PGST infrared sensor: passive infrared detection
The PGST PIR (Passive Infrared) sensor detects heat variations emitted by moving bodies within its detection zone. When a presence is identified, a wireless signal is immediately sent to the PGST alarm panel, which activates the siren and sends notifications to programmed emergency contacts.
Passive infrared technology ensures high reliability with minimal false alarms caused by light changes or air currents. For optimal coverage, install the sensor in a corner at height, angled to cover the main traffic areas of the room.
PGST infrared sensor: installation
Mount the PIR sensor in a corner of the room at a height of approximately 1.8 to 2.4 m, oriented towards the main access areas (doorways, corridors, stairs). Avoid pointing it towards direct heat sources such as radiators or sun-exposed windows, which could generate false alerts.
Wireless and battery-powered, installation requires no wiring. Perform a range test before finalising the position to ensure reliable signal reception by the PGST panel.
PGST infrared sensor: pet immunity
If you have pets, some PGST PIR models are available in a Pet Immune version that ignores the heat signature of small animals while still detecting human-sized movement. This prevents false alarms from cats or small dogs moving around the house at night.
5 key takeaways about the PGST infrared sensor
- Passive infrared detection: detects heat variations from human movement, reliable and accurate.
- Wireless: radio communication with the PGST panel, no wiring needed.
- Low false alarm rate: PIR technology unaffected by light changes or air currents.
- Pet Immune option: available in a version that ignores small pets.
- Long battery life: ultra-low standby consumption with level reporting to the panel.
FAQ — PGST infrared sensor
Does the PGST PIR sensor work in the dark?
Yes. The PIR sensor detects infrared heat, not visible light. It is equally effective in complete darkness and in daylight, with no need for additional lighting.
How many infrared sensors can I connect to a PGST panel?
The number of sensors you can connect depends on your PGST panel model (PG103, PG106, PG107, or PG108). Refer to your panel’s specifications for the maximum number of supported zones.
What is the difference between a standard PIR and a Pet Immune PIR?
A standard PIR detects any movement producing a human-sized heat signature. A Pet Immune PIR is calibrated to ignore heat sources from small animals, significantly reducing false alarms in homes with pets.
Can I use the PIR sensor outdoors?
The PGST PIR sensor is designed for indoor use. For outdoor detection, use a compatible outdoor camera with motion detection from the PGST range.
Also in the PGST range
Combine the infrared sensor with the PGST door sensor for full perimeter protection. Connect to the PGST PG103 alarm panel. Add the PGST SOS button for manual emergency alerts.
