Interior equipment: Burglar alarm devices

The burglar alarm installations that PRIMAT d.d. integrates into its products are tested and certified by VdS Schadenverhütung, Cologne, Germany, both as individual components and as a complete installation. 

All Primat safes (security level 3-5) are pre-prepared for the installation of alarm devices.

The alarm devices are connected to a central alarm system. The amount of the burglary insurance payout (in case of burglary) with alarm use is doubled.

1. Acoustic noise sensor - characteristic noise detection

  • It etects the characteristic noises of intrusion tools such as hand and power hammers, drilling machines, abrasive and thermal cutters, diamond tools including crown drill, hydraulic fracturing, explosives, etc. 
  • In the event of a break-in at the door and/or safe housing, it detects a characteristic noise and sounds an alarm 
  • It also detects, but does not react to, normal environmental influences on safes.
  • Its sensitivity level, including time delays, is adjustable 
  • One acoustic (noise) sensor can monitor up to 50 m² of surfaces, but they must be in one part
  • Safes require one acoustic sensor per door

2. Tear sensor - detection of anchorage tears

  • Aarly detection of intrusion attempts to break the anchors of security cabinets, safes and ATM cash registers
  • The tear sensor is located under the head or nut of one of the anchor bolts; if the safe is attempted to be torn from the lining, the sensor breaks and triggers an alarm
  • Despite the alarm being triggered, the anchor bolt still prevents the safe from being removed

3. Magnetic door switch - door position detection

  • It monitors the position of doors of security lockers, safes, ATM cash registers and vault rooms
  • It detects two positions "open" and "closed" 
  • The magnetic switch consists of a permanent magnet, usually mounted on the door, and a switch on the safe's housing 
  • In the "door closed" position, the permanent magnet triggers a closed circuit in the alarm installation. If the door is moved to the "open" position while the burglar alarm control panel is activated, the circuit is broken and the alarm is triggered. 
  • ATM cash registers are fitted with two switches, otherwise one. The second switch is not connected to the control panel, but registers the opening of the door when the control panel is switched off.

4. Lock latch switch - lock position detection

  • It controls the position of the latchbolt, which is used to lock the safe indirectly via the latching mechanism
  • It detects two latch positions: "locked" and "unlocked" 
  • The switch operates by creating a closed circuit in the alarm installation when in the "locked" position 
  • If and when the latch is moved to the 'unlocked' position by unlocking the lock with the burglar alarm device activated, the circuit is broken and the alarm is triggered

5. Lid/latch door switch - detection of unauthorised opening of the lid or latch door  

  • It detects an unauthorised opening of the lid or door of that compartment
  • The switch operates by establishing a closed circuit when the latch cover is closed and/or screwed on
  • If the cover/door is removed or opened, the circuit is interrupted, the control panel rejects it and/or triggers an alarm

6. Divider with cover switch

  • It connects different alarm components to each other and to the control panel
  • The security purpose of the divider control is to detect unauthorised opening of the divider cover
  • the switch of the divider cover operates in such a way that when the divider cover is closed and screwed down, a closed circuit is established in the alarm wiring
  • When the divider cover is unscrewed and removed, the control panel registers this and/or triggers an alarm
  • For security cabinets, safes and ATM cash registers, there are two dividers, one in the door and the other in the casing

7. Locking element - forced lock control

  • Provides additional mechanical protection of the safe door
  • It acts by establishing a rigid connection between the element and the latch of the lock when it is in the "locked" position
  • When the control panel is switched on, the locking element is activated and blocks the movement of the latchbolt via a lever
  • The lock cannot be unlocked by the holder of the opening code (key) while the locking element is engaged
