The paging adapter(s) shall be Alpha
Communications® / S.T.R.™ model DV4, or
approved equal. Amplifier shall operate from a
16VAC (40VA) U.L. Listed transformer (model

voltage Class II wiring, installed as per all
federal, state, and local electrical codes. Paging
adapter shall surface mount right to the finished
wall and shall be installed in a
suitable environment that is free from excessive
dirt, dust, temperature, humidity, grease and
water. For most secure installation, unit should
be installed into a lockable equipment cabinet /
housing. Unit shall be installed adjacent to the
NH908A or NH208TVU amplifier, a safe distance
from any source of electrical interference. The
DV4 shall provide 10 watts of audio power,
distributed to four (4) independent zones, and
have an 'ALL-CALL' capability. Where required,

DV4 4-Zone Paging Adapter/Amplifier
The Alpha Communications® / S.T.R.™ DV4 4-zone paging adapters are used with
the S.T.R.™ HT2006 series handsets when one (1) to four (4) zones of paging is
required. The DV4 has a built-in 10 watt audio amplifier, and can provide that power
up to four (4) zones. Each zone can be paged from a different selective button on
the HT2006 handset, and you can make a 5th button an 'ALL-CALL' button, which will
activate all four (4) paging zones simultaneously. The DV4 has no music-muting
capabilities built-in. If background music that will mute when a page takes place is
required, you must provide a separate p.a. amplifier/tuner set-up with an amplifier
that has auto-muting capabilities. If more power is required than 10 watts you can
feed the output(s) from the DV4 into one or more higher powered paging amplifiers.
The DV4 operates on 16VAC (40VA) low-voltage Class II wiring. Each DV4 requires a
separate Model T1640 (U.L. Listed) plug-in transformer. Do not power from the
same transformer that is providing power for the intercom amplifier.
These DV4 paging adapters are designed to easily surface mount right onto the
finished wall by means of customer supplied screws or the convenient plastic 'Din
Rail' bracket supplied with each unit. Connections are positive screw terminal type.
The DV4 must be used in addition to the NH908A or NH208TVU intercom amplifier.
