*Pairs of input lines required to supply Operating Voltage
or Voltages to the unit. Pairs listed do not include signal wires to Alarm panels
not control wires to other units' solenoids.
Operating Voltage or Voltages for the control of fire/smoke
doors are specified by the architect, electrical engineer and alarm system engineer and
/or contractor. Consulting with these sources will verify which operating voltage(s)
should be ordered.
"PTD" Master Units have two
components which require electrical power; the Integral Smoke Detector will always require
24VDC input power; the Hold-Open Solenoid can require either 24VDC input or 120VDC input.
A third component, the hook-up box, receives all primary voltage inputs and distributes
them to the smoke detector and the hold open solenoid.
"PTD" Master Units are available
with three voltage options:
With PTD-24 suffix - unit will accept either 24VAC or 24VDC
power input,. A rectifier in the hook-up box will rectify alternating current to direct
current for operation of both the smoke dete4ctor and hold-open solenoid.
With PTD-120 suffix - Unit will accept 120VAC power input.
A 120VAC to 24VAC transformer in the hook-up box steps the input voltage down to 24VAC. It
is then rectified to 24VDC for operation of both the smoke detector and the hold-open
solenoid.
"PTD" Master Units Voltage Options (cont.)
With PTD-24D x 120 suffix - Unit must
receive 24VAC or 24VDC power input . A rectifier in the hook-up box will rectify
alternating current to direct current for operation of the smoke detector. Unit
must also receive a 120VAC power input from a separate circuit. It is then
rectified in the hook-up box to 120VDC to operate the hold-open solenoid.
Slave Units (PTS suffix) have only a
hold-open solenoid which requires electrical power. They are only available with an
operating voltage of 24VDC since they are only installed when they are controlled directly
by the integral Smoke Detector of the Master Unit.
Support Units (PT-24 or PT-120 suffix)
similarly have only a hold-open solenoid which requires electrical power. These solenoids
are controlled by Smoke Detection Equipment or remote Alarm Panels. They can be ordered
for operation on 24 Volt AC/DC or 120VAC, 60Hz. Support units (PT-24 or PT-120
suffixes) have their hold-open solenoid operating on direct current. They have
built -in rectifier that converts alternating current to direct current. |
