Door lock module
This module is used for lock-gate organization (up to 3 doors). It could be successfully used for remote door control too.
Module has three groups of contacts:
Work with one door: enable/disable inputs and outputs do not used; visitor press door call button, duty receives that signal and opens the door. Work with two/three doors (lock-gate): enable/disable inputs and outputs of modules are connected to each other, thereby, any door could not be opened, if other one is opened already. Status LEDs show, which door is opened right now. Relay contacts of door lockers are designed for current consumption of 220V 6A. Relay open time's limit prevents lock' heat damage.
Used for connection of power supply, accumulator and output load.
Device provides:- uninterruptable 12 VDC 3 A power supply;
Phone automatic dialer
Phone Dialer is used to call and send voice alarm message to programmed subscribers in case of incoming alerts.
Features:- Alarm message duration: 16 sec
Relay modules is used for communication between guard devices (controllers) and process execution modules.
On-door speakerphone controller
Used to extend abilities of single on-door speakerphone. Controller is connected with keypad and local PBX. When the key is pressed, controller calls to the phone number, corresponding to the selected apartments, and waits command to open door lock.
12VDC to 24VDC converter
Pulse DC/DC converter with high efficiency, output current - 1A. Used for 24V electrical locks control from 12V
Precision 50Hz clock
This device generates pulses of stable frequency 50 Hz in the presence of unstable frequency on input. Usage: imported equipment adaptation to Estonian (other post Soviet) mains. Time error: ~15 sec per month
Power supplies with transformer inputs and battery charge circuits:- 13,8 VDC / 0,5 A
Device is provided with two launch input with operating voltage 0-24V, three relay outputs (5A, 5A, 1A) and three led indicators.
Delay can selected in binary code at ranges: 1..16 s, 1..16 min or 5..80 min.
Device can provided with 12-key keyboard.
DTMF communicator is used for sending alarm messages to guarding center through telephone line.
Principle of operation:Communicator is connected to power supply, safety-alarm device and telephone line release. Device has four alarm inputs: ALM1, ALM2, ALM3, ALM4. Normal statement of those inputs is high potential (5..12V) or open condition. Case alarm (low potential on inputs ALM1..ALM4 or short condition) the device disconnects telephone and makes call to predefined phone number and sends alarm message; if call is unsuccessful, device repeats an attempt. It was possible to define two phone numbers of security centers, alarm on ALM1 and ALM2 will cause sending message to the one phone number, on ALM3 or ALM4 to another.For programming the device is used simple utility ContactIDCom.
Technical information:Alarm inputs 4
Microphone amplifier is used for microphone signal transmission within range up 100m. Generally used together with monitoring cameras.
Battery discharge guard
Battery discharge guard (BDP) has five terminal blocks: three of them are relay contacts, two - power supply. Relay contacts turns on if the battery voltage is over 11.5V, and turns off if less than 9.3V; thereby, BDP prevents battery full discharge and provides undisturbed operation of guarding devices.
