Apollo XPander CS Heat Detector XPA-HT-11171-APO

Apollo XPander CS Heat Detector XPA-HT-11171-APO

Apollo XPander CS Heat Detector XPA-HT-11171-APOThere are two heat detectors in the XPander range designed to suit a wide variety of operating conditions. A Static Heat Detector CS which responds only when a fixed temperature has been reached and a Rate-of-Rise Detector A1R which has a fixed upper limit but in addition measures the rate of increase in temperature.Key FeaturesWireless Can be used in applications where smoke detectors are unsuitable Ideal for environments that are dirty or smoky under normal conditions CS detectors are ideal for use in environments with rapid temperature fluctuations such as boiler rooms Bi-directional monitored radio platform Five-year battery life using standard AA alkaline batteries

System Sensor M220EA Dual Input or Monitor Module

System Sensor M220EA Dual Input or Monitor Module

System Sensor M220EA Dual Input or Monitor ModuleThe wired range of Input Output modules has been redesigned to address its microcontroller obsolescence and grant full backward-compatibility.The M220EA monitors one or two sets of normally open contacts and has two tri-colour LED indicators One for each channel. The fire panel can be configured to switch the relevant channel indicator on red in the event of an alarm on an input channel. The indicators can be set by panel command to pulse green each time the module channel is polled. The relevant indicator blinks yellow if the module detects an open-circuit on the input circuit.This module features automatic fault supervision and a built-in isolator on the analogue addressable circuit. The isolator may be bypassed.Two mounting holes and a pair of DIN rail clips allow the module to be installed in any type of enclosure including a purpose-built surface-mount box M200E-SMB. The indicator LEDs and address switches are accessible and visible in both DIN-rail and surface mount installations.Key FeaturesIndividually addressable by the fire panelInput circuits supervised for open-circuit faultsTri-colour indicator LEDs visible from front and one sideAutomatic detection of short-circuits on AA circuitAA circuit short-circuit isolatorOptional isolator bypassScrewdriver operated rotary address switches accessible from front and one sideClips for top hat 35 mm DIN railTwo mounting holesUp to 99 module addresses per AA circuit F220 F100AUses two addresses on the analogue addressable circuitPlease note This product requires the M200E-SMB for surface mounting or M200E-DIN for mounting to DIN rails.

Apollo XPander A1R Heat Detector XPA-HT-11170-APO

Apollo XPander A1R Heat Detector XPA-HT-11170-APO

Apollo XPander A1R Heat Detector XPA-HT-11170-APOThere are two heat detectors in the XPander range designed to suit a wide variety of operating conditions. A Static Heat Detector CS which responds only when a fixed temperature has been reached and a Rate-of-Rise Detector A1R which has a fixed upper limit but in addition measures the rate of increase in temperature.OperationHeat detectors have an open-web casing which allows air to flow freely across a thermistor which measures the air temperature every 2 seconds. A microprocessor stores the temperatures and compares them with pre-set values to determine whether a fixed upper limitthe alarm levelhas been reached. In the case of rate-of-rise detectors the microprocessor uses algorithms to determine how fast the temperature is increasing. Static heat detectors respond only when a fixed temperature has been reached. Rate-of-rise detectors have a fixed upper limit but they also measure the rate of increase in temperature. A fire might thus be detected at an earlier stage than with a static detector so that a rate-of-rise detector is to be preferred to a static heat detector unless sharp increases in temperature are part of the normal environment in the area protected by the heat detector.Key FeaturesWireless Can be used in applications where smoke detectors are unsuitableIdeal for environments that are dirty or smoky under normal conditionsCS detectors are ideal for use in environments with rapid temperature fluctuations such as boiler rooms Bi-directional monitored radio platformFive-year battery life using standard AA alkaline batteries
