The DIN-Rail Sounder Controller (5 Amperes) is used to control the operation  of a zone of externally powered sounders and report their status to the control panel.

The DIN-rail Sounder Controller is loop powered and operates at 17–28V DC. It requires a local power supply of 12–35V DC to power the external load, which may be up to 5A. A pol arising diode is required with each alarm device, as sounders are operated by voltage reversal, provided by a double-pole change-over relay. The sounder circuit is protected by a fuse rated at 5A (quick acting).

The DIN-Rail Dual Isolator provides two independent isolators  which sense and isolate short circuits on Discovery and XP95 loops and spurs.

Under normal operating conditions, a low impedance is present between the two negative terminals of each isolator channel so that power and signals are passed to the next base in line.

If a short-circuit or abnormally low impedance occurs across the loop, the fall in voltage is sensed and the isolator isolates the negative supply in the direction of the fault. In this condition, the yellow LED of the affected channel will be illuminated. the isolated section of loop is tested using a current pulse every five seconds. When the short-circuit is removed, the power will automatically be restored.

Gent 704952 Yellow Fascia for Key Switch MCP (For Use with S4-34807)

Gent by Honeywell’s S-Quad Beam Sensors provides an enhanced solution for linear beam detection for applications where point detection is either not practical or economic.

Powered and controlled via the loop, the beam is a market leading device with features such as ‘one man alignment and commissioning’ which is achieved using the auto gain setting, this ensure the optimum alignment is reached.

Maintenance of the beam is enhanced with a key operated test feature which simulates the obscuration of the beam in a fire. The Gent loop powered beam is certified to EN54 parts 12 and 17.
