Maintenance
No Special Tools Required
All maintenance is achieved from the front of the annunciator without the use of special tools. For
Alarm Card or Supply/Pushbutton/Relay Card replacement or to change the mode of operation, only
the front legend plate needs to be removed.
Legend Plate Removal
The legend plate is easily removed by undoing the associated fixing screws to reveal the plug in Alarm
Cards and Supply/Pushbutton/Relay Card.
Film Legend Engraving
Film legends are accessed from the side of the legend plate and simply slide in place between the two
layers used within the plate.
Alarm Card or SPR Card Removal
In the event of alarm card or SPR card failure or to change feature settings, the associated cards are
easily removed for repair or configuration by simply pulling on the card edge to remove it from the
associated edge connector. Replacement is the reverse of removal, note that care must be exercised
when replacing the board to ensure that the card is properly located into the card guide runners before
firmly pressing the module into the associated edge connector.
•
Alarm Cards are designed to allow insertion and removal with power applied
•
SPR Cards please note due to the high voltages present on the primary supply of the SPR
module it is recommended that the power is isolated before the SPR is removed or inserted.
Super-Bright LED’s
To obtain a virtually maintenance free alarm system the UC625 annunciator is fitted with super-bright
LED’s. These LED’s can be supplied in different colours to suit alarm priorities if notified at time of
order. Colours available are red, amber, yellow, white and green.
Fuse replacement
Each UC625 annunciator can contain a maximum of two fuses.
One is used to protect the signal supply voltage on standard 24VDC versions and Fuse F1 is situated
on the rear of the enclosure in the top right hand corner as detailed below.
The second fuse is located in a surface mount socket on the Supply/Pushbutton/Relay (SPR) Card
and is used to protect the power input on Supply 2 on versions where 24VDC is used as an aux
supply. Replace fuse with a 1A/F surface mount fuse Type 451001
