VPCS-2GPB-2
VPCS-3GPB-245
superior intelligibility for one or two-way communication in high-security
applications. Units are designed for installation in detention, correctional,
and institutional facilities. VPCS intercom stations are also ideal for use
in high-risk public-access spaces such as hallways, lobbies, and parking
garages. Units withstand abuse, moisture, corrosion, dust, vibration, and
temperature extremes from -10˚ to 150˚ F.
General Description
Stations are equipped with a 21⁄2" (64mm) diameter loudspeaker to deliver
clear voice and signal transmission while the phenolic resin impregnated,
moisture-proof cloth cone provides durable performance. The VPCS Series
includes two die-cast baffles to protect the loudspeaker assembly from
vandalism. The Series is available with a 25V transformer providing
and 2 watt taps or as a 45Ω configuration.
Model numbers indicating "PB" include a vandal-proof push-button
call switch for installation where call origination is a required function
or a desired adjunct to security. "PB" models feature a heavy-duty,
momentary action push-button with a 3A at 120VAC/1.5A at 250VAC
contact rating, mounted to an 11-gauge stainless steel face plate. The
face plate mounts standard 2 &/or 3-gang E.O. boxes with any counter
sunk 6-32" mounting screw. Lead wires are 5" (127mm). Switch is single
pole, single throw, normally open. Pushbutton assembly is constructed
of nickel plated brass and sealed against moisture with a classification
of IP65.
VPB-1A is a vandal-resistant pushswitch intercom accessory mounted to
a single gang size stainless steel plate. Utilize assembly in conjunction
with VPCS 2- and 3-gang stations or as a stand alone signaling device
when a separate or remotely located call origination button is desired.
