Napco Security Technologies Inc. announced the Napco StarLink Future-Proof Universal Radio Series – SLE-GSM3/4G model 3G/4G Network-Ready Radio. The Napco SLE-GSM Series features an upgradeable communication module so it can be upgraded anytime there are progressions in cell networks from 2G to 5G to xxG, down the road, without ever replacing the radio. Like its predecessor, the StarLink 3 (Model: SLE-GSM3/4G) still features universal full primary or backup event reporting from any panel brand to any central station and requires no special equipment. Email, text, or SMS messages alerts are a selectable option (SLe-SMS service). One-step enrollment and programming is built in. Advanced programming options are also available. A takeover feature easily captures any panel’s existing central station phone number and allows you to reroute it to another central station.
