5. Wiring Instructions

•  When alarms are interconnected, all interconnected units must be 

powered from a single circuit.

•  A maximum of 18 

Garland

 

OnGard 

safety devices may be 

interconnected in a multiple station arrangement. The interconnect 

system should not exceed the interconnect limit of 12 smoke alarms 

and/or 18 alarms total (smoke, heat detector, etc.). 

(see below for details on interconnecting 

Garland OnGard

 devices).

•  The maximum wire run distance between the first and last unit 

in an interconnected system is 307 meters. 

Figure 3

 illustrates 

interconnection wiring. Improper connection will result in damage to 

the alarm, failure to operate, or electrical shock hazard. 

•  Make certain alarms are wired to a continuous (non-switched) final 

sub-circuit.

Note: Use approved listed Australian Standards cable 1.0mm² 

TPS or larger as required by local codes.
