Safety Information:
Sealed Lead Acid batteries contain sulphuric acid which can cause burns if exposed to
the skin. The low internal resistance of these batteries mean large currents will flow
if they are accidentally short-circuited causing burns and a risk of fire.
Exercise caution when handling batteries.
Power Up Procedure:
Always apply mains power before connecting batteries. When connecting batteries,
always connect the Positive (Red +) terminal first.
Power Down Procedure
Disconnect the batteries before removing the mains power. When disconnecting
batteries, always remove the Negative (Black
–
) terminal first.

Outstation Connections
The HC-228S Master Station is equipped with at least one number Dual line card. One outstation per
line output can be connected. If no outstation is connected to the line output, then an en
d of line 10kΩ
resistor should be fitted. The dipswitch located on the rear of the door mounted Display PCB is used for
configuration see 6.1
The following devices are available on the system:
●
Type A (fixed phone)
●
Type B (hands-free refuge point)
●
Type C “Combi” (combined Type A and Type B)
●
Jack point
●
“Assist Call” emergency assistance alarm system
For Type A, and Type C outstations the end-of-
line 10kΩ resistor is not required as it is integral to the
product. For Type B outstations the end-of-
line 10kΩ r
esistor should be removed from the accessory
pack and connected to the end-of-line terminal in the outstation.
For Jack points and the “Assist Call” system, the end
-of-
line 10kΩ resistor should also be removed from
the accessory pack and connected to the last plate on the system.
