Emizon TCD
Step 6 - Testing
Following successful activation, test all alarms on both signalling paths. (First send a
set of alarms, then disconnect the Ethernet cable, forcing alarms over the GPRS
path. NB: The Ethernet LED will start flashing to indicate failure mode). Remember to
reconnect Ethernet connection when testing complete. Testing complete, affix the
antenna in place on top of the panel. For Reporting times please refer to Emizon
Section of the Installzer Zone.
THE TCD MUST BE COMMISSIONED WITH BOTH PATHS FULLY ACTIVATED BEFORE LEAVING
SITE. THE MINIMUM RECOMMENDED GPRS SIGNAL STRENGTH IS 12, THE MAXIMUM IS 31. TO
SEND A TEST SIGNAL TO THE ARC ON BOTH PATHS, PRESS THE SET BUTTON SW401 FOR 5
SECONDS.
You can improve signal strength by purchsing a CSL HGA (High Gain Antenna) with a
5M lead & fitted connector.
POSITING HGA
The HGA must not be fitted right next to the alarm panel, likewise the 5M of cable
must not be coiled up and placed inside the panel as this will not improve the signal
strength. Instead utilize the 5M of cable by placing the HGA in a higher position than
the alarm panel (loft space) to maximise the chance of a better signal strength. It is
also advised to fit the HGA away from any Conduit, Electrical cable etc. If fitting the
HGA inside a roof space, be aware that in modern buildings the insulation bats may
have foil fitted. Where the site has a metal clad roof it is advisable to fit the HGA
externally and high as possible and away from the Panel and in free space. When
securing the HGA to a wall please ensure you use the bracket provided. Thi ensures
that the HGA is at the required distance from the wall.
CONNECTING HGA
Prior to connecting the HGA to the TCD the power must be removed from the TCD.
Connect the MMCX male connector to the TCD and apply power to the TCD. On the
power up wait for T1 01 on the display. LED 101 on the small GPRS PCB should flash
every 2 seconds.
TAKING A SIGNAL STRENGTH
Check the signal strength with a signal tap of the left hand button SW402, then read
the GS, GA and GR values on the display. The values will be display for 1 minute. The
minimum signal strength is GS 12 and the maximum signal strength is GS 31. Do
not press the left hand button SW402 repeatedly. An example of a good signal
strength reading is GS 24 - GA , 05 GR - 05
