Safety Warnings and Operating Conditions
Qualified Personnel Only
Only qualified service personnel should install, and perform subsequent maintenance on the
Redcare Secure Unit.
Battery Handling
Take care not to short the battery in the host alarm system. A short-circuited battery can deliver
large currents that could result in serious burns or create a fire hazard. Dispose of used batteries
according to local environmental regulations.
Power Requirements
Voltage:
9VDC to 30VDC *
Current: @ 13.8V:
Pin only mode 230mA quiescent, 280mA peak alarm transmission.
Dial capture mode (SIA / CID / FF) 270mA quiescent, 450mA peak alarm transmission.
Current: @ 24V = 170mA
Ripple/noise: 200mVpp max.
Low battery threshold: 10.2V +/- 0.5V.
* The Secure unit can be used with 24V volt systems, i.e. Fire Alarm panels, but be aware
that the low voltage threshold alarm is fixed at 10.2V.
Pin Alarm Inputs
Logic High = +3.5V to +30V
Logic Low = -0.5V to +0.8V
General Purpose Outputs: (on J1400)
Logic High = 12V (nominal) @ 1mA max
Logic Low = 0.4V @ 200mA max
These voltages are with respect to the 0V terminal on the Power Connector J800.
Physical Dimensions
Size = 168 x 115 x 36 mm
Mass = 500 g
