Specifications

x Do not define the zone as 24hr. It is recommended to register the GB843
to a perimeter arming group that arms the perimeter doors and windows of
the premises.
x Avoid humid rooms – the GB843 is not hermetically sealed. Excess
moisture can eventually cause a short and a false alarm.
Areas to avoid:
x Glass airlocks and
glass vestibule areas
x Stairwells
x Small bathrooms
x Noisy kitchens
x Other small
acoustically live
rooms
x Residential car
garages
x Small utility rooms
For glass break protection in such applications, use shock sensors on the windows or
window frames connected to an US832 universal transmitter.

1. Open the housing using a small flat-head screwdriver to separate the
base from the cover.

few seconds. You can terminate Test mode by closing the Tamper
switch. Test mode is automatically terminated after approximately five
minutes.

display, press 3.
5. After registration, press the GB843’s tamper switch to terminate Test
mode.
