Wireless Devices - EMS FireCell Programming Manual

Wireless Devices

The wireless devices have LED indicators and log on buttons which perform certain functions. This
section explains their functionality.
Log On Button; the Log On button is used for adding devices to the system. The required procedure for
achieving this is detailed within the 'Quick System Programming' section of this manual. The action of
pressing the log on button for 2 seconds will revert the device to its commissioning frequency channels
to allow addition to the system, and also illuminate the log on LED.
NOTE: Care should be taken not to press this button when the unit is already added to the system and
operating on its allocated frequencies as this frequency information will be lost and default to the
devices commissioning channels.
Log On LED; the LED is allocated next to the Log On button on the detector and sounder. This will
illuminate when the log on button has been pressed for two seconds. On a call point the Alarm LED on
the front of the device is utilised as indication that the Log On button has been pressed for 2 seconds.
Alarm LED; the Alarm LED will switch on in the event of an alarm condition detected by the device. The
device controls this indication for the rst 10 seconds of the alarm condition. After the initial 10 seconds
the LED indication is completely controlled by the connected Fire Alarm Control panel and will therefore
turn on and o as instructed to do so by the programming in the panel.
Audio Detect Enable Switch; an audio detect switch is located on the sounder base. This feature can be
enabled for each of the sounder output stages 1 or 2 using the corresponding number on the 2 way
switch. When enabled the unit carries out tests when operated, by checking the actual sound output. If
no sound is detected within 10 seconds of the sounder base being switched on a fault will be indicated
at the control panel. This feature should be disabled for a beacon only unit (Switch 1 and 2 o ).
Output LED; an Input/output device has a red LED associated with each relay output. If the LED enable
button is pressed and the output is activated the LED will illuminate. The LED's will be illuminated for 10
minutes and then automatically time out.
Input Fault; an Input/output device has a yellow fault LED associated with each input. If the LED enable
button is pressed and the input is in a fault condition the LED will be illuminated. The LEDs will be
illuminated for 10 minutes and then automatically time out.
Input Switch Closed; an Input/Output device has a red switch closed LED associated with each input. If
the LED enable button is pressed and the input is closed the LED will be illuminated. The LEDs will be
illuminated for 10 minutes and then automatically time out.
