Viking SRC-1 lets a touch tone phone securely activate a relay contact, which means it can be used to control a doorstrike or a gate controller. This well-built, reliable module is user programmable and has non-volatile memory, so you can customize your door entry system to your liking and it'll stay that way even in the event of a power outage. This relay controller will only act on touch tone signals from the phone you want, and only if the correct activation is dialled.
Viking SRC-1 has memory for 32 entry codes. The codes can be between one and six digits long. Alternately, you can disable the entry code function for even greater security. It can be used in conjunction with compatible Viking door boxes, entry phones, or panel phones, and features a switchable 32V talk battery. A 12V DC adapter is included in the package.
