The SPL-2030 outdoor alarm is a cost-effective version of the SPL-2010 alarm that does not have an internal can housing to protect the electronics and a foam detector. The SPL-2030-R visual-acoustic outdoor alarm fulfils its function in two ways: visually (red flashing light) and acoustically (volume-modulated acoustic signal). The device has two control inputs that allow the control method to be selected. The design of the alarm ensures a high level of tamper protection against opening and removal from the mounting base. The outer casing of the alarm system is made of impact-resistant polycarbonate, which gives it a very high mechanical resistance and guarantees an aesthetic appearance even after many years of operation.
