Description
IMPACT® combination alarm panels shall be designed to
meet the requirements of NFPA and CSA standards.
Alarms shall be UL listed and ULC approved as an
assembly and shall include all necessary displays, factory
wiring, transformers and circuitry, requiring only 115 volt
or 230 VAC primary power. Internal voltage shall be
stepped down to 5 VDC and 15 VDC for control circuit
power. Voltage to external pressure or vacuum transducers
will be 15 VDC. All transducers for combination alarms
shall be installed at the pipeline and wired back to the
alarm panel using 2-wire shielded cable.
Combination alarm panels shall be modular in design and
accept any combination of pressure, vacuum, dual display,
8-transducer, and/or switch input modules.
The control module shall include a Silence/Enter button, a
Test/Shift button, an Up button, and a Down button.
These buttons shall be used to silence the audible alarm,
set up the alarm panel, and to test the alarm panel. The test
button shall test all modules one at a time. An LED on the
control module shall illuminate green to indicate power
on.
Line pressure modules shall be available in single and dual
display configurations. Single display modules shall be
specific to pressure or vacuum, while dual display modules
shall accept any combination of pressure and/or vacuum
inputs. Single display modules shall incorporate a vertical
series of LEDs to indicate relative pressure. Dual display
modules shall include 3 LEDs for each display, indicating
low, normal and high pressure. Display modules shall
automatically alarm at ±20% of standard pressure
(Vacuum and WAGD modules are set up at install.).
8-transducer modules shall each monitor up to eight (8) 420ma transducer inputs. The 4-digit display shall cycle
through the inputs, indicating the pressure, temperature,
current, flow, etc. that is being monitored. LED’s for each
input monitored shall illuminate green for normal status,
red for abnormal/alarm status.
10-signal switch input modules shall each accept up to 10
switch inputs. Inputs shall be for normally closed circuitry,
per NFPA99. LEDs for each input shall illuminate green
for normal status, red for abnormal/alarm status.
The power supply shall be installed in the backbox. Power
supply shall accept either 115 or 230 VAC pimary service,
and shall include an On/Off rocker switch and a fuse
holder.
The audible alarm tone shall pulsate, 90 dBa at 2 meters.
The audible portion of each alarm shall be silenced by
means of the “Silence/Enter” button on the control
module. Activation of additional alarms shall re-initiate
the audible alarm. Regardless of the audible alarm, the
display shall indicate abnormal as long as a fault condition
exists.
The panel shall be equipped with contacts for connection
to the PC-based alarm monitoring software. Alarms that
require installation of additional circuit boards to allow PC
-based monitoring are not acceptable.
Combination alarm panels shall be Chemetron® IMPACT
Series 74-15-XXX.
