Page 5: General Information
General information The control unit module Alpa MOD LED1 is a single-channel control device designed for operation at facilities with a risk of hazardous gases presence, for instance toxic gases (CO, NOx), flammable gases (CH4, LPG) or any other gases that can be monitored by means of appropriate detectors. The complete system is... -

(OPERATION, SUPPLY, R4). Warning This condition occurs when a small gas leak is detected that requires user notification in order to take appropriate control measures. Control Unit Module Alpa MOD LED1 distinguishes between two warning thresholds: 4.2.1... -
Page 7: Failure
www.atestgaz.pl the system turns on the OC ALARM, to control the external signaller, the 3 relay (ALARM) and the green 3 control (1 and 2 sustained) are activated. Action to be taken when ALARM is signalled: remove unauthorized persons from the afected area, as far as possible, allow ventilation of the premises which are at risk –... -
Page 8: Relay Outputs R1 - 4
The detector is connected to the control unit using a three-wire cable to the appropriate terminals + S -. Signaller to the terminal OC Output (+12V, OC1, OC2). Control Unit Module Alpa MOD LED1 has 4 relays with potential-free contacts that can be used to control automation systems, signalling or ventilation systems (eg a two-speed fan). When performing these installations, remember that for safety reasons, the device is without a mains switch. -

www.atestgaz.pl 8.3.2 Test for the system with an open control loop To carry out the test for a system with an open control loop please remove the lid of the last detector of the loop and depress the TEST button inside the enclosure. Periodical operations The device should be subjected to periodic inspection of its technical condition. -
Page 12: Technical Specification
Table 3: Technical specification The given value refers to the power consumption only for the Alpa MOD LED1 Control Module. When determining the total consumption by the gas detection system, the power absorbed by all devices in the system should be taken into account, eg detectors, signalling devices, battery charging, etc. -
