Brand Information Discovery® is a range of high-specification, analogue addressable fire detectors and alarm devices. Discovery detectors offer effective false alarm management by a combination of EN 54 approved operating modes and sophisticated algorithms.
Drift compensation further reduces the likelihood of false alarms caused by a build-up of dust in the sensing chamber.
In addition to the familiar smoke and heat detectors, the Discovery range features two multisensor detectors. One is an optical/heat multisensor which can be used to protect against many types of fire risk. The other is a carbon monoxide/heat multisensor which protects against both smouldering fires and those generating heat.
Operation The Apollo Discovery Manual Call Point has been designed to operate on a loop of intelligent fire detection devices. An alarm is initiated by pressing the resettable element. The manual call point signals to the control and indicating equipment using an interrupt feature within the Apollo digital communication protocol.
An alarm status is indicated by a yellow and black bar in the lower section of the resettable element and a red LED. The manual call point can be easily reset from the front using the supplied reset key. It is available in two versions, with and without isolator. The manual call point is intended for indoor applications.
Device Addressing The address of each call point is set at the commissioning stage by means of an a seven segment DIL switch. The address switch is accessable without removing the call point from the mounting surface.

Maintenance & Service Detectors should be maintained according to BS 5839-1 or other locally applicable code. Test equipment can be ordered from Apollo for testing smoke and heat detectors.
Detectors should not be cleaned in the field except for careful removal of exterior dirt with a damp cloth. For cleaning and recalibration detectors should be returned to Apollo Fire Detectors or to the local distributor.
EMC Directive 2014/30/EU The product complies with the essential requirements of the EMC Directive 2014/30/EU, provided that it is used as described.
Construction products regulation 305/2011 The product complies with the essential requirements of the Construction Products Regulation 305/2011.
Additional Information A red alarm LED is provided on the manual call point. This LED is controlled independently of the manual call point, by the fire control panel.Once activated, the manual call point can be reset by inserting the reset key into front facing LED, turning clockwise until a positive click and reset occurs. An additional pack of 10 reset keys can be purchased, Part Number 44251-176.
The isolated version of the manual call point incorporates a short circuit isolator which will ensure its operation in the event of a short circuit fault on the loop. Isolator operation is indicated by a yellow LED. For further details of the isolator refer to datasheet PP2090, available on request.
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.
