Definitions
- One pole of an elevator alarm button is UNITED STATES PATENTS employed to trigger the alarm in the conventional sense while l,7l0,542 4/1929 Landis 340/333 UX another pole of the same button automatically disconnects the 2,942,249 6/1960 Paull 340/327 X car supply voltage triggering the emergency lights.
- the invention is predicated upon the concept of providing a second pole to the alarm test button which automatically disconnects the normal car supply voltage thereby triggering the emergency lights. It is a feature of this invention that both the alarm contact and the power-disconnect selfhold until manually reset, thereby providing continuous lighting (and if desired-alarm) regardless of an intermittent supply voltage.
- FIG. 1 is a block schematic of the inventive circuitry
- FIG. 2 is a detail of the battery charger and light control moduleofFIG. l. 7
- the elevator car lights 10 which are generally recessed in the car ceiling derive their energy from the umbilical cable 12 supplying line voltage to the elevator car.
- Light switch S is disposed at the cab control panel for convenience in operating the elevator lights.
- Voltage supplied to the car is also available via lines 14 and through the normally closed contact ab, of the alarm relay AB to transformer 16 which provides a reduced voltage necessary for the battery charger and light control module 20.
- Battery charger and light control module 20 is connected to the emergency lights 22, which may also be disposed on the inside of the car roof, and the alarm bell 24 which may be disposed, for example, under the car. The latter is coupled via normally open relay contact ab of relay AB.
- the battery charger and light control module supply the emergency lighting battery 40, which is preferably of the nickel-cadmium type which can be repeatedly cycled, and will maintain a peak charge upon being supplied a trickle current.
- the charge and trickle charge is supplied the battery 40 via diode 26 and charging resistor 28 which converts the transformer secondary voltage to DC.
- Relay TR is connected across the transformer secondary and is energized so long as the voltage supply to the cab is not interrupted. Upon interruption, relay TR will cease to hold open the normally closed contact tr, thereby energizing the emergency lights with battery power.
- alarm switch When it is desired to test the alarm of in case of an actual emergency.
- alarm switch a single pole manual switch, is depressed energizing relay AB via battery power. This opens normally closed contact ab and closes normally open contact 017 thereby initiation the following: Contact ab connects the battery 40 to the alarm bell 24, while contact ab, opens the transformer primary deenergizing relay TR and energizing the emergency lights via contact tr. Activation of the switch 5;,
- relay AB which may be of the momentary contact type, also causes relay AB to self-hold via contact ab;, and battery 30.
- the alarm bell In selfholding, the alarm bell will ring and the emergency lights will remain in operation for as long as desired and unaffected by momentary transitions which would cause a fluttering of relay TR.
- the release of the test circuit is effected manually by the opening of contact S causing relay AB to drop out, and releasing the alarm contact ab and restoring the normally closed line contact 0b,.
- the described arrangement provides an extremely simple and expeditious manner of testing the emergency lights periodically in conjunction with alann bell testing. It may be further seen that in case of an actual emergency situation, the actuation of alarm switch S, and the energization of relay AB will maintain the emergency lights on even during power fluctuations until the circuit is reset manually through switch S;,. If desired, a separate switch S having normally closed contact is provided for convenient alarm bell shut off.
- circuit 30, shown enclosed by the dashed lines may be deleted and contacts ab and ab; replaced by the normally closed and normally opened poles, respectively, of a double pole switch.
- the double pole switch would be of the bistable type having on and off positions.
