DA341
24V AC/DC to 12V DC converter, 1 x 350mA output.
This converter is ideal when you have a 24V AC supply at a camera housing for a heater and you require 12V DC to power the camera.

DA290
Battery Low Voltage Isolator (battery disconnect). For use with 12V DC power supplies with standby batteries. Designed to prevent batteries from completely discharging after prolonged mains failure. It is normally fitted into the control or power supply unit or both.
It connects between the battery and power supply and can be used with two batteries in parallel. The relay, which 'drops out' at approximately 9 volts and 'pulls in' at approximately 11.75 volts, is capable of switching 5Amps. A Green LED indicates relay status. ABS Cased.

DA305
A large metal enclosure designed to house either the DA370 or DA380 (3Amp or 6Amp) power supplies. The case has mounting studs to fit either power supply and allows enough room to fit 2 x 24Ah VRLA batteries.
The case is also fitted with an indicator board that provides ‘Mains’ on and ‘Fault’ indication if connected to a DA370 or DA380 power supply.

DA455
IRMA. An active Infra Red Multi-purpose Alarm, designed to detect the presence or absence of a nearby surface. An Infra Red beam is transmitted from the unit and is reflected back by a nearby object or surface (up to 75mm). If the object or surface is removed the beam will not be reflected back and the alarm will operate.
Open or closed circuit working, link selected. Must be used in conjunction with an intruder alarm system. 12V DC operation. ABS Cased. This unit was primarily designed to detect movement of roller shutter doors and has since been used in numerous different applications.

DA314
A range of EOL (End Of Line) resistor packs.
Designed to significantly reduce installation time.
Wires are colour coded for ease of identification during installation. The packs can be produced to customer specification and are supplied in multiples of 8 per pack. Typical values include 1K/1K, 2K2/4K7, and 8K2/8K2.
