The SENTINEL General Purpose (GP) Transmitter for use with Ancillary Equipment

The RSS General Purpose Transmitter is used for many applications where an alarm status is required to be sent to the Sentinel PRO 6 radio receiver, either directly, or via a RSS Relay. The items below mostly relate to the HP (high power) version of the GP transmitter.

Because the transmitter is cabled to a detection/monitoring device, it can be mounted some distance from the device at the highest point available (you need to tell us what cable length is required). This can give the transmitter an impressive radio range to the radio receiver and if a Unity Gain Dipole Antenna is connect to the transmitter a range in excess of 2000 metres may be possible (subject to topography).

It may be that you currently have equipment that you would like to monitor. If it has a trigger, then you can integrate an RSS GP Transmitter. Talk to our technical department for advice.

  • The transmitter has contacts for either N/O or N/C circuits.
  • It can be powered either by a 12V DC supply, or by a PP3 9V DC battery.
  • There are connections for a tamper loop.
  • The unit has a Box Tamper. On removing the lid, it will go into alarm.
  • It is fully weatherproof.
  • Robust construction.
  • In most cases, several detection/monitoring devices can be wired to one Transmitter.

Please note: Subject to your requirements, there may be some variations to the above specification.

Nearly every application where a RSS GP Transmitter is used is different. We build to your specification, and, as such, prices vary. Please contact our offices for prices of pre-wired and ready-to-use equipment.
