THE SCHEDULES.

 

THE FIRST SCHEDULE. Reg. 4.

Auto-Alarms.

1. The function of the auto-alarm is to give warning of the receipt of a distress call on 600 metres when watch is not being kept by an operator.

2. The apparatus must comprise—

(a) a wireless receiver (which shall not form part of the main or emergency (reserve) installation), capable of receiving on a frequency of 500 kilocycles (wave length 600 metres) waves of type A.2 or type B;

(b)a selector, that is to say, a means of selecting the alarm signal and of bringing into action the alarm;

(c) an alarm, that is to say, a means of giving audible warning, such as a bell or hooter.

The apparatus necessary under sub-paragraph (a) of this paragraph must be an integral part of the auto-alarm, and when installed may only be used as such.

3. The apparatus must fulfil the following conditions:—

(a) The wireless receiver must respond without re-adjustment to signals on frequencies between 513 and 188 kilocycles (wave lengths 585 to 615 metres) from a transmitter of type A.2 or type B having a steady note frequency of not less than 100 per second, when the strength of signals is such that the field strength is equivalent to that which would be produced by a transmitter making use of 45 metre-amperes at a distance of 80 miles.

(b)(i) The selector must be operated only by energy received from the wireless receiver, and must respond to all signals as described in sub-paragraph (a) of this paragraph relating to the wireless receiver.

(ii) The selector must be of such design as to operate the alarm when three consecutive dashes have been received by the selector.

(c) The alarm must be operated only by the energy received from the selector.

4. The apparatus must comply with the following tests:—

(i) The selector must in conjunction with the wireless receiver respond to 100 consecutive test calls, produced locally, each call consisting of three consecutive dashes under conditions free from interference.

For the purpose of this test the timing of the beginning and the ending of each of the test dashes shall not differ by more than 1 second from the correct timing of the alarm signal of 12 dashes, as defined by regulation 4. The dashes shall not be of less than 3½ nor more than 4½ seconds’ duration and the spaces of not less than ½ nor more than 1½ seconds’ duration.

(ii) The apparatus shall be installed for 14 days in an area where interference conditions are severe on the frequency of 500 kilocycles (wave length 600 metres), and the selector, in conjunction with the wireless receiver, must not respond in such a manner as to operate the alarm more than twice a week to signals other than the alarm signal or the test signals referred to in subparagraph (i) of this paragraph. During this period tests of the sensitivity of the receiver shall be made in accordance with subparagraph (a) of paragraph 3.

(iii) A further test of 28 days’ duration shall be imposed with the object of ascertaining the reliability of the apparatus under interference conditions. For this purpose the apparatus shall be joined normally to an external aerial, and the energy necessary for operating the apparatus shall be produced locally by a buzzer

 

The First Schedule—continued.

or other suitable appliance coupled to the aerial system. The energy given to the aerial by this means shall be of an amount not less than that furnished for the tests described in sub-paragraph (a) of paragraph 3. Each test call shall consist of the alarm signal. During this period of 28 days a minimum of 500 such test calls shall be made, of which 90 per centum must actuate the alarm, and the alarm must not be actuated more than twice a week by other signals. Adjustments of the apparatus shall not be made more often than once every twelve hours.

(iv) During every third day of the test described in sub-paragraph (iii) of this paragraph, the selector and wireless receiver shall be subjected to varying temperature conditions. For this purpose the selector and wireless receiver shall be enclosed in a chamber, the interior of which shall be raised in one hour to a temperature of 45° C. (113° Fah.), maintained at that temperature for two hours, and then allowed to cool naturally.
