INTRODUCTION
The 5701 Series Control System is equipped to provide the operational
and engineering facilities necessary to fully maintain a system of gas
detection equipment.
Each control card within a rack system displays a sensor reading, alarm
status and condition of that channel.
Further information can be gathered and, depending on the security
status, certain settings can be adjusted by means of an Engineering
Card fitted to the rack.
The relay outputs of the system are configured to provide a range of
output alarm functions as follows:
a. Fault Alarm
The fault alarm activates when a fault is detected in the control card
or associated sensor and is not user configurable. In addition the
FAULT LED will be illuminated.
b. Inhibit Alarm
The inhibit alarm activates when the system alarms are inhibited for
any reason and is not user configurable. In addition the INHIBIT LED
will be illuminated.
c. A1, A2 and A3 Level Alarms
The A1, A2 and A3 level alarms are activated when the level of gas
being measured crosses the preconfigured alarm threshold. In addition
the relevant LED will be illuminated.
d. STEL Alarm (Short Term Exposure Limit)
The STEL alarm will be activated when the time weighted average
concentration of a toxic gas, usually averaged over 10, 15 or 30
minutes, crosses a preconfigured threshold. When active STEL will
be shown on the message display of the control card. For certain
relay cards and configurations, the alarm LED associated during
setup to the STEL alarm will be illuminated.e. LTEL Alarm (Long Term Exposure Limit).
The LTEL alarm will be activated when the time weighted average
concentration of a toxic gas, usually averaged over 8 hours, crosses
a preconfigured threshold. When active LTEL will be shown on the
message display of the control card. For certain relay cards and
configurations, the alarm LED associated during setup to the LTEL
alarm will be illuminated.
f. Rate Alarm (Version 2Vx Software only)
The rate alarm predicts the future gas concentration by monitoring the
rate of rise of the sensor signal and provides an early alarm indication
before the sensor signal reaches the next level alarm set point.
g. Individual Alarm
An individual alarm is caused by the input to an individual control
channel crossing a preconfigured threshold and is not related to any
other control channel. The relevant LED (A1, A2, A3, Fault, Inhibit) will
illuminate on the control card with the alarm condition.
