This Portable Pager comes with 3 Door/Window Transmitters offering a long range of up to 150 metres, alerting you when a door or window is opened — ideal for home security or keeping track of children, pets or elderly family members who may wander.

The pager offers 4 alerting modes (ringtone, vibration, flashing light, or combinations), including a noiseless vibration mode for night-time use, with 4 ringtones and adjustable volume from 0dB to 110dB. Includes a back-clip case and batteries; more transmitters can be added to the system.
