User action
Purge gas
Apply gas and calibrate the detector.
Press Continue when the detector has been
calibrated and is providing the correct output signal.
Channel has correctly calibrated.
Input signal was out of acceptable range, re-
calibrate the detector and check that its output
current is proportional to the gas level
Reminds the user to remove the calibration gas and
re-expose the detector to clean air.
Test
Use to simulate
inputs and
outputs for
testing and
commissioning
purposes.

Forces common level 1, 2 or Fault relays.
L1 = Level 1.
L2 = Level 2
The ‘values’ show the current state of each relay
(relays may be normally energised or de-energised
dependant on configuration):
‘No alarm’ or ‘No fault’ means the relay is in its normal
state.
‘In alarm’ or ‘In fault’ means the relay is in its alarm or
fault state.
Use the Up and Down buttons to change the relay
state, press Back to exit, the relay will return to its
normal state
Channel #1, #2, #3, #4
Use the Up and Down buttons to select the desired
channel. The channel warning symbol will show.
Channel alarm relays can be tested as described
above.
Sim Input #1
Values =
0.0 - 25.5 mA
0.0 - 66.7 mA
for fire detectors
Force output #1
Values =
0.0 - 25.5 mA
When selected, displays the input signal level for the
selected channel (e.g. 4.1 mA).
The channel warning symbol will show.
Use the Up and Down buttons to force the input
to the required level. The reading on the channel
display will change accordingly and alarms will
activate at the preset points.
Use the Accept/Reset button to silence alarms if
necessary. Press Back to exit, the input will return to
its normal state.
When selected, displays the analogue output
signal level for the selected channel (e.g. 4.1 mA).
The channel warning symbol
will show. Use the
Up and Down buttons to force the output to the
required level.
