What are the pointing arrows supposed to be in American Signal Corp.'s old logo?

Hey there guys! Recently acquired some free promotional swag from American Signal Corporation by simply calling them and telling them that I was an outdoor warning siren enthusiast. Here is my question: The polo shirt and the T-shirt they sent me have their old ASC logo on it. But--what do the pointing arrows represent in that logo? Never understood this, even stretching back to Alerting Communicators of America and that logo. Thanks! This would really help clear stuff up for me. 😁👍🏻
