Sequence of Operation
1. Sensors are pre-loaded with options for normal operation and can be changed by the user at any time via the key pad.
2. On power-up the display will show the software revision number and the Warm-Up Timer will count down (setting 52, default 1
minute). Relays are inactive during this time. Press any button to cancel the warm-up period.
3. The display will show the gas type and the current gas concentration. For dual-sensors the display will alternate between the two
sensor modules and show the gas type and concentration of each. If the network display option is turned on (option 56)
the display will show each sensor that is connected via the CAN network, its address, gas type and concentration. Detector will
display for 3 seconds and then cycle to the next, lowest address to the highest and then start again.
4. If the gas level rises above the Level One Set Point then the Delay- On Timer will start. The time setting range is from 1 to 999 seconds.
If the gas level drops below level one the timer will reset and start over the next time it goes over.
5. If the gas level stays above the Alarm 1 Level for the set time the relay 1 on-board will energize, and remain energized as long as
the gas remains above the alarm setting. The bottom left corner of the display will indicate a 1 and the alann 1 LED will light up. In
addition, the Alarm 1 Transmit Message (default is 1) will be sent to all detectors and controllers via the CAN network.
6. All sensors or controllers on the CAN network with a Relay 1 Receive Message (setting 36) = 1 will energize their on-board relay 1,
and display a 1 in the bottom left hand corner of their display.
7. When the current gas concentration drops below the Alarm 1 set point, the Delay-Off time will start. The timer will clear if the gas rises
above the alarm setting.
8. When the Delay-Off Timer times out the relay 1 will de-energize, the Alarm 1 LED will turn off and the Relay 1 Transmit message will
stop being sent, thereby de-energizing relays on other units.
9. If the temperature exceeds the Hi Temperature Alarm, setting 51, relay 1 will activate, the Alarm 1 LED will turn on and the Alarm 1
Transmit message will be sent via the CAN network to other sensors and controllers. When temperature drops one degree, the alarm
1 will be turned off and the Alarm 1 Transmit message will stop being sent.
10. If the gas level rises to the Alarm Level 2 setting, then the Level 2, Delay-On Timer will begin, and after timing-out the on-board relay
2 will activate (for models 60xx-B only) the Alarm 2 LED will tum on, the Relay 2 Transmit message (default = 2) will be sent out on
the CAN network activating remote units with that same Relay 2 Receive message (option 37).
11. When the current gas concentration drops below the Alarm 2 setting, for longer than the Alarm 2 Off-Delay Setting the relay 2 will
turn off, the Relay 2 LED will turn off, and the Relay 2 Transmit message will stop being sent on the CAN network.
12. When the gas concentration rises above the Alarm Level 3 setting, for more than the Alarm 3 Delay-On timer the audible alarm will
sound, the LED strobe flasher will start Qf (If enabled, setting 45), a 3 will appear in the bottom left corner of the display, and the
Alarm 3 Transmit message (default 3) will be sent to other sensors or controllers. They can be silenced by pressing any button.
13. When the gas concentration drops below the Alarm 3 set point for longer than the Alarm 3 Delay-Off setting then the audible alarm
and strobe flasher will stop and the Alarm 3 Transmit message will stop being sent on the CAN network.
14. On a sensor fault condition, the units will transmit the Fault Transmit Message, option 59, to other sensors or controllers.
15. A Manual Over-ride mode is available to test relay functions and to activate ventilation. From the home screen press and hold the up
arrow for 5 seconds. Press the up arrow to increase the timer by 5 minutes per click up to 60 minutes. The screen will display MAN
5 and timer will energize relay 1 and send the Alarm 1 Transmit Message on the CAN network. After the time runs down the unit
will return to automatic operation. To cancel, press the down arrow several times to reduce the timer to zero and return to normal
operation. To activate alarm, Level 2 or 3 as well with this procedure, set option 69 to 2 or 3.
