XP95 Intrinsically Safe (IS) detectors are a development of the well established analogue addressable XP95 range from Apollo. XP95 IS detectors feature all the benefits of the standard range, but are developed specifically for use in hazardous areas.
The XP95 IS Manual Call Point is loop powered and operates at 14-22V DC.
The address of each call point is set at the commissioning stage by means of a seven-segment DIL switch.
A red alarm LED is provided on the call point. This LED is controlled independently of the call point, by the control panel.
This Manual Call Point helps reduce installation time as all the initial installation cabling is wired to a terminal block which fits neatly in the back of the Call Point.
Once activated, the XP95 IS Manual Call Point can be reset by inserting the test key into the bottom of the unit until the key clicks into position. Remove the test key and push the front cover up until it clicks home
Operating temperatures (ambient):
-20°C to +70°C
-20°C to +45°C (T5)
-20°C to +60°C (T4)
Additional Information 1
The protocol translator (part no. 55000-855 single channel, 55000-856 dual channel). ensures that the call point operates correctly while itself remaining transparent to the control panel.
The XP95® IS Manual Call Point has been designed to operate on a loop of intelligent fire detection devices and when activated interrupts the polling cycle for a very fast response.
When activated, the intrinsically safe call point not only interrupts the polling cycle to indicate to the control panel that it has been operated, but also reports its address. Thus an alarm and its location can be reported in less than 0.2 seconds.
Full details of the principles of operation and the electrical description are published in the XP95 Engineering Product Guide. XP95 IS manual call points have the same operating characteristics as the standard versions. They are available in two types of housing and in a number of versions.
Designed specifically for use in atmospheres in which explosive mixtures are or may be present, certain design considerations must be observed.
The standard red IS manual call point is EN54-11:2001 compliant and has a resettable element. The range uses an IP67 weatherproof polycarbonate housing and is available in colours other than red. A transparent hinged cover part no: 26729-152 is available for protection against accidental operation.
