Built-in Tamper Protection
For added protection, built-in cover tamper switches trigger an alarm whenever the chassis
cover is removed, thus protecting against unauthorized access to the 7720PLUS. The tamper
zone number must be entered during programming to enable tamper reporting. A radio
configured for ECP automatically reports the tamper status to the control panel, as well as to
the central station

Antenna
The 7720PLUS can use either the supplied omni-directional wire antenna, or can use a 7825
outdoor antenna, 7625 omni-directional antenna, 7625-3DB antenna (if additional gain is
required), or a 7674 (if a directional antenna is required), by using the optional 7720ANT
connector kit. For wall mounting, an optional 7825DP can be used. The supplied antenna
mounts directly to the7720PLUS. The antennas (other than the wire and the dipole) can be
mounted remotely using the following pre-assembled coaxial cable available from ADEMCO:
5ft coax (P/N 7626-5), 12ft coax (P/N 7626-12), 25ft coax (P/N 7626-25HC), and 50ft coax (P/N
7626-50HC).
