33
Q

Transmissions from the lobby will be given through the

A

VHF cross band HT. Any transmissions that go through the vehicle repeater will reach the officers or chiefs operating on the command channel of the post radio

34
Q

A unique feature of the VHF HT is the ability to

A

Transmit through the vehicle repeater on several channels

35
Q

If the ICP needs reach a unit in the fire area in an emergency, they can still do so by using the

A

VHF HT and going through the vehicle repeater on the tactical channel. This should only be done for emergency transmissions. Transmissions from the vehicle repeater transmit at 40 watts. The high power could cause interference over a wide area to units operating at another incident on the same tactical channel.

36
Q

The IC can switch channels on the VHF HT in order to transmit on different channels, if necessary. The battalion vehicle repeater will

A

Recognize the signal for the VHF HT and then transmit on the UHF on the same channel. The vehicle repeater will remain on the new channel until it is steered to another channel

37
Q

If units operating are not able to reach the IC in the lobby because of the strength of their HT signal they should

A

Have their message to the IC relayed through the Sector/Branch/ Group under which they are operating

38
Q

One of the primary uses of the post radio is for

A

High Rise operations

39
Q

The post radio can be used in conjunction with the

A

Battalion vehicle repeater

40
Q

The key aspect of the post radio is the establishment of a

A

Command channel at 45 watts. Additionally the IC may utilize the post radio anytime it’s use would enhance communications at an incident.

41
Q

Upon arrival it is the responsibility of the______ to ensure that the post radio is in position at the ICP at every all hands or greater alarm.

A

Deputy Chief

42
Q

Only one operation utilizing a vehicle repeater shall be allowed

A

Citywide. The activation of a 2nd repeater could deactivate the 1st repeater.

43
Q

If a second operation requires the activation of the vehicle repeater, the dispatcher will inform the IC of the second operation that there is already a vehicle repeater in use. The second operation shall use

A

“post to post” to effect communications. The second operation will have to operate on a different command channel so as not to interfere with the initial repeater operation.

44
Q

What are the additional methods to use for communications other than post to post radio

A

1) Post radio to vehicle UHF mobile repeater w/o activating the repeater
2) Post radio to UHF mobile radio in DC/BC vehicles equipped w/o cross band repeater system

45
Q

The 1st arriving Battalion to a high rise incident that necessitates vehicle repeater action shall

A

Notify the dispatcher that they are activating the vehicle cross band repeater.

46
Q

All battalion vehicles shall have the vehicle repeater set initially to

A

Ch 2 the primary command channel.

47
Q

For optimal triangulation of the signal the battalion vehicle should be parked

A

Across the street from the operation.

48
Q

If the dispatcher informs the battalion that a repeater is already in use then the battalion shall use

A

Post to post radio or consider utilization of the UHF side of the vehicle repeater w/o activation of the vehicle cross band side of the repeater.

49
Q

The chief will activate the repeater by

A

Depressing the power on button and the VRS button then remove the VHF HT from the charger. Next turn on both the VHF repeater HT and the post radio

50
Q

Upon leaving the battalion vehicle a check to ensure the link between the vehicle repeater and the post radio will be made. The battalion shall give a

A

Short test transmission through the VHF vehicle repeater HT. A quick “test-test” will suffice. When the transmission is received through the post radio a return test will be given from the post radio. When the transmission from the VHF HT is complete the VHF HT will emit a short double tone. This indicates that the transmission is going through the repeater.

51
Q

Who brings their post radio into the lobby

A

All battalions

52
Q

Who brings their VHF vehicle repeater HT into the lobby

A

Only the battalion that activates their vehicle repeater

53

A

Communication link between the lobby and the fire area pending the establishment of the Fire Sector/Branch on a floor below the fire

56
Q

The 1st arriving BC will give the post radio to the

A

2nd arriving engine officer

57
Q

Upon arrival at the floor below the 2nd engine officer shall establish

A

Contact with the ICP on the command channel via the post radio. The officer will verify that the post radio is in place and give his location to the IC. The 2nd engine officer will then use their HT on the tactical channel to announce to units in the fire area that a communications link with the ICP has been established. Communications will be relayed through the 2nd engine officer. In addition to his duties the 2nd engine officer must maintain the communications link with the lobby until the Fire Sector Supervisor arrives on the floor below.

58
Q

The 2nd arriving BC will report to the

A

Lobby with the post radio set on the primary command channel 2. The 2nd arriving BC shall confer with the IC in the lobby, receive an update on operations, ascertain the location of the 2nd engine officer, leave the post radio at the ICP and proceed to the location of the 2nd engine officer.

59
Q

Upon arrival at the 2nd engine officers location the 2nd BC shall

A

Get a briefing on operations from the engine officer, than take the post radio and establish the Fire Sector/Branch in a favorable location. The 2nd BC will now make an announcement over the primary attack channel on the HT that the Fire Sector is established and give his location. Communications will now be relayed through the Fire Sector.

60
Q

After the fire sector branch has notified all units of his location who does the fire sector notify next

A

Fire sector will now contact the ICP via the post radio on the primary command ch 2 and announce their establishment and location

The 2nd arriving engine officer will ensure that the post radio is obtained from the member operating the elevators

67
Q

If a Battalion is assigned as an Attack Chief, they can leave their

A

Post radio at the Fire Sector. This post radio would be set to the tactical channel (the Fire Sector Supervisor post radio is set to the command channel).

68
Q

Because of its antenna, the post radio is

A

Better equipped to receive transmissions than an HT

69
