The Quick-Check PowerSaver Manifold key features include the following:
- Programmable Logic Controller (PLC) with HMI
- Dry Contact Alarm Relay
- Pre-Filter
- O
2
Analyzer
- Gas Input Solenoid Valves on a Manifold
- Exhaust Valve
- 110-220VAC to 24VDC power converter
Programmable Logic Controller (PLC) with HMI
The device is setup with a 24 VDC power converter that will accept either 110 or 220 VAC power supply. The PLC has
a built in 10.1” color touchscreen with 1MB of logic memory, 3MB for images, and 512K bytes for fonts. It has a logic
application scan time of 15 microseconds per 1Kbytes of application code.
Dry Contact Alarm Relay
Each Quick-Check PowerSaver Manifold features a dry contact to send an alarm signal to the Building Management
System (BMS). If the purity status goes above the allowable percent of O
2
or if the flow sensor is not receiving a signal
on any one zone or more, then the alarm on the unit will trip and engage the Dry Contact Relay.
Pre-Filter
The Pre-Filter consists of a filter bowl and particulate filter element with a 5 microns rating that will catch any particles
coming from the fire system pipes and protect the O
2
sensor. The filter features an auto-drain that can be plumbed
to a safe location. The pre-filter is used to remove harmful contaminates in the gas streams that may reduce the life
of the O
2
cell. Based on the quality of gas going through the filter, the filter may be required to be changed out more
often than the factory recommended replacement date.
O
2
Analyzer
The O
2
Analyzer is used to detect the O
2
content of each Zone. It is a galvanic cell type that implements a weak acid
electrolyte and is unaffected by CO
2
, CO, and NOx. It has a response time of 25 seconds or less and will respond to a
90% step change in Oxygen concentration within 15 seconds or better. The output from the O
2
sensor is a 10mV to
15.5mV signal that is sent to the PLC. The signal from the O
2
sensor is digitized on the PLC by a 10-bit analog to
digital converter and calibrated to known O
2
calibrated sources.
