Uploaded by Finn

CentaurTM II Dual 3G alarm signalling equipment monitors up to four fire alarm systems and reports alarm, fault, and isolate information to a control and monitoring station via two radio links. The instructions describe power-up sequences, link status indications, and responses to power, internal fault, and alarm/test conditions. They also cover normal operation cycling through off-normal inputs, key insertion behavior, Isolate and Test modes, daily self-tests, acknowledgements from the CMS, and test-mode timeout and buzzer alerts.

CENTAURTM II DUAL 3G Alarm Signalling Equipment OPERATING INSTRUCTIONS The CentaurTM II Dual 3G ASE is a self-contained alarm signalling device which monitors up to 4 fire alarm systems (either fire detection or sprinkler), and sends alarm, fault and isolation information to a Control and Monitoring Station (CMS) . It communicates through two radio links. Typically the Radio is the primary link and the 2nd Radio is the backup link. Power-Up Sequence and ASE STATUS Indicators On power-up, the ASE will turn all indicators and buzzer on for three seconds, then the POWER indicator will stay on while some internal checks are carried out. After the internal checks have been completed the POWER indicator will turn off and a coded form of the software version number will be displayed on the INPUT indicators for 3 seconds. One of the RADIO, PHONE or ETH/RADIO 2 indicators (the primary link) will then flash rapidly until the ASE has established a connection with the CMS. The outcome of this is shown on the indicator as follows: | Indicator | Status | | --- | --- | | Off | Not used | | Rapid Flashing | Establishing Connection | | Flashing | Link fault | | On | Link O. K. | Any programmed backup link indicators will turn on steady, unless there is a problem with the link. If the POWER indicator is off or flashing, then there is a problem with the power supply for the ASE, or the voltage is too low. If the FAULT indicator is on or flashing, then the ASE is not functioning due to an internal error. Contact your Fire Protection Contractor. If any input is in alarm, the ALARM and TEST MODE LEDs will flash and the buzzer beep for 15 seconds. If a Test key is inserted during this period Test Mode is automatically entered and the alarm is not sent to the CMS. If the ASE is powered up with a key installed, all enabled inputs will automatically be put into Test Mode. It is recommended to always power up an ASE with a key inserted to prevent false alarms. Normal Operation Normal operation of the ASE is shown by the POWER, RADIO and ETH/RADIO 2 indicators being on steady, and no flashing indicators. The INPUT indicators, numbered 1 through 4, correspond to the 4 alarm systems that can be monitored for Alarm, Fault and Isolate conditions, as well as open and short circuit wiring faults. On detecting any off-normal condition the ASE will light the corresponding INPUT indicator and flash the appropriate ALARM, FAULT, ISOLATE or WIRING FAULT indicator(s) until the new condition has been transmitted to and acknowledged by the CMS. Then the indication will turn on steady. When the condition returns to normal, the corresponding indicator will flash until the condition is acknowledged by the CMS, then the indication will clear. If more than one alarm system is off-normal, the ASE will cycle around these, showing each off-normal Input and its status for two seconds. It will take 8 seconds to cycle through if all 4 Inputs are enabled and off-normal. Key Insertion The CentaurTM II ASE uses a key that must be inserted to enable Test Mode. After inserting the key, all enabled inputs are selected (shown by all the INPUT LEDs flashing for 5 seconds); each subsequent press of the Input button will step through each enabled input (shown by the flashing INPUT LED) and back to All. Isolate Mode When the ASE is in Isolate Mode any input conditions sent to the CMS are marked as being Isolated. This stops the CMS acting on them. Isolate Mode cannot be selected at the ASE – only at the CMS. Test Mode When the ASE is in Test Mode any input conditions sent to the CMS are marked as being a Test. This stops the CMS acting on them. The CMS still sends an acknowledgement of the new condition back to the ASE. This allows tested conditions to be checked that they can be successfully received by the CMS. To enter Test Mode insert a valid ASE key and select the input if not all are to be tested. The ASE will cycle around all enabled

FAQs

How does the ASE behave during power-up and link establishment?

On power-up, all indicators and the buzzer turn on for three seconds, then POWER stays on while checks run. After checks, POWER turns off and a software version code is shown. The primary link indicator (RADIO, PHONE, or ETH/RADIO 2) flashes rapidly until a connection to the CMS is established, after which the indicator shows the final link status.

What is the difference between Isolate Mode and Test Mode?

Isolate Mode marks any conditions sent to the CMS as Isolated and prevents the CMS from acting on them; it can only be selected at the CMS. Test Mode marks conditions as Test so the CMS acknowledges them without acting, allowing verification that the CMS receives tested conditions correctly.

What happens when the key is removed during Test Mode?

When the key is removed, the ASE exits Test Mode unless Test Mode times out after 4 hours. If a FAS input is in alarm, the ASE beeps and flashes the TEST MODE LED for 15 seconds, and reinserting the key during that period restarts Test Mode to prevent the alarm being sent to the CMS.
