{"product_id":"bogen-var1-voice-activated-relay-for-70v-paging-systems","title":"Bogen VAR1 Voice Activated Relay for 70V Paging Systems","description":"The Bogen VAR1 Voice Activated Relay is a relay device that monitors audio activity over a wide range of input voltages and operates two sets of C-Form relay contacts in response to detected activity. The VAR1 can be used to detect voltages as low as signals directly from a microphone or as high as signals from 70V speaker systems. A low-level output of the detected audio, transformer-isolated from the input, is also made available for use with other equipment. The VAR1 can also be used as a balanced, low-impedance microphone pre-amp. The VAR1 is ideally suited to provide a set of contact closures for paging ports of lower cost telephone systems that do not have a set of AUX contacts to trigger paging equipment. An adjustable release delay (up to 25 seconds) keeps the paging system from dropping out in the middle of a page.\n\nBogen VAR1 Voice Activated Relay Main Features\n\u003cul\u003e\n  \u003cli\u003eTwo sets of C-Form (both N.O. and N.C.) relay contacts respond to audio activity\u003c\/li\u003e\n  \u003cli\u003e4 levels of input signals: microphone, 600-Ohms line, 25V, and 70V speaker systems\u003c\/li\u003e\n  \u003cli\u003eBuilt-in balanced, low noise, high gain microphone pre-A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bogen","offers":[{"title":"Default Title","offer_id":43250889752641,"sku":"BO-VAR1","price":156.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/2465\/9009\/files\/f3c6e5a0-1011664213_lg.jpg?v=1775081000","url":"https:\/\/www.fireandsafetyplus.com\/products\/bogen-var1-voice-activated-relay-for-70v-paging-systems","provider":"Fire and Safety Plus","version":"1.0","type":"link"}
