The Series 65 Heat Detector monitors temperature by using a dual thermistor network The heat detector classes available in Series 65 are A1R, BR, CR, CS. The Series 65 Ionisation Smoke Detector uses a low activity radioactive foil to. The Series 65 Diode Base is designed for use with conventional systems that.

Despite our best efforts, mistakes sometimes happen. When the sum of the resistance of the insulated thermistor and the fixed resistor compared to the resistance of the exposed thermistor reaches a preset value, an alarm is initiated. The supply may fall to 6 volts DC in alarm conditions if a supply current of at least 10mA is available at this voltage.
The radioactive source holder and apoollo chamber form positive and negative electrodes respectively. Any orders received under the minimum order value will be returned to sender for revision. Hi Lauren, The below parts have just arrived!
Series 65 A1R Heat Detector
To restore the detector to quiescent condition, it is necessary to restore a normal temperature level and interrupt the electrical supply to the detector for a minimum of one second.
There are 12 heat detectors in the Series 65 range designed to suit a wide variety of operating conditions. Back Series 65 Diode E65 Product code: All Series 65 bases have a one-way appllo fit. Storage regulations depend on local standards and legislation, but, in the UK, the number of ionisation smoke detectors in any building or premises shall be less than Please note… Remember to quote your account number and purchase order number on any order correspondence.

The Series 65 range has a wide operating voltage of 9—33V and consists of ionisation, integrating ionisation and optical smoke detectors, four grades of heat detector and a range of bases. Full details of our service standards can be downloaded here. If the resulting signal from the photo-diode is above a preset threshold, the LED emits two more bursts of light, this time at two-second intervals. This fall in the impedance of the detector is recognised by the control panel as an alarm signal.
If air temperature increases slowly, no significant resistance difference develops between the thermistors, but at high temperatures a fixed value resistance connected in series with the insulated thermistor becomes significant.
APO – Series 65 CS Heat Detector
A remote indicator connected between the L1 IN terminal and the —R terminal will have a voltage equal to the supply voltage less 1 volt across it and so will illuminate. Hi Emma, Thank you for your awesome work!
The value of the fixed resistor is selected to set the detector into alarm state at a specified fixed temperature. Each heat detector classification has a static response changing to alarm at a preset temperature and may also have a rate of rise response changing to alarm at or above a preset increase of temperature.
This includes making our order, service and delivery process a seamless and hassle-free experience. The bases are of mm diameter and have five terminals marked according to their function: Nickel plated stainless steel wiper contacts connect the detector to the base. The external detector moulding is identical to that of the ionisation detector but has an indicator LED which is clear in quiescent state but produces a red light in alarm.
Apply to standard and integrating versions 1.
The Series 65 Heat Detector monitors temperature by using a dual thermistor network which provides a voltage output proportional to the external air temperature. To ensure correct operation of the detector the control panel must be arranged to supply a maximum of 33 volts DC and a minimum of 9 volts DC in normal operation. apolo

Oops… Despite our best efforts, mistakes sometimes happen. Detector locking mechanism One-way fit Easy to wire Contains an earth connector Contains no electrical parts Terminal for remote indicator.
To restore the detector to quiescent condition, it is necessary to restore a normal temperature level and interrupt the electrical supply to the detector for a65 minimum of one second.
