeaker equipment according to the manufacturer’s instructions.

7.Administer the switch for the new equipment.

Loudspeaker paging with universal coupler

An information outlet provides access to loudspeaker paging. The system side of the main distribution frame connects to a 909A/B universal coupler. Make provisions for the DC power that the 909A/B universal coupler requires, such as a 1151A, 1151A2, or other approved -48VDC power supply.

Six leads (T, R, SZ, SZ1, S, and S1) connect the adapter to an auxiliary trunk circuit pack located in a port carrier.

1.Determine port assignment of paging zone(s) from loudspeaker Paging form.

2.Identify carrier slot and label both ends of an A25D (male to male) cable.

3.Connect a cable from the 909A/B to the system side of the main distribution frame. A wiring block must be locally engineered.

4.Chapter 1, ‘‘909A/B universal coupler’’ provides details of the connections between the 909A/B universal coupler and the wiring blocks.

! CAUTION:

Damage to the 909A/B may occur if the cable is plugged into J3 before all cross-connects are completed.

5.On the 909A/B universal coupler:

■Connect seizure control voltage of from -9 to -70 volts to the PG2/ BZ2 connection (pin 2 of J1). Switching voltage to the PG2/BZ2 connection can be from the 909’s -48-volt supply.

■Connect a -48 VDC power source to the -48 and GRD terminals on the 909A/B.

6.Install patch cord/jumper wires at the main distribution frame.
