Description The P421 is a heavy duty watertight telephone for engine room spaces, galley and even for deck mounting. It can be hands free operated, and the hands free function is implemented using a unique digital signal processing technology. It can be used for all PABX systems using plain analogue extension lines, but in conjunction with the AlphaConnect 48 / 128 systems, all the unique features are enabled. The display and keyboard have a red backlight with an automatic dimmer function sensing the ambient light level. The keyboard has a minimum number of keys that allows for single key calls to often used spaces such as Bridge, ECR, STGR etc. The telephone allows for direct calls, where communication can be established without any hands on by the called party. When used with the AlphaConnect 48 / 128 systems, the telephone receives public address calls and alarm calls. An optional handset can be connected for low-speaking conversations, and when the telephone is used in noisy areas, a headset with boom microphone and external PTT can be handled. An external hook/PTT input allows for using a foot operated switch to answer calls. A 10W amplifier is driving an external speaker or loudhailer giving more that 110dB loud and clear sound pressure. A relay contact-set is available for driving rotary lights and horns. The P421 has a watertight design class IP65, operating from –20 to 70 dgs C, and conforms to the IEC60945 standard for maritime equipment. The P421 is powered from 24V DC which is galvanic isolated, as is the 0-24V dimmer input.
