TIR4 Infra Red Pendant Trigger.
The infra red trigger is worn by residents and allows access to the call system at all times. It will trigger any Intercall
700 series call point within range and can be configured to generate different levels of call. Each trigger is assigned a
unique number which may be programmed into the system to identify the calling resident by name. All Intercall 700
series call points are fitted with infra red receivers as standard and one call point will typically cover a room area of
20sq metres. For information on the positioning of infra red call points please refer to page.
The battery life in the trigger depends on frequency of use and in a typical TIR4 installation expected life is between 6
and 12 months. The battery is a 12volt battery type 23A Alkaline which is available from many retail stores.
