A: Power: 14 AWG or larger. Phone: One pair of shielded twisted pair for the telco line (telco wire size varies depending on distance required, 22 gauge standard).

Q: What are the Power requirements for all Code Blue units?

A: See table below.

CODE BLUE UNIT MODEL NUMBER	WATTAGE
CB 1	200
CB I w/ NightCharge	450
CB 1-e	75
CB 1-w	75
CB 2-s	150
CB 2-e	75
CB 4 (no beacon)	7
CB 5	75
CB 8 (no beacon)	10
CB 8 w/ NightCharge	350
CB 9	10
Remote Beacon/ Strobe	30

Q: Why doesn't my strobe turn on when the unit is activated?

A: Try disconnecting the weatherproof gray connector that runs between the phone and the strobe light, and shorting the two conductor pins in the connector that runs to the strobe. If the strobe flashes, there is a problem with the phone. If the strobe doesn't flash, there is a problem with the strobe light. The most common problem is a burned out flash tube. These flash tubes are available as spare parts. If a new flash tube doesn't solve the problem, call Code Blue tech support for additional information.

Q: There was a storm last night, and now the unit won't dial out. The phone works fine at the lab bench, but doesn't operate on location. What happened?

A: Test the integrity of the phone line surge protector by trying the phone with the surge protector, and then bypassing the surge protector. If the phone works without the surge protector, but does not work once the surge protector is reconnected, it is likely that an electric surge or spike blew the telephone protection circuit. These surge protectors are available as spare parts from Code Blue.

Q: The clear strobe top dome on my Code Blue model CB 1 is filling up with water and/or condensation. What can I do?

A: First, be sure there is a ½" gap from the bottom of the CB I to the ground. This gap is needed for proper air circulation throughout the Code Blue unit. In most cases, the condensation in the strobe top dome can be eliminated simply by raising the unit ½" from the ground.

In some extreme locations, condensation may still build up in the top of the strobe dome even if the unit is properly installed. In this circumstance, it may be necessary to purchase a Code Blue passive dome top vent kit. The passive dome top vent kit is installed on top of the Code Blue dome and allows air to circulate throughout the unit, thus reducing the effects of condensation. Contact Code Blue tech support for further information.

Note: A solar powered dome vent fan kit is also available.

Q: The CB3100 speakerphone stays off hook well after the operator has terminated the call by standard hang up?

A: The CB3100 has been programmed to understand a number of hang-up procedures:

1. When connected to a POTS line (plain old telephone system) the phone company switch should provide the hang-up command, known as CPC (Calling Party Control)
2. Another method is: Have the phone line revert to dial tone, the CB3100 will count to 8 seconds and then hang up.
3. If these methods are not available: You will find a Programming feature of the CB3100 in the manual. Command (CMS) 64 in the programming section.

• Silent time out CMS 64XX#. XX refers to a two digit representation of time 05~99 seconds. When this mode is engaged the phone will now look to complete one of the following timing cycle of events
  • Revert to dial tone and count 8 seconds of dial tone.
  • Time silence's for the programmed period of time.
  • Count 30 repetitions of the reorder tone.
  • Last on the list is: the operator (guard) may choose to hold the pound # key down for 2 seconds (must have the long DTMF tones available, not burst tones) on the their phone to force the CB3100 to hang up. 

Q: How do I get the CB3100 to work with an auto dial phone line?

A: First, refer to the industry standard for terminology:

Ring-down trunk (Hot line) per MCI Communication Online Library

Ring-down

1. A circuit or method of signaling where the incoming signal is activated by alternating current over the circuit.
2. The signaling method used in manual systems in which picking up one telephone automatically rings another. The ringing telephone gains an operator's attention and initiates a current that is sent over the line to engage a lamp and drop a self-locking relay.

   Programming Ring down mode: CMS 35 4 #

   1. You must call the CB3100 and enter program mode.

   2. Then address the command line 35 ( 4 ) # this will set the CB3100 to operate in the Ring down mode.

   3. Close out of program mode if you have finished programming by holding # for 2 seconds.

   4. To defeat this mode and return to default settings, enter 350#.

Q: Will the CB3100 phone work with a VOIP (Voice Over Internet Protocol) System?

A: Connecting the CB3100 speakerphone to a VOIP system is very similar to connecting to a digital phone system. The customer simply needs to contact their VIOP system vendor and tell them the quality of analog devices that they will be adding to their system and the vendor will present them with their options. Because most Digital and VOIP phone systems are proprietary, the only way to interface to them is by using an interface from that system's manufacturer. The same interface could be used to connect a fax machine, dial-up modem or any other single-pair, analog device.
