An system is provided for testing emergency lighting units using a receiver connected to the emergency lighting unit and a portable transmitter operable remotely with respect to the emergency lighting unit. The emergency lighting comprises a transfer relay for switching a battery between a primary power source and a lamp. A TEST button and the receiver each include a normally closed contact switch connected in series with each other, as well as with a primary power source input and transfer control circuitry. The transmitter generates encoded signals for wireless transmission to the receiver as long as a control switch on the transmitter is being activated by a user. The receiver receives and decodes the encoded signals and opens its normally closed relay as long as encoded signals are being received, causing the transfer control circuitry to activate the transfer relay to switch the battery from the primary power source to the lamp. The transmitter terminates transmission of encoded signals when the user deactivates the control switch. The receiver then closes its normally closed relay when encoded signals are no longer received, and the transfer control circuitry via the transfer relay switches the battery from the lamp to the primary power source for charging.

ystème de vérification d'appareils d'éclairage de secours utilisant un récepteur connecté à l'appareil d'éclairage de secours et un émetteur-récepteur portatif exploitable à distance de l'appareil. L'éclairage de secours comprend un relais qui commute entre une batterie d'une source d'énergie primaire et une lampe. Un bouton TEST et le récepteur comprennent chacun un commutateur contact NF (normalement fermé), ces éléments étant connectés en série entre eux ainsi qu'avec les circuits d'alimentation primaire et de commande de transfert. L'émetteur génère des signaux codés qui sont transmis sans fil au récepteur aussi longtemps qu'un commutateur de commande de l'émetteur est activé par un utilisateur. Le récepteur reçoit et décode les signaux codés et tient ouvert son relais NF aussi longtemps que les signaux codés sont reçus, de sorte que les circuits de commande de transfert activent le relais pour commuter de la batterie de la source d'énergie primaire à la lampe. L'émetteur met fin à l'émission des signaux codés quand l'utilisateur désactive le commutateur de commande. Le récepteur ferme ensuite son relais NF lorsqu'il cesse de recevoir des signaux codés, et les circuits de commande du relais commutent de la batterie de la lampe à la source d'énergie primaire pour chargement.
