Apollo has introduced an integrated base sounder to its range of loop-powered sounder products. By combining a detector mounting base and sounder in a single moulded unit, the new device is said to simplify and speed up installation.
The unit offers two tone ranges – the low range of 55-75 dB is designed, for example, to warn staff in hospitals and nursing homes. The high range of 75-91 dB complies with EN54-3 requirements for fire detection and alarm systems, and is for general use. Other features include individual or group addressing, as well as synchronisation of alert and evacuate tones where multiple devices are used.
The device also has an acoustic self-testing facility for installation, commissioning or maintenance procedures. It checks itself and if no sound is heard within five seconds, it will transmit a sounder fault when next polled. It is supplied with an integral isolator as standard and a version without one is also available.
